  1. Twins alternate site pitching coach Mike McCarthy is a broad thinker and big doer, but right now, his professional world is very small. Nonetheless, he and the Twins are working hard to continue developing and preparing hurlers at CHS Field.McCarthy, 33, is no more naturally suited to the seclusion and sterilized atmosphere of the alternate site than are his highly competitive charges. However, he and the team have found ways to make the most of the situation. “It’s a really difficult challenge,” McCarthy said of keeping pitchers working at a high level in simulated games that often feature fewer than six fielders and a small rotation of two or three batters per half-inning. “So we add runners on base, we’ll start them with a dirty inning, we’ll try to give them as game-like an environment as possible.” By calling out various situations and asking pitchers to work within the simulated constraints, he and other Twins staffers can kindle the competitive fire a bit even under tangibly bizarre circumstances. Even so, the day-to-day work in St. Paul isn’t an adequate replacement for minor-league competition, nor a good way to keep pitchers ready for quick recall to the big leagues. To turn the strange setting to their advantage, therefore, the team treats it almost like a constant workshop. “This can be an opportunity for development--for guys to work on things like that,” McCarthy said, noting the Rapsodo camera that sits on the ground between the mound and home plate throughout sim games. “We can give them a quicker feedback loop than, say, in a game in the major leagues, where you can’t pull your TrackMan data and look at how the pitches are moving, or locations, all of those things. We can do that in real time here, and look at those things in between innings, so we’re leveraging that.” In the majors, relievers have to be ready to pitch every day. While they’re with the alternate-site crew, the pitchers are kept on regular schedules, for both health and logistical reasons. “We’ve said, ‘hey, let’s set them on a schedule, so they know when they’re throwing.’ That also keeps us more COVID-compliant, with limited facility access and keeping guys spread out, and because we are short on players and staff,” McCarthy explained. “What we’re doing is trying to stagger that so that they have opportunities to throw on set days.” To simulate the varying urgency of game situations, though, the coaches sometimes don’t tell players whether they’ll pitch the top or bottom half of an inning until the last possible moment, forcing them to get ready quickly or stay loose for a few extra throws in the bullpen, the way they’ll have to if and when they’re needed in a competitive setting. Primarily, though, the camp can be used to extend the processes the team implemented during spring training, helping pitchers become their best selves. McCarthy talked about the way he and his colleagues have continued their work with Derek Law over the first month of the season, culminating (for now) in his inclusion on the taxi squad for this week’s trip to Cleveland. “Derek obviously had a really good spring training. We really helped him understand how to utilize his mix better,” McCarthy said. “Something that has been a strength for him is his ability to throw his breaking ball for strikes, and to locate extremely well. So we’ve just tried to maximize that, and to add a little bit of carry to the fastball. He’s been phenomenal. He’s continued to do what he did in spring training, continued to work on understanding how to use his profile best, and how to pair his pitches together.” Those have been easy changes to maintain. Whether they’ve continued to tighten and are sharp enough to withstand the vicious test of a high-leverage situation in a big-league game is yet to be seen. In the meantime, McCarthy, Toby Gardenhire, and other Twins staff are doing their best to navigate the major vestigial challenges of pandemic baseball.

  3. The Twins recalled Cody Stashak from the alternate site in St. Paul on Sunday. For Stashak, the time at CHS Field was spent honing his slider and changeup, but the key to his success might be throwing consistent, quality strikes with his fastball.Stashak’s greatest strength, as a pitcher, is the carry on his four-seam heater. With his extremely high arm slot and above-average spin rate, he can miss bats and induce weak contact at the top of the strike zone. However, his raw velocity is below-average, and his short stature and delivery combine for little extension at release. Thus, when Stashak isn’t elevating that fastball enough, the pitch flattens out and batters can tee off. In Stashak’s career, over 13 percent of the batted balls he has allowed have been classified as Barrels by Statcast, meaning that they result in hits at least half the time (and often in extra-base hits). That rate makes it hard to sustain much success at all, and especially hard to earn a high-leverage relief role, because damaging batted balls are even more problematic when the game hangs in the balance. While he was at St. Paul with the rest of the Twins’ alternate-site roster, Stashak focused primarily on his secondary stuff, according to alternate-site pitching coach Mike McCarthy. That’s one way he can keep hitters off of his fastball: by using changes of speed and eye level to keep them honest. “Throwing the changeup is still a priority for Cody,” McCarthy said. “We feel like it’s obviously an elite fastball in terms of its vertical break, but giving him an opportunity to add some depth to the changeup and get that third pitch as an option can make that [fastball] a little more of a weapon.” Stashak’s slider has also been an exceptional weapon since his big-league debut, with tight, vertical movement and a high “miss rate,” as McCarthy called it. However, the pitch has enough lateral movement to give lefties a slightly earlier hint that it’s coming, so he’s been much more effective against right-handed batters while leaning mostly on the four-seamer and breaking ball. His 35-percent career strikeout rate against righties makes him nearly elite, whereas he’s whiffed only 22 percent of lefties, an essentially average clip. Because of his vulnerability to homers, Stashak can’t be a merely average strikeout arm. He’ll be good only if his strikeout rate is great. “If we give him a third weapon and help him develop [the changeup], it’s going to be a huge advantage for him to get left-handed batters out,” McCarthy said. Last year, Stashak did increase the depth on his changeup slightly, though it still wasn’t a pitch on which he could rely consistently. His arm slot and the position he takes on the first-base side of the rubber do give him good angles for throwing the change with more vertical movement, though, and McCarthy and the Twins are optimistic that he can continue to hone that pitch while using the slider as the principal complement to his heat. Alas, one other bugaboo reared its head during Stashak’s time at the alternate site: he still makes too many mistakes with the fastball itself. No matter how well he and the team shape and tweak his other offerings, he’ll be in big trouble unless he can hammer the top of the zone with that pitch. At least twice during his stint in St. Paul, Stashak gave up home runs to teammates hitting against him. He left his appearance last Sunday at CHS Field cursing into his mitt and complaining to his catcher that he was unable to throw his fastball for strikes. In his case, that usually means missing well above the zone, or pulling the ball to the glove side and missing away from right-handed batters. Whenever that’s happening, he’s forced to use the big part of the zone with his other pitches, and the odds of hard contact rise. All three of the hard-hit balls that led to the Pirates’ multi-run rally against Stashak Sunday at Target Field came on the slider, and he didn’t throw his changeup at all during the contest. In fact, he only threw four fastballs out of his 19 pitches, a reflection of his ongoing struggle to find control and confidence on that pitch. Given his size and his style, Stashak can’t afford to trade much of his sheer power for stability or command. That doesn’t mean he can’t clean up his mechanics, but the impact of the changes he could make is likely to be small. Unless he can simply find the release point that allows him to attack the spots where he can win with that pitch, he’s going to remain an unreliable middle reliever, and he could soon find himself back in St. Paul. In the meantime, the Twins can only arm him with information and counsel patience, for a pitcher fighting both a mental and a physical battle with himself.

  5. The Twins are in an indefinite holding pattern as they deal with an outbreak of COVID-19, but at their alternate site, action continued this weekend. Here are five takeaways from their Sunday workouts and simulated game.Blankenhorn Called Up to Taxi Squad; Kirilloff Still in St. Paul The implications of the decision are inscrutable, but the Twins added Travis Blankenhorn to their taxi squad after the postponement of their games against the Angels this weekend. Blankenhorn had not been on the initially reported taxi squad for the road trip to Anaheim and Oakland, so his absence from St. Paul is of some note, especially given the expected roster upheaval whenever the team does take the field again. Meanwhile, however, Alex Kirilloff remains in St. Paul. He took batting practice and participated in the team’s brief simulated game, getting in good swings off the likes of Derek Law and Juan Minaya. Apparently, the Twins still don’t feel that Kirilloff has built the developmental momentum they want him to have before permanently adding him to the parent club. Forgotten Man Ben Rortvedt a Solid Fallback Plan at Catcher After Ryan Jeffers’s ascendant 2020, it became easy to lose sight of Rortvedt, as the Twins appear well-fixed at catcher. Should either Jeffers or Mitch Garver suffer an injury, though, Rortvedt would be well-positioned to get the call. The lefty-swinging 23-year-old is already on the 40-man roster, which could give him a leg up over Caleb Hamilton or Tomás Telis, and on Sunday, he took Cody Stashak deep at CHS Field. He caught half the simulated game in addition to getting his licks in, and looks the part of a solid backup backstop in the majors even now. Juan Minaya’s Changeup Plays One thing CHS Field does not currently offer fans or players is a live scoreboard with velocity readings. However, it does afford fans close-up views, so it’s possible to get a quick, amateur assessment of certain pitchers’ stuff based on the way the ball comes out of their hand and on the reactions they get from hitters. Minaya was impressive in an inning-plus of work Sunday, including a changeup that flummoxed Kirilloff for a strikeout. Though he hasn’t pitched in the big leagues since 2019, Minaya was briefly an effective big-leaguer, with a fastball that sat at 94 or 95 miles per hour. His changeup was his best pitch then, too, and he used it to run reverse platoon splits. (In other words, he was better against left-handed batters than against fellow righties.) I overheard two Twins hitters talking about his stuff prior to his appearance, and they were under the impression that his fastball was sitting at 97. If true, that’s a significant development for the non-roster bullpen hopeful. Whatever speed the fastball had, though, the changeup played off it nicely. A Good Environment for Development, Perhaps; For Evaluation and Preparation, Not So Much Like the other 29 teams, the Twins are ardently making the most of the situation while they await real minor-league games. Coaches talk up the benefits of the unique setting from a development and feedback perspective. It’s not hard to buy into that, when watching a pitch sail over a Rapsodo camera a dozen feet in front of home plate, or when hearing about the way the team can offer players immediate and thorough feedback after each session. However, from every other perspective, it’s a profoundly diminished thing. Fans should attend workouts only if they’re exceptionally eager to see baseball movements and delight in the details of practice. The game-level fan experience can only be called soporific. The atmosphere is sterile. Whole swaths of the field went unmanned Sunday, as the team worked even more shorthanded than usual. No serious conclusions about any player’s ability to make key adjustments or handle game situations can be drawn from what is happening in St. Paul. Nor can any objective observer argue that those workouts are preparing players adequately for big-league contests. Everyone involved is doing their best, and it’s not a worthless exercise, but it’s even further from the optimal minor-league setting than you would imagine. Nick Gordon Doesn’t Look Like a Useful Utility Man Speaking of someone doing their best (but their best not necessarily being sufficient), Nick Gordon took some early infield practice at shortstop. It wasn’t encouraging. Persistently struggling to get off strong throws from the hole, Gordon also began dropping or mishandling balls to his backhand side at a high rate as he tried to speed up his pick and transfer. Making mistakes is why you take the extra reps, and they can make you better. At this stage of his development, though, Gordon shouldn’t be having as many problems as he was having on that play, if he’s ever to provide value with his glove on the left side of the infield. This has been the biggest problem for Gordon for a couple of years now. Ever since he settled into what looked like a low-ceiling offensive profile, the question has been whether he would be able to play anywhere but second base on a big-league infield. Unfortunately, the answer seems to be no, and the process by which he would change that at this stage is hard to envision. If the Twins hope for help from the alternate site in case of further depletion on the infield, it will probably have to come from Blankenhorn’s bat or the glove of Tzu-Wei Lin.

  7. Luis Arraez put his offensive skills on full display on Opening Day, and his defensive home for the first part of 2021 became a bit clearer. Meanwhile, a contract extension 2,000 miles away further clarified what it would take for the Twins to lock up Arraez.Josh Donaldson’s hamstring tightness figures to open up even more playing time for Arraez at that position than the Twins were anticipating, at least in the short term. Manager Rocco Baldelli said even before Donaldson got hurt that he would be looking to slot Arraez into the lineup as often as possible, as the leadoff hitter. In the first game of the season, Arraez rewarded that profession of faith by collecting two hits (and having a third stolen on a dazzling defensive play) and drawing a walk. If you were dubious that the Twins would find something close to 600 plate appearances for Arraez this year (should he stay healthy enough to claim them), recent developments should have put those doubts to rest. From optioning Alex Kirilloff to starting Arraez in left field on Thursday to Baldelli’s commitment to using him as the leadoff hitter, and especially in the wake of Donaldson’s misfortune, all signs point to a vital role for Arraez in the team’s plans for the entire season. It might also be time to think beyond this season, though. In the hours just before the Angels opened their season with a 4-3 win over the White Sox, the team announced that it had signed a five-year, $26-million extension with second baseman David Fletcher. The deal could stretch to seven years and almost $40 million, as the Angels hold two club options. Fletcher, 27 next month, is three full years older than Arraez, but he’s also a year closer to free agency. Though he bats right-handed, he’s extremely similar to Arraez at the plate: below-average power, but top-tier skills in other offensive areas. No one — not even Arraez — makes contact on a higher percentage of swings than does Fletcher. He’s versatile, too, but a better defender at each infield spot than Arraez is. The Angels didn’t have extraordinary leverage over Fletcher in negotiating this deal. Though he’s a slightly late bloomer, Fletcher could have hit free agency at about the same age at which Tommy La Stella just did so. La Stella, another player very similar to Fletcher and Arraez, signed a three-year deal worth $19 million. Six and a half years ago, Fletcher signed for an above-slot $406,000 after the Angels took him in the sixth round. There’s significant value in the certainty he just gained by signing a long-term deal, but he probably would have made at least this much if he had merely gone year-to-year until reaching free agency. Moreover, he’s already made somewhere close to $1.5 million as a professional ballplayer. Though there are special circumstances involved in both Fletcher’s deal and the one Ozzie Albies signed with Atlanta two years ago, the contracts can’t be dismissed as data points in any conversation about an Arraez extension. I wrote about what an Arraez deal could look like last month, and intentionally shot a hair above the market rate, because I felt that the relevant precedents for such a deal were unfairly underselling the skill sets of the players in question, including Arraez. However, the Fletcher deal further sets that market, and at this point, I’m forced to admit that any five- or six-year deal (even with club options attached) between the Twins and Arraez would only need to guarantee the gifted hitter about $25 million. Given that reality, the Twins would be nuts not to be talking to Arraez and his representatives about getting a deal done. There is nothing to be gained by waiting. If there’s a deal to be done that will allow the Twins to capture real upside during what would otherwise be Arraez’s most expensive arbitration-eligible seasons and his early free agency, and the total cost is only the rough equivalent of Donaldson’s annual salary, then they need to pounce on the opportunity. In the meantime, Arraez will certainly be pouncing on his. However stretched he might be as an everyday third baseman, he’s secure at that position for as long as Donaldson is out, because the Twins lack a realistic alternative. Despite his limitations, Arraez is indispensable to this Twins team, and he might well prove to be a key cog for an AL Central dynasty. Given how cheaply they could ensure that, the Twins should be very excited about the prospect.

The Angels didn’t have extraordinary leverage over Fletcher in negotiating this deal. Though he’s a slightly late bloomer, Fletcher could have hit free agency at about the same age at which Tommy La Stella just did so. La Stella, another player very similar to Fletcher and Arraez, signed a three-year deal worth $19 million. Six and a half years ago, Fletcher signed for an above-slot $406,000 after the Angels took him in the sixth round. There’s significant value in the certainty he just gained by signing a long-term deal, but he probably would have made at least this much if he had merely gone year-to-year until reaching free agency. Moreover, he’s already made somewhere close to $1.5 million as a professional ballplayer. Though there are special circumstances involved in both Fletcher’s deal and the one Ozzie Albies signed with Atlanta two years ago, the contracts can’t be dismissed as data points in any conversation about an Arraez extension. I wrote about what an Arraez deal could look like last month, and intentionally shot a hair above the market rate, because I felt that the relevant precedents for such a deal were unfairly underselling the skill sets of the players in question, including Arraez. However, the Fletcher deal further sets that market, and at this point, I’m forced to admit that any five- or six-year deal (even with club options attached) between the Twins and Arraez would only need to guarantee the gifted hitter about $25 million. Given that reality, the Twins would be nuts not to be talking to Arraez and his representatives about getting a deal done. There is nothing to be gained by waiting. If there’s a deal to be done that will allow the Twins to capture real upside during what would otherwise be Arraez’s most expensive arbitration-eligible seasons and his early free agency, and the total cost is only the rough equivalent of Donaldson’s annual salary, then they need to pounce on the opportunity. In the meantime, Arraez will certainly be pouncing on his. However stretched he might be as an everyday third baseman, he’s secure at that position for as long as Donaldson is out, because the Twins lack a realistic alternative. Despite his limitations, Arraez is indispensable to this Twins team, and he might well prove to be a key cog for an AL Central dynasty. Given how cheaply they could ensure that, the Twins should be very excited about the prospect.

  9. The Twins’ first series of 2021 finds them in a National League park, facing the NL Central favorites. Here are the probable starters, a few scouting reports, and the keys to winning the series.Probable Starting Pitchers Thursday, 1:10 PM CT: RHP Kenta Maeda vs. RHP Brandon Woodruff After giving spring test drives to some “new” pitches (he already throws them all, but was exploring the potential of increasing their usage), Maeda takes the ball for his first Opening Day start in the United States. His three-pitch mix of four-seam fastballs, sliders, and changeups was more than equal to the task of dominating the Brewers last summer, when he famously flirted with a no-hitter and struck out eight Milwaukee batters in a row. This year, the Crew has added two solid left-handed batters, in Jackie Bradley, Jr. and Kolten Wong, but Maeda’s sterling 2020 was built on becoming more unpredictable and more dominant even against lefties. If he feels good about the progress he made on his curveball throughout the Grapefruit League, he should break it out right away. Woodruff has morphed from a guy with great stuff but iffy command into a borderline ace by learning to use both his four-seam fastball and his sinker to great effect. Already armed with a nasty changeup, Woodruff becomes truly overpowering when he can command his heat. His four-seamer has exceptional rising action at the top of the zone, and misses bats as well as almost any fastball in the league. The sinker, meanwhile, manages contact and forces hitters to cover the whole plate. Saturday, 6:10 PM CT: RHP Jose Berrios vs. RHP Corbin Burnes I wrote about what I wanted to see from Berrios prior to his first start of spring training, and he checked all of those boxes. He’s showing the ability to shape his breaking ball according to the opposing hitter and the situation; the confidence to throw his changeup more often against fellow righties; and the intent to hit the outside corner against righties with his four-seamer. Now, his challenge is to carry those important developments over into games that count. When Burnes tried to be a hypermodern hurler, using his four-seamer and slider to maximize strikeouts, he was unable to stay out of the heart of the plate. Hitters noticed, and delivered ringing rebukes in the form of a barrage of home runs throughout 2019. In 2020, though, Burnes came back as a sinker-cutter guy, with the ability to aim for the middle of the plate and let the pitches veer off in opposite directions. Twins hitters will need to go to the plate knowing what they’re looking for and planning to swing early; Burnes is ruthlessly efficient about putting opponents away in two-strike counts. Sunday, 1:10 PM CT: RHP Michael Pineda vs. RHP Adrian Houser The Brewers will probably trot out their best lefty-loaded lineup against Pineda, hoping that his slider has less than its usual depth and that they can tee off on his fastball. Pineda’s changeup was quite poor in 2020, which is understandable. He’d been held out of competition for over a year, and changeups tend to rely on a level of feel and confidence that can be hard to maintain under such circumstances. Still, if Pineda wants to have a strong 2021, he needs to remaster that pitch, and his first start will be a good test. Whereas Pineda needs his changeup purely as a third pitch, though, Houser needs it just to have anything to keep left-handed hitters at bay. They bash his sinker-slider combination mercilessly, which has hampered his attempts to stick as a big-league starter—despite good velocity and movement. He tried out a new version of the change this spring, but look for the Twins to empty the bench of lefty bats (Jake Cave and Luis Arraez should almost certainly be in the lineup) to force him to prove the new offering works. Scouting the Brewers: Milwaukee breaks camp with a deeper bench than almost anyone else in the league, in terms of the sheer number of bodies Craig Counsell will have available. While Opening Day politics might dictate that Keston Hiura or Jackie Bradley, Jr. starts Thursday, Counsell will freely mix and match, platoon players, and make aggressive substitutions based on late-game situations. Dan Vogelbach, the beefy left-handed first baseman-slash-DH, lurks as a likely pinch-hitter in pretty much any key spot. If the Twins have any concerns about Hansel Robles, Jorge Alcalá, or Cody Stashak facing a tough lefty, Rocco Baldelli will need to be aware of his lineup card when he turns to them. Because of the versatility of Milwaukee’s other bench pieces, Vogelbach could bat for Hiura, or for Luis Urías, or for Lorenzo Cain. Urías takes over as the everyday shortstop, to open the season. Orlando Arcia remains in the mix, but will wait for opportunities to sub in for defense and spell Urías, whom the Brewers got in a trade with San Diego during the 2019-20 offseason. Last year. Urías didn't look like the well-respected hitting prospect he had previously been, but his bat looked much quicker this spring. Travis Shaw is back at third base, though the Brewers will use a handful of players at that position over the course of the season. His presence allows the team to load its lineup card with lefties when a righty starts, but outfielder Avisaíl García could bat for him if the Twins go to Taylor Rogers or Caleb Thielbar in a key moment. Only three teams shifted more often than did the Brewers in 2020. Look for Max Kepler to face a shift every time he steps to the plate. The same will probably be true for Miguel Sanó and for Byron Buxton. More broadly, after adding Bradley and Wong and with Cain returning from opting out of 2020, the Brewers have one of the best team defenses in baseball. The Twins will need to play some long ball in order to score. The Brewers have a deep stable of hard throwers, including all three of their starters for this series, so if Sanó’s bat remains as slow as it looked during much of the spring, he could be in for a tough series. (Then again, the sinkers Woodruff, Burnes, and Houser each throw tend to run right into Sanó’s preferred bat path.) Prediction: The first two games of this series are virtual toss-ups. The Twins are a better, deeper team, but the Brewers make excellent use of their own depth, and they have the advantage of having all of their interchangeable pieces fresh and ready for this matchup. On Sunday, though, the Twins have a clear edge, because Houser should really struggle against this Minnesota offense. If things go according to plan, the Twins should take two out of three to open 2021. Click here to view the article

  11. Andrelton Simmons and Byron Buxton missing significant time is more a question of ‘when’ than one of ‘if’. That truth informed several moves the Twins made this winter, and will continue to shape their choices over the coming days and weeks.As I wrote yesterday, Simmons and Buxton rate as the two hitters facing the greatest injury risk, according to new models built by Sports Info Solutions for predicting injuries. It wasn’t the focus of yesterday’s article, but the same model also marks Josh Donaldson (unsurprisingly) as a source of above-average injury risk, thanks to his age, the chronic nature of his recent calf injuries, and his hard-nosed defensive style at third base. All three of those guys are talented enough to be worth the roll of the dice, but the Twins couldn’t rely on the trio without giving themselves more than the usual allotment of backup options. Starting second baseman Jorge Polanco is the chief backup shortstop, of course. Still, once Royce Lewis turned up with a knee injury (as it turned out, a very serious one) to open camp, the team gave a spring audition to Andrew Romine. After exercising the release clause in his deal, Romine is now a free agent again, but the Twins are comfortable with that partially thanks to Polanco’s apparent health and ease of movement this spring. Riddle does not have an immediate release clause in his minor-league deal, though, so the team can keep him around as emergency depth at that position. Keeping Luis Arraez out of left field, at least at first, was also a response to the risks associated with the infielders starting ahead of him. It was an expression of the organization’s belief (which probably still holds, for the most part) that playing time would open up for Arraez on the infield sooner than in the outfield. Speaking of the outfield, though, the team needs to have a more qualified medium-term answer for a Buxton injury than sliding Jake Cave or Max Kepler into center field. To that end, they have Keon Broxton in camp. Broxton’s non-roster deal includes a release clause, but it doesn’t kick in until midseason. That means that the Twins can carry him at the alternate site, and then as a member of the Triple-A St. Paul Saints, until the summer, unless they need him sooner. Once he’s called up, however, he can’t be optioned. For that reason, don’t expect Broxton to make the Opening Day roster; he’s being kept as dry powder for the inevitable exigency of Buxton going down. Travis Blankenhorn provides a very different shape of offensive value than Arraez, but he can be a solid left-handed batter and play a couple of infield spots if needed. Gilberto Celestino could use a healthy chunk of playing time to continue his development in the minor leagues, but he’s already on the 40-man roster. In Polanco, Arraez, Blankenhorn, Celestino, Cave, Riddle, and Broxton, the Twins have cobbled together sufficient depth to weather the injury trouble they’re likely to encounter as a result of having Simmons, Buxton, and Donaldson crowded onto one roster. That doesn’t make them invincible. Arraez or Polanco could get hurt at an interval that overlaps with the absence of Simmons or Donaldson, forcing Riddle into action early and forcing the team to waive him once everyone gets healthy. Buxton could get hurt almost right away, prompting a Broxton call-up and a subsequent DFA, leaving Celestino as the sole firewall for the rest of the year. Still, despite the significant additive, individual risks the club faces, the front office has put together a sufficiently deep and versatile crew to withstand the risks they’ve chosen. It’s tempting to think of health as a matter of pure luck; the new models from SIS belie that notion. If a team methodically assesses their health risks and builds redundancies to soften them, then it really does take a horrific streak of bad luck to turn things sour. If the Twins edge out the already-depleted White Sox in this year’s AL Central race, it might well be because they were more proactive about thwarting the likely impact of injury luck.

  13. According to a new model for injury prediction from Sports Info Solutions, Andrelton Simmons is the position player most likely to miss time due to injury in 2021. Next on the list? Byron Buxton. We talked to a co-creator of the model to find out why.Obviously, it will come as no great shock to Twins fans that Buxton is considered one of the league's biggest injury risks. He's battled concussion issues, shoulder injuries, and wrist trouble. He's suffered from back spasms, had toe trouble, and strained his groin. He's even had migraines, perhaps as a secondary symptom of repeated concussions. Simmons is also known for his fragility, but since he's new in town, Twins fans might be surprised to learn that he is not only more likely to get hurt than Buxton, but more likely than any other big-league regular. Nonetheless, the highly sophisticated system co-created by Sports Info Solutions (SIS) colleagues John Shirley and Matt Manocherian says precisely that. To find out more, I talked to Shirley about how the analysis was performed, and on what it's based. Video scouts employed by SIS watch every big-league game, every season. As far back as 2015, they have logged not only the movements and actions on every play of each game, but also all injury-related events. According to Shirley, this ranges from the obvious (and easily found elsewhere) like players being helped off the field with major leg injuries to the almost unnoticeable (and rarely logged), like a player rolling their ankle on a base but staying in the game, or being hit by a pitch in a certain body part, or grabbing their arm between pitches. All of those injury events are catalogued and cross-referenced with other sources, such as injured list transactions. Where needed, the company's injury coordinator, John Verros, follows up on the report. "For instance," Shirley said, "John might check whether a player rolled an ankle inward or outward, and adjust the prognosis on that basis. It's that level of detail." With that extremely detailed database in place, the co-creators separated hitters from pitchers, to build distinct models for the two player types. For each, they then used machine learning techniques to train the database to predict injuries over various periods—one month, two months, a full season. Shirley noted that the number of layers and data points involved make it difficult to boil down any of the model's findings to a simple explanation. That's reasonable; that web of interdependencies is one reason why it's so hard to predict injuries at all. However, with Simmons, there are certain markers that pushed him toward the top of the list. "I think just that he's such a high-usage player," Shirley said, noting that Simmons "makes a lot of diving plays, covers a lot of ground, is kind of willing to throw his body around a bit." Much of that can also describe Buxton, of course, which has fueled many of his own injury issues over the years. Shirley also noted that, since Simmons has had ankle injuries in consecutive seasons, the model takes not of the risk that such issues can become chronic, or that they can cause injuries at different points in a player's kinetic chain. Both Simmons and Buxton are elite defenders. That, as it turns out, can be a leading indicator of injury problems. Shirley's use of the term "high-usage player" is telling. In other sports, we have become accustomed to the idea that some players bear much heavier workloads than others, even on a per-play basis. Those players are more exposed to injury risk. The same is true in baseball, in ways we might not have fully appreciated until now. Because Simmons and Buxton can get to so many balls, they push their bodies to the limit in efforts to do so. That comes at a higher cost than anyone fully understood, prior to the collection of this much detailed information and the presentation of the findings it fueled. One of the surprising things they found, Shirley said, was that the model often slightly decreased injury risk as players aged. Traditionally, we imagine that players grow more vulnerable to injuries as they age; our bodies break more easily and recover more slowly after age 25. However, players also change their behavior as they age. No longer being able to make certain plays can encourage a guy not to overextend themselves, and they can become more durable even as they become (slightly) less valuable on a per-play basis. For now, Simmons and Buxton are as likely as any other players in baseball to get hurt and miss time. That should sour any solace a Twins fan was finding in the White Sox's misfortune this week. The good news, though, is that the Twins are aware of this, too, and have built their club accordingly. Tomorrow, we'll discuss the implications of these findings when mapping the roster, for Opening Day and beyond.

  15. In his start Monday, José Berríos had an average spin rate of 2,304 revolutions per minute on his four-seam fastball. That was his highest spin rate in a start since Opening Day 2019. It’s a continuation of an encouraging change he made late last year.Because of his arm action and the other pitches in his repertoire, Berríos has never had an especially consistent feel for spinning his four-seamer at the top of the strike zone. He’s shorter than the average starting pitcher, but even adjusting for that fact, he’s tended to release the ball at a relatively low height, indicating a three-quarter arm slot and giving his fastball some tailing action, rather than pure ride. That’s been especially true since his last significant mechanical overhaul, in 2018. In his final three regular-season starts of 2020, however, Berríos changed something. He altered his arm angle slightly, raising it to a more overhand slot, and had his three highest average release points of the season in those starts. That matters, because when a pitcher releases the ball higher, with a higher arm angle, their fastball runs less to the arm side. Given Berríos’s style of delivery, a higher release point will also tend to lead to higher spin rates and more rising action, because the hurler reaches further through release, letting it off their fingertips more naturally. That’s exactly what happened at the end of 2020. Berríos had averaged under 2,190 RPM on his heater through mid-September, but that number rose to 2,291 in his September 25 start, when he had his highest single-game release point of the season, at 5.63 feet. In that game, he only got six non-contact strikes on 22 four-seam fastballs, but that was a promising game for that pitch. This spring, Berríos has only increased his emphasis on this skill. He’s had three starts tracked by Statcast, including Monday’s, and they are three of the four starts of his whole career in which he’s had the highest average release point. His spin rates are markedly higher. The results were more in line with the process on Monday, too: he got 11 non-contact strikes on 29 four-seamers. As I wrote earlier this month, Berríos came into the spring with three key mandates: to hit spots on the glove side of the plate with his four-seamer, to achieve the 12-to-6 shape he’s sought on his curveball, and to use his changeup more often against right-handed batters. He’s now doing all three. Continuing to get on top of his fastball and curve will only augment his efforts to sustain each of those skills, too, because obviously, a more overhand slot should yield a more vertical curve. That’s exactly what it’s done, and with Berríos executing better at the top of the zone because of his higher-spin heat, hitters are going to have to commit too soon to pick up the breaking ball. He’ll never have a classic overhand delivery, and that’s fine. Berríos’s deception and the tricky angles he creates by working from the third-base edge of the rubber make him a tough at-bat for opposing hitters. If he can keep his release point high, though, he’s going to hit his targets and miss bats more frequently, and he might make a leap to the next level in 2021.
