  • The Twins Have Struck Gold With Brock Stewart


    Cody Pirkl

    The Twins bullpen has been around average by many measures, an impressive outcome considering their lack of additions this winter and several arms struggling. The emergence of Brock Stewart has been a big reason why.

    Brock Stewart has been a pleasant surprise. After dominating in St. Paul for just under nine innings, the right-hander got the call to the big leagues for the first time since 2019 and hasn’t missed a beat. He’s overcome an unsightly 15.5% BB rate with his 28.2% K rate in order to post a 1.06 ERA. He would have been a nice supporting piece to an already quality bullpen, but instead, he’s been a big reason it’s stayed afloat.

    It’s safe to say the Twins bullpen has not shaken out in the way they intended. After making no additions this offseason, things could be going worse, but they haven’t quite been up to the task of supporting what has been a stagnant offense. With little margin for error, 2022 breakout Griffin Jax has allowed a barrage of blown leads. Jorge Alcala has not rebounded from elbow surgery. Caleb Thielbar has missed time with injury. 2022 trade deadline acquisition Jorge Lopez has somehow been even more of a liability than he was down the stretch in 2022.

    All of this has led to Brock Stewart becoming an invaluable piece of the Twins late-game formula, as evidenced by his Win Probability Added being second-best in the bullpen. The Twins deserve credit for seeking out Stewart on a minor-league deal a year ago to rehab under their watch, but they’re fortunate that it’s turned out so well that Stewart has been one of their go-to relievers in 2023.

    Beyond the context of what Stewart has meant to this bullpen, his development is a major credit to him. A former top starting pitch prospect, he’s completely reinvented himself at the age of 31 after a career of struggles and injury. Stewart’s average fastball during his last MLB action was a modest 91.7. It currently sits at 97.2. In addition to the heater, Stewart has a five-pitch mix including a sinker, sweeper, cutter and changeup, all of which are inducing whiffs at a rate of over 35%. He has an entire arsenal of weapons.

    All of this to say, the Twins are fortunate to have Brock Stewart on call. There was little fanfare coming into the season, and he’s taken an opportunity and run with it. There’s no telling what the future holds for Stewart at 31, but the right-hander isn’t even arbitration eligible until 2025 so long as he can keep the magic going. Like they’ve done in the past, it appears the Twins have found a diamond in the rough. It’s hard to say where they’d be without Brock Stewart.

    This was a nice hit for the Twins, and with a couple of years of team control as well.  It is definitely “found” value.  Good job!

    The alternative way of writing this comment would be this. . . . Wow!  I can’t believe the Dodgers let this one get away, especially when they had a guy with an 80.96 ERA on their team.  No wonder they never have any decent pitching!  The team is always bad and this is why.  The entire management team surely must be fired.  

    See how silly that looks?

    Glad he's doing well - Good job.  BUT, I'm afraid now this will only support the FO belief that they don't need to invest in the pen because they can just find guys like this.  They obviously do, but not as often as they think they do.

    Typical story of SP prospect flames out, discovers how to pitch effectively as a reliever.

    He is off to to a good start, lets see if he can maintain it.

    It's definitely another one for the case files on "Why You Should Never Give Up on a Starter Until You've Given Him a Real Go as a Reliever". he's definitely a bit wild, but it's a lot easier to dodge around a walk or two as a high-velocity reliever than as a medium-low velocity starter.

    but he's also one of the reasons the Twins as an organization (and the Rays and a few others) tend to not want to spend on the bullpen: you can find guys like this. But props to the Twins for finding him and having some patience in the transition (he was not good last season) and for him in embracing the change in role to find success.

    We'll see if it's sustainable: the increased velocity certainly helps a lot, but he's also doing a much better job of keeping the ball in the park and has been less hittable as well, with a major uptick in K/9. If this is closer to who he is as a pitcher, he's going to be a useful bullpen piece.

    "A pleasant surprise" - Sure

    "Struck gold" - Let's pump the breaks on that and see how the season shakes out

    I do think they'd have a few more losses without him if they had to continue turning to guys like Pagan, Lopez and Jax in leverage spots when they were struggling. Small in the grand scheme of things but I think the season would look a bit different so far without Brock Stewart

    First of all, just want to state that I don't believe in spending a ton of $ on FA in regard to the pen. BUT, it's a tool to be used to help yourself. It seems like a 50/50 crapshoot most years as to whether you get a good pen arm or disappointing one. It's up to the FO, and the scouts, to try and guess right. And I DO believe they should have taken a shot this offseason to add depth, and to guard against Alcala being slow to get back. (I still have a lot of hope for Alcala, BTW). 

    I also believe you should be looking for  Stewart type EVERY SINGLE OFFSEASON. If not a couple of them. Quality Twins BP arms going back decades have been fliers like these. Current Thielbar is a great example. 

    I'm still a little worried about Stewart's BB rate and hope to see it come down. But he's been a real baseball godsend to the Twins. And let's take a moment to point out it looks like Jax has begun to right himself after some crazy stuff earlier in the season. Now, if they can get Lopez looking good again, with the improvement of Moran, thus pen can be legitimately 6 deep with room to add and roll through the St Paul candidates. 

    But like Stewart, they've gotten some really good work from De Leon as of late. Could he ALSO provide a big lift? Has his own injury filled and disappointing career suddenly trandlsformed in the Twins pen? I trust him less than Stewart right now, but he's looked pretty solid so far.

    I don't care where relievers come from, but you need to ensure you have plenty of good ones, and the Twins did the opposite.  Personally, I even felt Duran may not have been able to be counted on, necessarily, between his wonky arm and natural drop off.

    I think I listed every reliever and the reason why you couldn't count on him, and though I didn't put percentages with them getting hurt or going south, my point was that the Twins completely neglected a unit they needed to address and in no way were they going to have enough, even if a Brock Stewart type emerged.  I mean, Jorge Lopez is a head case (baseball-wise), and that should have been obvious from last year.  How do you count on Alcala? etc. etc.
