    Three Things the Twins Need to Do to Compete: Part One: Fix the Pen


    Thrylos

    At first read, the title of this series sounds very much like A Midsummer Night's Dream: Do I dare suggest that the team that went from 99 to 96 to 96 to 92 losses the past five seasons needs to do only three things to compete? The next number to that Arithmetic Progression up there is between 88 and 92 and that is not competing by any means. Let me explain my train of thought here, before the nice kind people in white come and take me to warmer climes:

    First: In order to make significant, measurable and effective change, you cannot focus on changing 20 things. Too many balls in the air, some will drop. Focusing of a few things that you can change and make an effort to do so, is much more effective. Second: I do believe that with the changes this off-season, the Twins removed a huge barrier to their success: Breaking ties with Gardernhire, Anderson, Ulger and Steinbrenner (even though they did not go far enough in my opinion, but this is another matter) is the equivalent of starting the seasons with, at least, plus five wins.

    So that next number in that loss progression looks more between 83 and 87. So those three things that need to be done, if done correctly and effectively, will be enough to give the Twins an extra five to seven wins, putting that total loss range to 76-82 and that is not a losing record. The top number of that range (86-76) is close to a wild-card number and, if the Twins get there, they likely will compete for the title in a weakened and more balanced Division.

    The first thing they need to do to get there is to fix their bullpen. And I hope that they know that this was a huge problem in 2014; as a matter of fact a bigger problem than the rotation. I touched it a bit here, suggesting that they spend some more money and get another late inning reliever. Even though this bird has flown already, there are similar possibilities, especially in a trade, outside the organization. But there are potentially intriguing possibilities inside the organization. Let's frame the problem first, and then let's look at what they have at hand, and explore potential solutions.

    The Problem:

    In 2014, the Twins' bullpen was bad; how bad? It ranked 29th in the majors in both xFIP (4.18) and SIERA (3.84). And those are numbers that are, a. fielding independent, so Gardy's Catchers at the Outfield are not factored in, and b. reflect the actual talent of pitchers and not external parameters, thus really measuring how good the staff is in a vaccum (as much as one can have.) So why was the Twins' pen was one better than the worst in the majors? Let's do some root cause analysis: Here are some other numbers for the pen, and their rank in the majors: K/9: 6.66 (30th), K%: 17.3 (30th), SwStr%: 9.2% (30th), GB%: 40.1 (27th), FBv: 91.5 (27th), Contact% 80.9 (1st). So, in other words, the Twins pen: Had the worst strikeout rate in the majors, the worst swing strike percentage in the majors, the third from the bottom ground ball rate in the majors, the third from the bottom fastball velocity in the majors and the most contact rate in the majors. However, it could had been worse: The Twins' pen ranked 15th in BABIP (so they were not particularly unlucky) and 23rd in HR/FB. So in simple terms, the 2014 Twins' pen:

    • Could not induce swings and misses or strikeouts
    • Put the ball in play more than any other pen
    • And the put the ball in play with the third worst velocity in the majors
    • When the ball was in play was the least on the ground than all but 3 other teams
    • Thankfully, they were lucky enough that their fly balls translated to home runs at a rate less than league average and batted balls (other than home runs) were hits at a league average rate.

    What they have at hand:

    To see what they have at hand, let's create an imaginary construct called the league average reliever. So here are the numbers (and I am focusing on the Twins' weaknesses here) of the league average reliever: xFIP: 3.67, SIERA: 3.34 (those 2 are pretty much equivalent, they correlate with 92% coefficient, so I will be focusing on SIERA only for simplicities' sake), K%: 22.2, Fastball velocity (FBv): 92.5, Swinging Strike% (SwStr%) : 10.5.

    Here are how the current Twins' bullpen candidates (and "locks") performed in those categories in 2014. If they are equal or better than the average major league pitcher, that number is in bold. For players mostly in the minors, I am including their K% in the minors (in parenthesis). The other numbers are not available.

    Pitcher SIERA K% SwStr% Fbv

    LHP

    Glen Perkins 2.62 25.4 11.2 93.4

    Brian Duensing 4.29 14.4 8.6 91.1

    Logan Darnell 3.55 19.6 (18.1) 9.9 89.8

    Aaron Thompson 3.8 19.4 (22.5) 10.8 89.1

    Caleb Thielbar 4.06 17 6.2 89.1

    Tommy Milone 4.57 14.5 7.3 86.6

    Ryan O'Rourke NA (28.7)

    RHP

    Lester Oliveros 4.62 18.5 (35.4) 9.8 93.7

    Ryan Pressly 4.18 11.5 (24.6) 8.3 93.3

    Blaine Boyer 3.45 18.1 (23.5) 9.8 93

    Michael Tonkin 3.56 18.4 (24.2) 8.4 92.8

    Casey Fien 3.43 19.6 10.4 92.3

    Trevor May 4.2 20.7 (23.5) 9.4 91.9 (*)

    Stephen Pryor 6.94 12.5 (27.2) 5.7 91.7 (*)

    Tim Stauffer 3.09 24.5 10.9 91.1

    A.J. Achter 5.11 10.2 (24.6) 8.3 90.2

    J.R. Graham NA (15.7)

    Mark Hamburger NA (16)

    So, in other words, the Twins now have only 2 pitchers who were above the proverbial average pitcher in 2014: Glen Perkins and Tim Stauffer. In a seven men bullpen, this is not very encouraging. For the time being, let's pen in Perkins and Stauffer and look for 5 more names, at least one of whom has to be a lefty. I assume that starting pitching prospects like Alex Meyer, Taylor Rogers, Tyler Duffey & Jason Wheeler, will be in AAA if they do not make the rotation, so these 5 are out of this discussion.

    One wild-card is Mike Pelfrey. I believe that he has the stuff to make an excellent late-inning reliever, and make the jump that Glen Perkins and Joe Nathan did before him. However, Pelfrey has been a better starter than either Perkins or Nathan, so his ceiling as a late innings reliever is higher than both. Pelfrey has pitched in two games in relief (for the Mets in 2007) thus if that transition happens, it should happen as soon as possible, to be able to pitch on consecutive days when the season starts. Why do I think he can be a good late innings reliever? His fastball is explosive when healthy and is his primary weapon. As a starter, he has to mix his pitches. As a reliever, his 92.5 mph fastball, can easily gain 3-4 more miles an hour. His curve ball is a good complementary offering and he would have the luxury to drop his non-successful slider and cutter and just occasionally mix his less than stellar split finger change. This makes 3.

    As far as righties go, the Twins will likely take Casey Fien north (and hopefully not use him in high leverage situations, because he is below average in all of the above categories, and he is one of the major drivers of the low GB%, since his is only 32.1.) Fien would not be my choice. I would rather see what Trevor May can do as a reliever. Similar discussion as with Pelfrey: His 91.9 mph FB average will get to the mid-90s as a reliever, plus he had the second best K% of the group in the majors and a respectable SwStr% (mostly as a starter, and will get better as a reliever.) And the cherry on top is that he led the 2014 Twins' pen with 2.0 Ground Balls per Fly Ball and a 57.1% GB%. May projects as an above average reliever. This makes 4.

    Need a lefty, and from that group, I'd go with Brian Duensing, and not because he is the most veteran. Brian Duensing (like Glen Perkins) regressed a bit in 2014, mainly losing about 1 mph velocity on his fastball and losing effectiveness in his slider. That translated to a K% drop from 20.9% to 14.4% and a SwStr% drop from 10.5% to 8.6%. That said, he had the highest GB% of all the lefties in the Twins' pen (45.7%) and has by far the highest velocity of the lefties left in the list. As far as offerings go, I think that Duensing has too many pitches. Losing either the slider or the curve (both have been inconsistent) and focusing on one, plus regaining his 2013 form (which was at or above the average pitcher's) will do wonders for the Twins. I hope that the new pitching coach will help in these regards.

    This makes 5 which leaves a lot of candidates for 2 spots. I think that the Twins will need someone who can fulfill the Anthony Swarzak role, but all of the above have been starting pitchers and there is flexibility, which means that if, for example, Tommy Milone loses out for the fifth starter job, he does not have to be the long man in the Twins' pen. Having a long man by committee, might actually be an interesting approach. The most intriguing names above for me for the last two spots are Aaron Thomson, Stephen Pryor, J.R. Graham, Ryan Pressly and Blaine Boyer. Pryor used to throw fastballs in the high 90s (career average 96.4) but velocity slipped due to injuries last season. Very similar situation with the Rule 5 pick, J.R. Graham and their former Rule 5 pick Ryan Pressly. Blaine Boyer is the veteran in the group, with a good track record and might make the team. As far as another lefty, Thomson is ahead of Thielbar (who in addition to being below average in every respect, has a 31.8% GB%).

    Should the Twins go out and target a "known quantity" like Jonathan Papelbon (2.86 SIERA, 24.3 K%, 12.1 SwStr%, 91.2 mph, 41.9 GB%) in a trade? I think that it would definitely help, but putting Pelfrey and May in the pen might work equally well. I think that the bones are there. Perkins and Duensing should rebound from regressive seasons, Stauffer was a good acquisition, if you break down the numbers, and they will find 2-3 more relievers. But they have to take the best 7 north, which means that they might have to make tough choices regarding below average extreme fly ball pitchers like Fien and Thielbar, even though there might be the belief that they should still be under scholarship.

    I think you're being a little too hard on Fien. In terms of SIERA, SwStr% and FBv he was only negligibly below average, and Fangraphs is projecting him to have 22.2 K% in 2015. Now, if he's your 8th-inning guy, that's not a good bullpen. But it certainly doesn't hurt to have an essentially league-average arm get a spot somewhere. It's the significantly below-average guys that we want to avoid. And I think May is more valuable as a starter.

     

    Do you have separate stats on LHPs? I wonder if their average FBv might be a bit lower.

    Fien has a very high fly ball rate at 49%. He needs a strikeout rate closer to 30% or at least north of 25% to be effective with that fly ball rate. Unless he has a role where he comes in with no one on base, he is a disaster waiting to happen from the pen.

     

    His strikeout rate dropped from 29.9 to 19.6 last year and it wasn't just the end of the year. It was around 20 all year. He needs to be closer to his 2013 rate than his 2014 to be a useful reliever.

    I hope the entire bullpen outside of Perkins are fighting for a job. I hope the Twins are willing to let Duensing and Stauffer go as soon as a younger player shows they are ready. If that is opening day, so much the better for the Twins.

    If Stauffer's showing last night was any indication, yikes! He was shelled. 

    I was at work, so I had the game reduced and was listening more than watching, but my impression is that he was working things.  I can't really point to anything specific about the pitches he was throwing or anything like that.  All I can say is that it "felt" like he was throwing a bullpen more than a pitcher actively trying to prevent runs.

    I can't get my head around a lot of Sabermetrics stuff, but I can visualize "IS%" (percentage of inherited runners scored). The Twins relief staff in 2014 allowed 31% of inherited runners to score (league average 28%), which was 22nd in the entire MLB.

    That's... surprising for a bullpen that allowed so many balls in play (29th in xFIP). Seems like they may be due for regression in that area.

    If Stauffer's showing last night was any indication, yikes! He was shelled.

     

    For 2 million dollars you get a decline phase veteran reliever that was used in low leverage situations with poor performance outside of Petco park. Good set up men cost north of 5 million on the open market.

     

    Only the eyes of the Twins staff should be able able to gauge whether to be concerned on his performance earlier this week. There is good reason for anyone to be concerned that the Twins see him as a late inning reliever based on his performance outside of Petco and age. There could not have been many teams competing for his service this winter.

    Article had detailed analysis and improving the bullpen is a must.  The extension of this goal is to stop relying on castoffs from other teams (paying-up for proven quality is different) has to stop.  Develop your own RPs, so there is an abundance of young, fresh, and strong arms rather than hoping for "...an extra 3-5 mph because so-and-so moves to the bullpen, thus permitting him to [succeed]...".  The youth movement, with sufficient quality (and yes those very useful options) would permit a reduction to 12 and even 11 total pitchers on the active roster freeing-up a spot for an extra position player.  Matchups?  They work both ways (pitching vs hitting) except the hitting team gets the final move.

    I think the Twins have a solid mixture of solid arms for the pen.  Thy should be around league average.  Throughout the year the Twins will start to bring up and install ore power arms.  I am more concerned how the bullpen looks at the end of the season then at the beginning.  kind of like how the offense changed over last season.  Fien is a solid 7th inning pitcher, Perkins is fine, Burdi is on the way, Pelfry could be a darkhorse pitcher who exceeds expectation here.

     

    Deunsing, Thielbar, and Stauffer/Pressley? are likely place holders and gone next offseason

     

    I am not as worried about the pen ...outside of the OF defense, CF, 5thstarter, and maybe the 7th bullpen guy, I am pretty confident in this team winning 85 games this season. 

    At some point the Twins need to see how Pelfrey does when he comes in with runners on base. His performance as a starter with runners on base was significantly worse than with the bases empty. It contributed to ERAs that were worse than his FIPs.

     

    It could be his slowed pace with runners on. It could be a drop in performance when pitching from the stretch.

     

    They also need to see how his arm bounces back and whether he can pitch on back to back days without loss in velocity or command.

     

    I am not sure that can all be assessed in spring but as soon as they determine he is not a starter they need to be putting him in situations they expect him to see as a reliever.

    At some point the Twins need to see how Pelfrey does when he comes in with runners on base.

    Or just let him start a game. Events will unfold. :)

     

    / I'm actually hoping/rooting/expecting Pelf to do well enough to make the 5th starter decision difficult. Today's outing was not much in line with that however.

    I think there's a tacit assumption that the article is discussing Opening Day, and therefore who is on the 40-man roster right now. Adding Burdi now would mean dropping somebody - which wouldn't be the end of the world, but it's not going to happen like that so why factor it in.

     

    The wild card for me is that currently the 40-man has 22 pitchers and 18 position players. That suggests to me there is room for a trade of some type in late March. It could be a minor swap to get rid of perceived dead wood (*cough*Nolasco*cough*), or it could be big. A big trade could change every discussion here, so you can only go with what you know now, but it's still there in the background.

     

    True.   I too would like to see a trade of Nolasco and outright DFA of Pelfrey to free up rotation spots for Meyer and May.  But judging how Ryan and Molitor have been talking up Mike and Ricky i don't think it will happen.  The Twins are making a mistake by allowing May & Meyer to grow old in the minors (both are 25 now).

    "... old in the minors..."  One could add that to several others, especially those that are projected to be RPs. Given their available options they could yo-yothese guys for three years to challenge them and see who suceeds and who fails. 

    A really great article Thry. And I can't really put finger to keyboard here and disagree with you.  And yet...we have disagreed a bit on this topic over the last couple of years.

     

    I absolutely agree that THIS is the year where the bullpen gets a revamp. It's time. And I'm not so sure that the bullpen that begins the season is the bullpen that ends it. I think Burdi, amongst a couple others, could make things really interesting.

     

    But I think where we disagree   is that the bullpen wasn't always as bad as advertised the past couple of seasons. Were I not too busy, tired and lazy, LOL, I would bet real money I could prove the Twins pen the past few seasons was much better May thru July/August than the final numbers suggest. A worn out bullpen will begin to shatter at some point.

     

    I agree the bullpen needs to be addressed. I think we have a lot of really talented arms that need, and are worthy, of opportunity. I also think by mid season there will be another 1-3+ bullpen arms ready to audition. The question is, will Molitor and Ryan and staff make room?

     

    Even before that, will they make room for the guys they already have on roster? Because while I feel the entire Twins organization wants to move forward, Im still worried they might stick with veteran/contract pitchers for the reason of.........?

     

    Go ahead and give Graham a shot if you think he's for real. Give Stauffer his $2M shot.

     

    But to me, don't you dare ignore Tonkin, Oliveros and others just because.
