Building a Closer Through Outcomes

There are a sundry of middle/set-up relievers that can succeed in the closer role if given the opportunity. A few obvious: Wade Davis if something happens to Greg Holland… Wil Myers for James Shields and who?!; Ken Giles if the Phillies can somehow find a trade partner for the grundle-grabber; and Brad Boxberger if not Jake McGee. I assume David Robertson signs elsewhere and Dellin Betances steps in.

Lets’ look at potential closers using reliever outcomes. Here are the average contact and balls in play-related outcomes for all relievers that qualified and specifically relievers with 10+ saves:

Command: K% BB% K-BB% Ct% SwStr% Zn% F-Str%
AVG for RP w/ > 10 SV 0.27 0.07 0.19 0.75 0.12 0.46 0.63
SD for RP w/ > 10 SV 0.08 0.03 0.08 0.06 0.03 0.04 0.04
AVG for all qualified RP’s 0.22 0.09 0.14 0.77 0.11 0.45 0.60
SD for all qualified RP’s 0.07 0.03 0.07 0.05 0.03 0.04 0.05
Balls In Play: GB% FB% IFFB% GB/FB HR/FB LOB% BABIP
AVG for RP w/ > 10 SV 0.43 0.37 0.11 1.40 0.08 0.78 0.275
SD for RP w/ > 10 SV 0.11 0.10 0.04 1.02 0.05 0.08 0.042
AVG for all qualified RP’s 0.45 0.35 0.09 1.50 0.09 0.75 0.289
SD for all qualified RP’s 0.10 0.09 0.05 0.81 0.05 0.08 0.044

Our Filters: 

  • Contact-related outcomes: For K-BB%, Ct% and SwStr%, I filtered simply by the general relief pitcher averages. Everyone below average in these 3 categories was filtered out.
  • Command-related outcomes: For zone% and first-pitch-strike%, I used 1 standard deviation below average and 1.25 SD’s below average in BABIP as filters. 1.25 SD allowed me to omit only the relievers that had career BABIP’s higher than we would like to see for a closer or in general. I didn’t want to screen out Jenrry Mejia (1.24 SD below the mean) or Tim Stauffer (1.19 SD below), because there’s a possibility for BABIP regression.
  • Balls In Play-related outcomes: I was lax on the balls in play outcomes. I went with a 40% Grounder rate and 45% Flyball rate as my filters versus the averages that you see above because below average fly-rates don’t mean much in places like Tampa (where Boxberger is elite but below average in fly-rates); and above average grounder-rates don’t mean as much with atrocious defense behind you (hence Corey Kluber’s unlucky BABIP, which should have been closer to .299 per end-of-season xBABIP/Inside Edge data), but I digress.

Using these filters, we’re left with a robust list of above-average relievers beyond just closers (scroll down for the noted filters):

What happens if we use the command (K-BB%)/contact (Ct% and SwStr%) related averages for relievers with more than 10 saves this year? 

…We’re left with some elite closers and then a few interesting names.

Last year, Danny Farquhar (just missed the list this year) had a top 20 swinging-strike rate – about a percent better than Fernando Rodney, but it was masked by his BABIP and left-on-base rate that killed his surface stats (4.20 ERA vs. 2.40 xFIP). This year, he actually outperformed his xFIP with a 2.66 ERA. After an early season MASH Report on Rodney’s velocity, I eyed Farquhar. At least keep him in mind next year if anything does happen to Rodney.

Josh Edgin (Mets for those of you that don’t know) has a top 65 contact-rate sandwiched between Mark Melancon and Jake McGee and even induced grounders 50% of the time. He has a pretty extensive repertoire as well. In order of usage: Fourseamer, Slider, Curve, Change, Cutter and Sinker. According to his Brooks Player Card, he has great swing and miss rates on his Curve (>56%), Cutter (50%), Slider (>42%) and Sinker (33%). Even his Change approaches 30%. This isn’t the case on his Fastball, but at 93+ MPH, it induces a decent amount of grounders (1.8 GB/FB). Keep in mind he had late-season elbow issues which effected his velocity by a MPH or so, but he could be called upon to get Mejia out of a jam. I like him better than an unhealthy Bobby Parnell and Jeurys Familia from a command perspective for another year.

Zach Duke did his best Craig Kimbrel impression prior to the R2M monster hitting him in August. Prior to 8/1, Duke had a 34.9% K-rate and 27.3 K-BB%. Kimbrel ended the year with a 38.9% K-rate and 28.3 K-BB%. I think August and September brought him back to his realistic value (~2.50 ERA, 1.15 WHIP). It will be interesting to see who closes for the Brewers if they let Francisco Rodriguez go. Both Duke and Will Smith have above average (even for RP w/ 10+ saves) swing-and-miss. Will Smith should have additional command next year, but Zack Duke induces grounders better which I like in my closers/in Milwaukee. They also have Jonathan Broxton. The hierarchy seemed to be K-rod-Broxton-Smith late last season. If that’s the case, they should use Duke more (former starter) and in higher leverage situations. He was equally solid against both lefties (.258 wOBA) and righties (.262 wOBA).

Oliver Perez everybody! I thought I could filter him out by his splits being a lefty, but like 2012, he was more effective vs. righties (and faced 44 more of them). The D-backs have Addison Reed, up-and-comer Evan Marshall as well as Daniel Hudson caught touching 97 MPH so if not by outcomes or splits, we can filter Perez out by opportunity.

Darren O’Day and Andrew Miller is part of one dominating Baltimore bullpen – one that gets referenced by anyone who thinks the Orioles can beat the Tigers in the ALDS. Notice that Zach Britton didn’t make either of the above lists! He was filtered out by his below average K-BB% (13.70%). It’s his 75+% grounder rate (hence the 81+% left-on-base rate and .215 BABIP) that keeps him elite in Baltimore. The only concern you can have with O’Day is a fastball velocity almost 2 standard deviations below the mean for relievers, but his arm angle combined with that slider still induces a 30+% whiff-rate on both pitches. Miller’s slider though is a world apart from O’Day’s: only Pedro Strop, Will Smith, Jake Diekman, Greg Holland and Oliver Perez induces more whiffs than Miller’s 55% according to Baseball Prospectus’ Pitchf/x Leaderboards.  I doubt we’ll see a closer-transition next year in Baltimore unless Britton’s GB/FB ratio takes a drastic dive because his HR/FB ratio, which approached 18%, could be an issue.

An xBABIP review

On the last day of the season, @jeffwzimmerman provided me with Pitch xBABIP based on inside edge data. Let’s look at some of the bigger xBABIP differentials to keep in mind:

The last column depicts the z-score for BABIP differential. Francisco Rodriguez was expected to have a BABIP about 120 points above his actual BABIP. I highlighted (red/bad; green/good) the xBABIP z-scores as well so that you know whether or not to actually be concerned meaning sure Aaron Sanchez has the 5th biggest BABIP differential (over 2 standard deviations from the mean), but a .239 xBABIP is still utterly elite (3.34 SD’s from the mean). On the other side of the equation, it’s nice to see Evan Marshall, Carlos Martinez and Adam Ottavino (albeit in Colorado) with large BABIP differentials. Marshall and Martinez even have xBABIP’s over .5SD from the mean.

The last bit of fun

It was a very fun year to be doing bullpen reports for RotoGraphs. Aroldis Chapman broke the single-season strikeout rate of 2012 Craig Kimbrel (50.2%). He struck out 52.5% of the hitters he faced. Andrew Miller (42.6%) and Brad Boxberger (42.1%) also made the top 10 seasons ever. Dellin Betances (39.6%), Wade Davis (39.1%) and Craig Kimbrel (38.9%) made the top 20. Chapman’s swinging-strike% of 20% beat ’12 Kimbrel by .8%, but he couldn’t pass ’04 Lidge, ’03 Gagne, ’04 Gagne, ’02 Gagne or ’05 Lidge. Chapman, Miller, Doolittle, Boxberger, Betances (Wade Davis and Kenley Jansen close behind) all had historical, top 20 K-BB rates. Relievers dominate this list: only ’99 Pedro Martinez (#12), ’00 Pedro Martinez (#21), ’01 Randy Johnson (#27) and ’01 Pedro Martinez (#28) make it into the top 30, but it’s clear that we have a growing list of elite relievers.

From a fantasy perspective, thanks to 45+ saves totals out of Holland and Kimbrel, we had two relievers ranked in the top 20 pitchers. If Chapman didn’t miss time and Betances and Davis consumed the closer role, we would have had 3 others. Last year, Craig Kimbrel and his 4 wins, 50 saves, 98 SO’s, 1.21 ERA and .88 WHIP campaign made him the 3rd most valuable pitcher. This year with Kershaw, Cueto, Felix and Kluber, it would have taken even more.

If we combined the 3 more dominating performances exclusive of saves this year: Aroldis Chapman’s K-rate (52.5%) and saves total (36), Dellin Betances IP (90) – who was dominating in his own right, Wade Davis’ ERA (1.00) and Wins total (9) and Sean Doolittle’s WHIP (.73) – let’s call this guy Aroldellin Dooldavis, we would wind up with a 10.95 z-sum…just above Corey Kluber (10.72), but under Clayton Kershaw (13.74), Johnny Cueto (12.95) and Felix Hernandez (12.50). Even 50 saves wouldn’t have done the trick (12.43 z-sum):

Bullpen Report: September 20, 2014

The closer grid is updated below, but first up is your current rankings for 5×5 (W,SO,ERA,WHIP,SV), 6×6 (+HLD) and rate-stat (K/9, BB/9, HR/9, H/9, ERA) leagues using z-scores (rate stats adjusted by IP) for each category. It’s currently sorted by the standard 5×5 format. Scroll to the right for all of the individual z-scores in gray. I highlighted the relievers in green:

Here is yesterday morning’s review of Friday’s games including a grundle-grab reference, Edward Mujica probably sticking at closer, Drew Storen definitely sticking at closer, a White Sox closer swap rewarded with shakiness, and an update on Glen Glen Glen!

Bullpen Report: September 19, 2014

Phillies at Athletics: Ken Giles is the closer! This has already happened, but It’s my first BP Report since the Jonathan Papelbon grundle-grab, and I wanted to type it. I also wanted to type grundle-grab. Giles hasn’t had a save opportunity yet and his only 9th since was on 9/17. Sean Doolittle converted his 22nd save with 100% fastballs. Much of his success comes from throwing high, hard and historic which he did here:

I get two BP reports in a row so today i’ll focus a bit more on the game decisions and updates. Tomorrow I’ll get back to my normal per-pitch effect and component-comparison deal. I’ll also furnish an updated rankings list for your different league formats. I’m thinking the following:

5×5 (ERA,WHIP,W,K,SV)

6×6 (ERA,WHIP,W,K,SV + HOLDS)

5×5 Rate Stats Leagues (K/9, BB/9, HR/9, H/9, RA/9).

Any other formats? Shoot me a note in the comments section and maybe i’ll include it in tomorrow’s different rankings.

Indians at Twins: Glen Perkins has finally been shut down and Jared Burton will continue to consume closing responsibilities. While a MRI revealed no damage to his UCL (great news), he’ll be shutdown with a forearm strain and nerve irritation in his elbow. Strengthening and two months should do the trick. Burton got the win yesterday in 2/3 IP while Cody Allen blew his fourth save of the season through a Suzuki Double, Arcia Single and a botched double play ball.

Red Sox at Orioles: Edward Mujica got his 7th save of the season through three balls in play which is what we’ll continue to see from Mujica about 78% of the time (80% general contact-rate). Koji Uehara last pitched on 9/16 striking out the side. I just don’t see much motivation for them to make the swap at this point, but i’ll still swap him and Tazawa in the grid below. Zach Britton kept the game scoreless in the 9th and Darren O’Day continued his all or nothing month with a mistake and loss to David Ortiz. This says it all:

That red quadrilateral dead center? Yup, Ortiz capitalized.

Bullpen Report: September 13, 2014

A’s at M’s: Sean Doolittle is back, looked sharp and earned his 21st save the season. Since his last save on August 23rd, there was one lonely save by Eric O’Flaherty. The A’s went 6 and 14 over that timeframe. It was a big win for the A’s who kept the Mariners one game back from their Wildcard lead thanks in part to Doolittle’s clean return (1 IP, 1K), but thanks more in part to a Fernando Rodney implosion (1 IP, 4 straight walks in the top of the 10th). To date, using 50 IP as the qualifier, Sean Doolittle owns the 3rd best K%-BB% rate in the history of baseball, 36.2%, thanks in part to the 20th best K% ever (38.6%) and the  26th best BB% ever (2.4%). Incredible. Enjoy his high fastball in a time where not many others have this lethal high fastball and hitters focus with their chins down.

Astros at Angels: Angels keep winning: their 10th straight behind two Trout homers. Lefty specialist and deep bullpen option Joe Thatcher was activated from the DL. Austin Powers has forever ruined his last name for me: Margaret Thatcher naked on a cold day….Margaret Thatcher naked on a cold day! Huston Street earned save 14 for the Angels (38 in total). He gave up 1 hit, struck out 1 and looks as though he’s fine after being sidelined with a hamstring injury. Noncloser note: Jered Weaver continues to deceive. I strolled across this while preparing a 2015 Mets Rotation post…Jered Weaver owns the 9th best zone-contact rate for starters this year, and despite diminishing velocity, hitters are relatively swinging at much less stuff in the zone against him (14th best SP rate) confirming his continued deception.

Rays at Blue Jays: Usually I’m pointing to just how dominating Brad Boxberger has been, but perhaps he needs a little break despite only pitching in 4 of the last 8 days. It’s 2 appearances in a row now he’s given up a homer. He earned his 2nd loss of the season yesterday. With less than a month left of the season, if you’re in a saves-only league mayyybe it’s worth dropping Boxberger since Jake McGee is still the (very effective) closer. Casey Janssen confirmed that he’s still the Blue Jays’ closer earning himself save #23.

St. Louis Cardinals Bullpen: Rosenthal & Co.

There seems to be plenty to love about the Cardinals bullpen here in 2014, particularly from a fantasy standpoint. And we’re not just talking about saves here. Should your league count holds and use stats such as K/9 or HRA, then this is the pen you want to sift through on draft day. The arms are young, electric and should miss an awful lot of bats this season. Read the rest of this entry »


Fantasy MVP Greg Holland

While my array of fantasy baseball teams benefited from the likes of MVP candidates such as Chris Davis, Mike Trout, Jose Fernandez and Paul Goldschmidt, I am going to buck the trend and hand over the MVP honors to Kansas City Royals closer Greg Holland. The debate over the value of a closer is a recurring hot-button issue and, obviously, I sit on the side of the fence that preaches their importance. But even those who like to dismiss the position can’t deny how tremendous a value Holland was to those who owned him this year. Read the rest of this entry »


KC Royals Bullpen: Depth Chart Discussions

Obviously, if you talk to any legitimate stat junkie, they’d be able to tell you in a heartbeat, but ask any casual baseball fan which team bullpen was the most valuable to their team last year, and very few….probably none….would be able to tell you it was the Royals. With an overall WAR of 7.3 and such solid numbers like a 77.8-percent strand rate, an 8.5-percent HR/FB, a 3.17 ERA and a 8.58 K/9, the Royals pen was one of the team’s strongest assets. And this year probably won’t be much different as most of the components that made it so successful last year are back for more here in 2013. Read the rest of this entry »


Chicago White Sox Bullpen: Depth Chart Discussion

Much about the White Sox bullpen is more stable than it has been in years. They have a closer in place, they have a set of reliable set-up men, and they have respectable depth in the minors should they need it. However, with six viable starters for five slots, the Sox also have the option of moving Hector Santiago or Jose Quintana into the bullpen for this season.

Both will join the White Sox rotation soon enough, but if Santiago is the odd man out, he’ll likely stay with the major league club in a set-up role. This is unlikely to affect either of the Matts – Thorton and Lindstrom – but it could move Nate Jones from his set-up job back down to lower leverage middle relief.

The White Sox bullpen was right about league average last season, but with another year of experience for players like Addison Reed and the addition of Lindstrom, there’s a very real possibility that they’ll be a top-10 bullpen this season. Read the rest of this entry »
