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:

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):

Any day now, Zach Sanders (@zvsanders) will come out with his end-of-season FAVRz/Fantasy Rankings. Look out for them.

For this post, I will provide three sets of rankings using that same approach (summed up z-scores) for our end-of-season “Bullpen Report: Expected Fantasy Rankings”. The Bullpen Report team should follow up with role reports for each division in the coming weeks as well.

The first set of rankings you will find almost anywhere: on the fantasy sites that you use, via player-raters, etc. It’s the standard 5×5 fantasy value (Wins, ERA, WHIP, SO and Saves). The second grid will be for 6×6 leagues (addition of Holds). The last grid will be for 5×5 and 6×6 leagues, but instead of standard ERA and WHIP, we’ll look at rankings if you were to use expected ERA (via SIERA) and adjusted (adj)WHIP through BABIP differential: I will explain below.

1) 5×5 Rankings (Wins, ERA, WHIP, SO and Saves) – actual 5×5 value in column 4; expected 5×5 value in column 5:

First, the ?’s.

Second, the historical K%’s.

And of course, the Grid…

1) The ?’s

Angels at Twins: Glen Perkins has a sore neck (received a MRI after tingling, but there was no structural damage). Ron Gardy said he should be back within a few a days so I wouldn’t jump to the waiver wire for anyone. We didn’t get a chance to see who would have had the opportunity to close out the games for the Twins tonight. While it was presumably Jared Burton, he received the loss, getting beat by a Albert Pujols double after a single (Cron) and walk (Trout) and then Anthony Swarzak let in the inherited runner.  Huston Street earned save #37. That’s 3 straight appearances for Street and he could potentially use the day off tomorrow. He only has 2 k’s in through his last 5 appearances, and his win yesterday came from a blown save. He induced only 1 whiff from 6 swings tonight.

Astros at Athletics: Sean Doolittle had a successful bullpen session today and should be activated next week. Until then, it’s still Eric O’Flaherty closing out games. David Wiers called O’Flaherty a wild-card for the closing role prior to the season and the ground ball rate (58+%) and weak contact (.213 BABIP) holds true. Tonight, Luke Gregerson pitched a scoreless 9th for the win. Heck, if you’re own a hold league, why not own the entire Oakland bullpen next year?

Chad Qualls remains under the weather with a case of the shaky qualls. He let both of Scott Feldman’s inherited runners score and then gave up the winning single to blow a 3-1 lead in the bottom of the 9th. I would think and hope that Tony Sipp is next up  for the closing role. Other than a shellacking on 8/25 (4BB and 4 ER without recording an out), he’s been lights out since 8/12 (12 K’s, 0 BB’s and only 1 hit). Yesterday, he struck out 4 of 7 batters. I’d like to see him with the gig.

Reds at Pirates: The Josh Harrison show included a triple in the bottom of the 8th that gave the Pirates the lead for a Mark Melancon save (#25).

• White Sox at Yankees: David Robertson furnished save #34. D-Rob has only blown 2 saves all year this year and has done an awfully good job displacing Mariano Rivera. In fact, as a closer, Mariano Rivera never reached a 30% K-Rate and his career contact rate was 79.7%. D-Rob has a sub-70% contact rate this year and could be even better next year assuming the luck stats (BABIP based on his inflated line drive rate this year; HR/FB and LOB%) all take a step forward next year. It will be interesting to see where D-Rob lands next year considering he deserves a big payday and the Yankees still have another dominate K%(39.9%)/Contact%(70%) reliever in Dellin Betances. D-Rob got the 10th best K%-BB% in baseball right now: 28.5% tied with Koji Uehara.
• Rays at Blue Jays: Casey Janssen has offset an awful K-rate with the best BB-rate of his career, but he walked Wil Myers tonight to start the 9th and blew a save after a couple of singles. Brad Boxberger pulls an Armando Benitez and gives up a 2R-HR to Dioner Navarro and a double to Colby Rasmus. We were getting pretty spoiled with Boxberger: 8 scoreless innings since August 10th with a 13:1 K:BB ratio and only 3 hits. Between Koji Uehara yesterday as well as Boxberger and Ken Giles today, the R2M (Regression to the Means) Monster hit me hard this weekend.

For my first Bullpen Report, I wanted to provide additional value so I blasted “Enter Sandman” and sprinted toward my office to write this.

Below the report of yesterday’s games, you will find rankings for 5×5 (W,ERA,WHIP,K,SV) and 6×6 (+Holds) leagues based on Zach Sander’s FVARz approach. For reference, I used 108 active Pitchers = 9 P x 12 teams and 25 IP as a qualifier. Why 25? I didn’t want to leave Ken Giles off the list.

But there’s more. In addition to their fantasy value, I’ve z-scored outcomes on the plate appearance level to depict pitcher skill (K%-BB%, Ct%, GB/FB, F-Str%, and IFFB% weighed by their correlations to ERA) and luck (BABIP, HR/FB and LOB% weighed by their correlations to ERA) thus far this season. To back up the top 20 relievers ranked by my “Skill” Score, I also furnished grids on their pitch outcomes, which depicts how well their individual pitches induce whiffs and grounders vs. flies.

-A lackluster start to the season by Detroit’s closer-by-committee situation lead the Tigers down a familiar path on Thursday. The American League Central favorites re-signed their former closer, Jose Valverde, to a minor league contract with the option to opt out by May 5th if he’s not called up to the Majors. The 35 year-old veteran is clearly not the long-term solution in Motown, but could serve as a band-aid until Phil Coke, Al Alburquerque or Joaquin Benoit decide to grab ahold of the ninth inning — or until Bruce Rondon is deemed ready for the role.

With the signing — and if he gets the call — Valverde would have the third most career saves among active, non-injured relievers. Entering today, Valverde’s 277 saves would place him behind only future Hall of Famer Mariano Rivera (608) and Joe Nathan (298) among those expected to pitch in ‘13.

• Tyler Clippard closed the door on the Dodgers in the first half of a double-dipper this afternoon, earning his 32nd save in 35 chances this season. Clippard gave up a one-out hit to Mark Ellis, but needed just 14 pitches to induce three fly ball outs in the ninth to seal the deal. Davey Johnson called Clippard to the hill again in the second half of the double header — but gave up a lead-off moonshot to Matt Kemp — and took the loss, his fifth on the year.

• After quittin’ time on Wednesday, Aroldis Chapman saved his 23rd consecutive game — tying a franchise record held by John Franco (1988) and Rob Dibble (1991) — to up his successful save tally to 31 on the year. Chapman continues to make his case for Cy Young consideration, as he now holds a 1.31 ERA and a 16.26 K/9 (7.47 K/BB) while holding opposing batters to a .138 average.

• Steve Cishek of the Miami Marlins’ nailed down his fifth save of the season tonight in a 4-2 victory over the Atlanta Braves. Cishek faced the minimum three batters — and although he surrendered a leadoff walk to Michael Bourn — needed just 12 pitches to get out of the inning. Tonight’s save was the fourth consecutive conversion since July 6th for the 6-6 right-hander who now owns a 1.86 ERA (3.97 xFIP) and a 2.1 K/BB. For those chasing saves, consider Cishek who is available in 69 percent of Yahoo! leagues.

Heath Bell, who hasn’t entered a game in a save situation since July 8th, appeared in the eighth inning of tonight’s game and earned his fourth hold of the year.
