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):

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!

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.

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.

–Tony Watson collected the rare two-inning, six-out save this afternoon in a Pirates 5-3 victory over the Reds. With Bucs closer Jason Grilli and setup man Mark Melancon unavailable out of the pen today, Watson earned a second inning of work en route to his second save of the season. The southpaw dished an impressive eighth-inning, working through the heart of the Reds’ order — Joey Votto, Brandon Phillips and Jay Bruce — prior to cleaning up the last of Cincy’s bats in the last half of the ninth to seal the deal. While Watson may not earn a ton of saves this season, he’s a valuable asset in holds leagues. The lanky lefty’s ratios aren’t exactly sexy, but he’s notched 11 holds on the season and owns a reasonable 19.7% K% on the year.

• Sean Burnett entered in the ninth-inning of the Nationals’ contest last evening versus the Metropolitans with a save on the line. The lefty yielded two hits in two-thirds of an inning before Davey Johnson asked right-hander, and former closer, Drew Storen to get the last out with runners on first and third. Storen did just that — inducing a David Murphy fly ball out to center field to earn his second save of the season.

Despite the save from Drew Storen, Tyler Clippard’s job as closer should remain secure in the nation’s capital for the remainder of 2012. Clippard has experienced some recent hiccups — allowing five earned runs in his last five outings — but his absence may have simply been a case of the Nationals getting the “goggled one” some rest after he made appearances in four of the previous five nights. On the season, Clippard is 31-of-34 in save opportunities with a 3.18 ERA (4.03 xFIP) and a 2.89 K/BB.

To say that the closing situation in baseball has been a disaster this season would be a grave understatement.  Of the 30 teams this year, 18 teams have had to make changes and/or adjustments due to injury or an outright lack of success.  Some of the changes have been temporary while others have seen multiple relievers moved in and out of the role causing fantasy owners to spend far too much time playing the waiver wire in search of consistent saves.  But what happens once the dust settles and there’s almost no more turnover?  What happens when you can’t find saves on the waiver wire and you’re in need?  The trade market can be a very unforgiving place to shop.

Here are the results from this week’s groundbreaking editions of ADP Crowdsourcing, as it was our first time trying out a closer, a player who missed all of 2010, and a top-25 talent.

Joe Nathan
My vote: 8
Average: 11
Median: 11
Std Dev: 4

So, none of us really have much of an idea where Nathan will go, do we? If there’s one thing we can all agree on, it’s that Nathan would go somewhere around the seventh round if he were healthy, maybe even earlier if a closer run gets going. But, we just don’t know how he’ll respond coming back from his injury, at least not yet. If we did this with Nathan in spring training, when we have some sort of read on his status, our results would probably be very different. If he looks healthy, an 11th round selection is obviously a steal. But if he’s healthy, you aren’t going to get him in the 11th, are you? Just because of the inherent risk involved, I’m probably not going to draft Nathan this year, but if I did, it’d be in the 10-12 range.

Alex Rodriguez
My vote: 2
Average: 2.21
Median: 2
Std Dev: 1.05

Reader “Jason B” brought up a very good point in the comments on Wednesday, wondering why I didn’t group the selections for A-Rod by pick number rather than round number. I probably should have, but I did want to see how the format worked with an early round talent. I’ll probably try an early round guy soon, and will try out pick number instead of round. But, the old method held up fine, showing that A-Rod will likely go in the early second round, and he probably won’t fall further than the early third. I think he’s a great 1-2 turn candidate this year, and I’d be more than happy to take him there.

In today’s edition of ADP Crowdsourcing, I take another suggestion from reader Dale. Someone get this man a free hat, or another gift of some kind! Results from last week’s round of voting will be up at noon (eastern) today, so don’t forget to check that out.

Joe Nathan has long been a fantasy stud, because he can give you close to 100 strikeouts a year from the relief pitcher position. Plus, he’s given you 35+ saves in every year he’s active for the Twins, and his low ERA combined with high innings count can make a huge impact on your total pitching numbers, compared to what some other closers can do for you.

If I had to complain about Nathan, I’d moan about how he doesn’t get enough ground balls, but he’s still likely to be above the 40% mark in that area, so it’s hard to get worked up about it. I’d also mention that Nathan’s velocity was slipping a bit even before his injury, but he was still able to get batters to swing and miss at a high rate. Again, nothing to really complain about.

Nathan’s case is going to be a very interesting test, because he didn’t even see the field during the 2010 campaign, and this will be the first time we’ve tried a closer. I’m expecting a fairly large deviation on this one. Will Nathan still be viewed as a top flight closer on a good team, or will owners be a little skittish? That’s for you to decide.

Below is a link to the voting form, and please read the wording carefully. This is not where you would draft him, but where you think he’ll be drafted in most leagues. For the voting, we’re assuming a 12-team standard league, using 5×5 scoring.

The news came down the pipe this morning that Joe Nathan has a torn Ulnar Collateral Ligament and is, in all likelihood, headed for Tommy John surgery. No pitchers in recent memory have rehabbed through a torn UCL. A moment of silence for Nathan’s 2010 season, and for all of the keeper league owners that were happy with their elite closer.

Now let’s have some fun with rampant closer speculation. The front-runner has to be Jon Rauch because of his mythical ‘experience in the role.’ Yes, because he closed for 40 innings in the National League, he’ll probably be the front runner to assume the mantle in Minnesota. Then again, one has to be concerned with his strikeout rate, which peaked in 2006 (8.47), recovered in 2008 (8.29) and dropped off a table last year in Arizona (6.30 overall). In general, he offers some nice strikeout ability (though not plus for a closer) and an above-average walk rate (2.89 career, 3.46 ’09 ML average).

On the other hand, there’s been some change in his mix as he’s aged, and it doesn’t seem to be good news. He’s using his fastball less every year (down to 52.8% from 67.9% in 2006) and replacing it with his curveball (up from 3.3% to 15.5% last year). The problem? His fastball has been worth 17.1 runs by linear weights over his career, His curveball? -1.3. Yeah, where is that fastball going?

Could the Twins instead turn to a man with a funky delivery that has his own blog and a penchant for juicing? What about Pat Neshek? He owns a sparkling 10.56 K/9 for his career, a decent 2.76 BB/9, and despite slight gopherball problems (1.12 HR/9 career), has a sparkling WHIP (0.96). He’s coming off TJ surgery of his own, but has pitched live ball in Spring Training (2 innings, 2 Ks and 1 hit if you must know). There is a whiff of Brad Ziegler about him, but here are his splits against lefties, from our very own splits pages: 8.59 K/9, 3.68 BB/9, 1.16 WHIP (good), 55.9% FB, 12.1% HR/FB, 1.64 HR/9, 4.70 xFIP (bad). This is all against 185 total lefty batters faced… this sample is not big enough to say definitively that he cannot handle lefties. This book is not closed. And since it is such a fun read, there’s at least one fantasy analyst that is banging the drum for Neshek to take over the closer’s role for the year.

What about Matt Guerrier? What about him? With a below-average 6.01 career K/9, and no corresponding excellent ground ball rate (45.5% career) he’s squarely third on this list. His .222 BABIP last year will surely regress and the Twins will once again have the okay guy they’ve always had. No closer here, despite last year’s seemingly excellent numbers.

One last note – the possibility that the closer comes from outside the organization is reasonably high. The Cubs inquired with the Jays about Jason Frasor, and because that team is rebuilding, it seems that maybe also Scott Downs might be available. Anthony Castrovince, the Cleveland Indians reporter for MLB.com, speculated on Twitter about Kerry Wood being moved to the Twinkies. These options may all be more palatable to a Twins team that wants to compete in their new stadium. Hey, they all have ‘experience in the role.’
