Potential Closer Changes

Because fantasy owners are always chasing the save, I’ve identified a few situations where a setup man is pitching better than the closer. These setup men can be added both as a prospective source of saves and as a minor boost in the ratio categories and strikeouts. If you have a rotating spot at the bottom of your roster, these guys are candidates to fill it. Read the rest of this entry »


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 6th, 2014

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.

Bullpen Report: May 30, 2013

Bobby Parnell notched his ninth save of the year in a 3-1 Mets victory over the Yankees tonight. For the Metropolitans, the win surprisingly sealed a series sweep against their crosstown rivals, providing them with some momentum as they head back into divisional play against the Marlins, Nationals and the Marlins again over the course of the next two weeks. For Parnell, it was his third consecutive save and the third outing in-a-row without surrendering a hit. The lanky right-hander whiffed one-of-three batters this evening, bringing his whiff rate to 25% on the season. The current 25% K% is actually higher than he’s had in the past two seasons — 23.9% and 21.2% respectively — despite missing fewer bats (8.6% SwStr%) than he has over that same time (9.8% SwStr% in ‘11, 10.1% SwStr% in ‘12). The previous data leads me to believe that Parnell’s strikeout rate could continue to rise if his ability to miss bats regresses toward his career 9.6% SwStr%. His recent success parlayed with the news that Frank Francisco was transferred to the 60-day disabled list today with continued elbow issues further proves that Parnell’s grip on the closer’s role in Flushing continues to get stronger.

Bullpen Report: July 5, 2012

• Minnesota Twins’ closer, Matt Capps, is scheduled to toss his first bullpen session this weekend since hitting the disabled list on June 24th with inflammation in his right shoulder. If Capps feels well after the bullpen session, he will head to Class-A Fort Myers to pitch an inning of rehab with the hopes of returning to the Twins at the conclusion of the All-Star Break.

Bullpen Report: June 27, 2012

• Besides Giants’ fans and those in holds leagues, has anyone noticed the season Sergio Romo is having? The guy has been filthy. Tonight he earned his fourth handshake of the season while lowering his ERA to 0.83. Romo is inducing swings-and-misses at an astronomical rate (18.7 SwStr%) which leads us to believe his 12.39 K/9 is more than real. Although Romo has only accumulated 21.2 innings on the bump, he’s sporting a FIP (1.82), xFIP (1.89) and SIERA (1.65) that indicate we may see a slight regression, but we’re likely going to see more of the same. At this point, Romo is owned in holds leagues and in shallower leagues with saves chasers. If by chance he’s available, I’d consider making the add to get a weekly boost from his ERA (0.83), WHIP (0.79) and the aforementioned strikeouts.

Pick Six Value Picks: Starters and Relievers

To close out our series of looks at the values of players in ottoneu Pick Six, we look today at pitchers.  As before, the numbers below are based on weighted averages of THT’s Oliver and BPro’s PECOTA (more weight to Oliver b/c it includes this season’s data).  The numbers are FP (FanGraphs Points per IP), though keep in mind that for starters this number is divided by four to keep starters from being the only thing that matters in pick six.

Starting Pitchers

Elite Five (they cost a fortune, but they’re worth it)

Tim Lincecum, 5.33 FP/IP, $48
Josh Johnson, 5.21 FP/IP, $38
Felix Hernandez, 5.04 FP/IP, $49
Cliff Lee, 5.04 FP/IP, $43
Roy Halladay, 5.01 FP/IP, $52

Johnson’s injury risk has kept his value down in traditional ottoneu, but when he’s healthy (currently has shoulder ouchie), he’s the best value of this group.  But you can’t go wrong here: more than any other pitchers in baseball, these guys should give you lots of productive innings per start.
