Updated Hitter Shift Data: Effect on xBABIP

It’s official. 100% of my value is bothering @jeffwzimmerman to run data and then use that data for said content. I did just that this morning for updated shift data. I believe the last time he posted related content on RotoGraphs was here back in May looking at: Early Hitter Shift Data.

It was because of this post and his balls in play (groundball and pop-up rates) that led me to believe Albert Pujols was going to drop off/continue his downward trend. I guess I pushed out the fact that he was the best hitter of his generation. While the .375 BABIP (from the above link) against shifts did not last, he’s at a very respectable .284. Between this and additional discipline (best contact rate since 2008 and hacking less at stuff outside of the zone), he is able to hover around a .280 BA, which remains elite in conjunction with 30HR, 90R and 100+RBI.

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.

Verifying xBABIP potential

On 9/3, I posted Adjusting Fantasy Value with expected (x)BABIP and xHR. These were used to adjust batting average, OBP, SLG and OPS for your different leagues’ formats.

Based on xBABIP, Michael Brantley and Anthony Rendon jumped in value sandwiching in Mike Trout as the top 3 adjusted Fantasy Values for standard 5×5 formats (HR, SB, R, RBI and AVG).

Here, I’ll attempt to verify the BABIP potential for standard 5×5 leagues. I am therefore using column 2 (sum of the 5×5 descriptive/actual z-scores: HR, SB, R, RBI and AVG) and comparing it to column 3 (sum of the 5×5 expected z-scores: xHR, SB, R, RBI and xAVG). SB, R and RBI are not adjusted even though they should be so consider this a way to play down the overall effect.

Adjusting Fantasy Value with xBABIP and xHR: AVG/OBP/OPS League Rankings

I’m going to use all things @jeffwzimmerman for this post.

First is xBABIP. During this past offseason, Jeff found an xBABIP equation which correlated better than just BABIP year to year with the use of new Inside Edge data and player speed scores. I believe his last full updated list was posted on July 25th of this season, but he and the team provided me with an updated list this morning in order to use the data to interpret expected(x)FantasyValue vs. actual/descriptive(a)FantasyValue.

Early 2015 Projections: Adjustment for Position

Earlier this week, Jeff Zimmerman presented Early 2015 Hitter Projections using Steamer and/or ZIPS averaged ROS projections. The main contingency at this time: all values are set to 600 plate appearances. If I had all the time in the world, I would go through the list and manually adjust the PA based on lineup position, career PA/G, etc, but I’m not that much of a Mensch.

The next day, Mike Podhorzer highlighted some of the surprises ranked in the top 30. Again the 600 PA contingency is clear as Rajai Davis, Jarrod Dyson and Corey Dickerson make the list although if Dickerson doesn’t get platooned, I (and Mike) think he’ll surpass expectations. His splits page tells us there is no good reason to platoon him.

In Mike’s intro, he also referenced that there is no adjustment for position in Jeff’s SGP rankings. That’s where this post comes in.

Bullpen Report: August 30, 2014

Dodgers at Padres: Joaquin Benoit’s shoulder pain his back and Kevin Quackenbush should be owned in all leagues and perhaps for the rest of the season:

It’s not yet known when Benoit will be available again. At this point, maybe assume 11 days like the last timeframe since it’s similar pain.

Yankees at Blue Jays: Future starter/ace, current september bullpen asset, Aaron Sanchez looked great striking out 3 in 2 scoreless innings for his first major league save. He threw 19 of his 28 pitches for strikes. And on 12 swings, the Yankees were only able to put the ball in play 3 times. His minimum fastball velocity was 96 MPH. The one breaking ball he threw was a beaut. to Derek Jeter on a 2-2 count. Probably anyone other than Jeter would have chased (just missed low). He’s only given up 1 ER in his last 8 appearances with a 12K:1BB ratio. IMO he’s got a great Sinker-Fourseam-Curveball repertoire in conjunction with the velocity to succeed longterm. He’s only thrown 3 Changeups thus far, but I’d assume that remains part of his starting repertorie. If so, more whiffs should come; the groundball induction is already apparent; and his command (4.3% BB-rate) thus far is a huge bonus.

Bullpen Report: August 29, 2014

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).

Bullpen Report: August 23, 2014

  • 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.

Pitcher Over/Under Performers

I wanted to highlight Pitcher over and under performers. Naturally, Mike Podhorzer has already done that and more concisely and eloquently than I ever could. In conjunction to what he did (ERA vs. SIERA within this year), I wanted to look at pitchers’ skills and luck relative to last year.

By “skills” I mean K%-BB%, combined Contact% and SwStr%, GB/FB and IFFB%. These columns are in green.

By “luck” I mean BABIP, LOB% and HR/FB. These are in some emotional shade of red.

I took all the 2014 vs. 2013 differentials and z-scored them. I summed them up and presented them under column 3 (“SKILL”) and column 4 (“LUCK”). In short, these are not their skill and luck scores for 2014, but their change relative to 2013…in relation to how much everyone else from this list changed (50 IP qualifier).

Bullpen Report: August 20, 2014

  • The dreaded “closer in a non-save situation” …and Casey Janssen strikes out 2! The Blue Jays are only 4.5 games back from the Wild Card and Ryan Braun and Aramis Ramirez was up to start the inning so manager John Gibbons appropriately went all out. Janssen struck them both out, even though he only induced one whiff in seven swings total for the inning. Still, 12 of of his 15 pitches were thrown for strikes/fouls.
  • “Put it in the (anxiety-inducing) Books” says (thinks) Howie Rose. With Jenrry Mejia unavailable due to his back and not his hernia supposedly, Jeurys Familia relieved Vic Black in the 8th after he loaded the bases. While he walked Sam Fuld forcing in run, he struck out Andy Parrino and got Josh Donaldson to ground out to shortstop. He got away with two things in the innings: the third strike to Parrino was a bit outside and the breaking ball on a full-count to Donaldson was a bit of a hanger although IMO it needed to be a breaking ball. At least it was thrown for a strike. A Stephen Vogt double after a Derek Norris strikeout in the 9th was the only other damage to give Familia the 5-out save. In any case, I think if he can continue to locate the fastball running outside on a lefty, he could be effective to all handedness. I’m a fan of the 3-pitch Fastball-Slider-Sinker repertoire that induces enough swinging strikes (12.4%) and ground balls (56%). We’re seeing it already in the outcomes and on the pitch level: According to Baseball Pro’s Pitchf/x Leaderboard, Familia has the 12th fasted RP velocity on the Fastball; 7th best whiff rate (51.43%) and 9th best GB/FB rate (3.2) on the slider; and 6th best whiff rate on the sinker (22.37%) which balances the fact that it only induces a 3.33 GB/FB ratio on it. If he can control the BB-rate, he should be successful and consume closing duties for at least the remainder of this year based on Mejia’s ailments. P.S. I’m a Mets fan so I apologies for the longevity associated with this run-on.
  • Mark Melancon picks up the win (+1K) with a perfect inning in the top of the 9th vs. the Braves due to a Justin Upton error on a routine fly ball that allowed Jordy Mercer to score on a sac fly in the bottom of the 9th.
  • Neftali Feliz hasn’t let up a run since August 3rd (only 6 appearances since). On this day, he had a 100% HR/FB ratio as Marcell Ozuna and Jarrod Saltalamachhia both went deep.
  • A Bullpen Report where I don’t get to talk about Ken Giles or Brad Boxberger is a report I don’t enjoy writing nearly as much. Luckily, Ken Giles struck out Chris Denorfia, Logan Morrison and Dustin Ackley – all swinging in the 8th. To date, for relievers (200 pitches minimum), Giles has the 6th fastest FB velocity (97.72 MPH) with a top 15 whiff rate (26.7%). He also has a top 15 whiff rate on the slider (50.6%).
  • The 8-9 punch of Darren O’Day and Zach Britton continues to ensure wins for the AL East leading O’s. O’Day strikes out both batters he faces and Britton strikes out 1 in a perfect 9th. O’Day threw 8/10 pitches for strikes: 4 whiffs, 3 looking, and only 1 time did the bat make (foul) contact with an O’Day offering. But Zach Britton! Whose ballsiest forecast had him at a 2.00 ERA and 30 saves?! a 77+% (77!!!) ground ball rate (11% flies and 12% liners) backs up the elite .222 BABIP right now. Nothing else on him screams elite, but the balls in play breakdown verifies the 2.04 ERA through a sub-2.00 SIERA.
