Previewing the Yankees September call ups

Monday marks the start of September, which means Major League teams are allowed to carry up to 40 players on their active roster for the remainder of the season. Very few September call ups are game-changers, but having a few extra players around gives teams some added roster flexibility — something that’s often at a premium now that bullpens run seven, eight, or even nine men deep. Most September call ups don’t happen on the first of the month, as many players stay with their minor league squads through the end of their seasons. This shouldn’t be a factor for the Yankees though, as none of their high-level affiliates have qualified for this year’s minor league playoffs. Both the Trenton Thunder and the Scranton Railriders finish up their seasons on Monday (September 1st), so most — if not all — of the team’s call ups will probably happen right away. So without further adieu, here’s a look at some guys the Yankees might wind up filling out the Yankees roster this September. Continue reading

Why haven’t the A’s had any good pitch framers?

The ability to quantify the value of catcher framing has been one of the biggest sabermetric breakthroughs of the last decade. By parsing through PITCHf/x data, analysts like Mike Fast, Max Marchi, Dan Brooks, and Harry Pavlidis have managed to shed light on which catchers are adept at turning balls into strikes, uncovering hidden value in otherwise unremarkable players, including Rene Rivera, Chris Stewart, and of course, Jose Molina.

MLB front offices have taken notice. Several teams, including the Yankees, Rays, Red Sox, Pirates, Padres, and Brewers have begun hoarding good-framing catchers over the past few years. But one team that’s missing from this list are the Oakland Athletics, who have historically been among the first adapters of sabermetric principles. One would think that the A’s would be all over the Jose Molina’s and Chris Stewart’s of the world, yet Billy Beane and co. seem to have missed the memo on acquiring good framers. In fact, they’ve made a habit of employing poor ones. According to Baseball Prospectus‘ model, A’s catchers rank fourth from last in framing runs saved this season. This isn’t a one year anomaly, either. Here’s a look at all of the catchers the A’s have used since 2010, along with their career framing numbers.

Does Francisco Cervelli have a future with the Yankees?

Francisco Cervelli‘s been with the Yankees for quite some time now. Originally signed out of Venezuela way back in 2003, Cervelli broke in with the Yanks in 2008, making him one of just five current Yankees to have played for the team in the old stadium. Along the way, Cervelli’s caught hundreds of Yankee pitchers — from Carl Pavano to Masahiro Tanaka, served a 50-game PED suspension, and even celebrated a World Series victory with A-Rod and Jay-Z.

Cervelli’s never been the main guy behind the plate, but has been a big part of the Yankees’ catching situation for six years now. And although he was a glove-first player for most of his career, he’s shown signs of life with the bat the past couple of years, hitting .275/.352/.456 — way more than adequate for a catcher. Couple that with his much-improved defense, and Cervelli’s developed into a pretty decent player. But beyond this year, the 28-year-old’s future with the Yankees looks a little uncertain.

Searching for the existence of team clutch as a repeatable skill

As you’ve probably heard by now, the Baltimore Orioles have made a habit of outperforming their run differential these last three years. In 2012, they finished the year 93-69, but their +7 run differential suggested they didn’t play much better than a .500 team. This year, they’re at it again. They currently sit atop the American League East with a 73-52 record, but their peripheral stats suggest they’ve lucked into a few wins along the way.

This has inevitably lead to some disagreement over the true talent of recent Orioles teams. On the one hand, it’s been well established that things like base runs and Pythagorean records do a pretty good job of predicting a team’s win-loss record. But at the same time, Buck Showalter’s Orioles have been pulling this off for a while now. Even if you understand and accept the concept of random variation, its a little hard to believe that the Orioles’ run has been entirely due to luck.

Jeff Sullivan recently penned a convincing article, dispelling the myth that clutch teams remain clutch over an extended period of time. He compared teams’ first half clutch scores to their second half scores, finding no correlation between the two, concluding that “team clutch” is not a repeatable skill. Continue reading

Jacob Lindgren’s a future star reliever… and the future may be now

Jacob Lindgren, this year’s second round draft pick, has been about as unhittable as it gets in his first two months as a professional. After agreeing to a contract on June 14th, the 21-year-old lefty reliever has breezed through four levels of the minors, posting a 0.96 ERA and striking out 51% of opposing hitters along the way. In addition to his on-field performance, all scouts agree that his stuff – especially his slider — is absolutely filthy. All things considered, Lindgren would almost certainly be better than both of the team’s current lefties, David Huff and Rich Hill, meaning there’s a very good chance he’ll be summoned to the majors in the next couple of weeks.

Lindgren’s minor league numbers have been great, but pitching in the big leagues is an entirely different animal. The hitters are more discerning at the plate and are much more likely to capitalize on mistake pitches. As a result, dominant minor league numbers don’t always carry over to the big leagues. Take Dan Runzler, for example, who was my top comp for Lindgren when he was drafted based on PITCHf/x and scouting reports. Runzler put up a filthy 0.76 ERA and 36% K% in the minors in 2009, but went on to throw just 72 innings in the majors before being exiled to Japan last month. Continue reading

Is there any hope for Carlos Beltran’s bat?

Substandard would be an appropriate description of Carlos Beltran‘s 2014 campaign. He was added to be the lineup’s bopper after Robinson Cano‘s departure, but Beltran’s failed to live up to his reputation, batting .235/.292/.420 (94 wRC+) in 370 plate appearances. Age and health are the most obvious factors to assign blame, but is there anything behind the numbers that hint at improvement? Continue reading

Robinson Cano and the difficulty of replacing a star player

A few days ago, I saw this tweet:

Jacoby Ellsbury, Brian McCann, Carlos Beltran: 4.1 WAR, $53M Robinson Cano: 5.1 WAR, $24M Not second guessing, just saying.

— Dan M. (@LeftFieldDan) August 14, 2014

When Cano left for the Mariners, the Yankees had the daunting task of replacing a five-to-seven win player in 2014. Frankly, this was an impossible task given the fact that Cano is the best second baseman in baseball. Instead, the Yankees reallocated money to other positions of need to make up for Cano’s vacancy.

According to Dan Szymborski’s preseason ZiPS, Cano was projected to amass 5 WAR, while the new trio of new Yankees forecasted for 9 WAR (Ellsbury 4, McCann 3, Beltran 2). In total, it looked like the Yankees would come out ahead immediately while limiting long-term risk. Instead, Ellsbury has been the lone guy carrying his weight. Both Beltran and McCann have underperformed, while the former has also dealt with some health issues. Continue reading

Don’t worry (too much) about the Yankees bullpen

The Yankees bullpen has really scuffled of late. For the second time in two games, the bullpen cost them the game last night, when Dellin Betances and Shawn Kelley yielded four runs in the bottom of the eighth, turning a 3-1 lead into a 5-3 deficit. Monday night, it was Adam Warren who coughed up three runs in what was a one-run game. Even closer David hasn’t seemed himself lately, and has now walked five batters in his last five outings. Up until recently, the Yankees bullpen had been arguably the team’s biggest strength, but in recent weeks, the wheels have begun to fall off the wagon. Rough outings are to be expected – and have been received — from the guys like Chase Whitley, Matt Daley, David Huff, and Rich Hill, who sit at the bottom of the bullpen totem pole. But the top dogs have also started to struggle. Over the last 20 days, Robertson, Betances, Warren, and Kelley have all averaged a FIP below 4.00. That’s pretty bad, especially for a reliever: The American League average for reliever FIP is 3.63.

Bullpen

As good as the Yankees ‘pen has been this year, its not like its been completely smooth sailing. Betances got off to somewhat of a shaky start, Warren and Robertson both went through rough patches in May and June, and Kelley’s been all over the place. But this is the first time all season that all four have struggled at the same time. This turn of events is particularly troubling as the Yankees have reached a point in their season where there’s little margin for error. In order to make the playoffs, they’ll need just about everything to go their way from here on out, including the performance of their key bullpen pieces, especially following Matt Thornton‘s departure, which has left them without a usable lefty reliever on the roster.

There’s no denying that the Yankees bullpen has performed poorly over the past few weeks, but its more likely to be a fluke than anything else. A reliever only throws around 10-15 innings a month, which isn’t nearly enough to make any definitive conclusions about a player’s abilities. On top of that, there’s no reason to believe these pitchers’ struggles are in any way related. Its not like Adam Warren‘s ineffectiveness somehow caused Robertson to start struggling as well.

Sure, there’s a chance that any one of these pitchers’ slumps will turn out to be more than a blip on the radar. Its not hard to imagine Betances or Warren hitting a wall given the exorbitant amount of innings they’ve thrown this season. But until we start to see something tangible — like a drop in velocity – its probably not worth getting worked up about. Robertson, Betances, Warren, and Kelley have all established themselves as viable bullpen options over the season’s first four months, and I expect nothing less from them over the final six weeks.

What types of hitters have large platoon splits?

Big league teams today employ a myriad of data-driven strategies to eek every last drop of value from the players on their rosters. Many of these strategies consist of matching up hitters and pitchers based on their handedness. Between lineup platoons and highly-specialized bullpens, managers today go to great lengths to ensure they’re putting their players in the best possible situation to succeed.

It’s easy to see why. With very few exceptions, Major League hitters hit much better against opposite-handed pitching. In terms of wOBA (vs. opposite-handed – vs. same-handed), lefties perform about .031 better against righties, while righties hit .043 better against lefties. Yet not all platoon splits are created equal. Players like Shin-Soo Choo, David Wright, and Jonny Gomes are notorious for their drastic splits, while others put up comparable numbers no matter who’s on the mound. Ichiro Suzuki and Alex Rodriguez are a couple of the no-platoon-split poster boys.

Ok, so some batters have bigger platoon splits than others, but is there any particular reason for this? Take Choo for example. Is there something inherent to his skill set or approach that causes him to struggle against  lefties?

Hoping to find an answer, I ran some regressions in search of attributes that might make a player more likely to have an exaggerated platoon split. I tested all sorts of things out there — from walk rate and swing% to a player’s height and throwing arm — but didn’t come away with much. Aside from a hitter’s handedness, attributes that proved statistically significant included: a hitter’s overall wOBA, his line drive rate, his strikeout rate, and his contact rate on pitches out of the zone, but even those relationships are extremely weak. It takes .100 points on a batter’s wOBA, or a 10% increase in K% or LD%, to move a batter’s platoon split  by just .010 points. This tells us something, but not a ton, and at the end of the day, these variables account for a nearly negligible 4% of the variation in hitters’ platoon splits. Here’s the resulting R output. My sample included all batter seasons from 2007-2013 with at least 100 plate appearances against both lefties and righties, excluding switch hitters:

Platoons


Good hitters or guys who strikeout frequently might be a little more prone to having large platoon splits. But for all practical purposes, a player’s ability to hit one type of pitching better than the other seems to be a skill that’s independent of all others. Aside from going by a player’s platoon stats, which can take years to become reliable, there’s little we can do to anticipate which hitters might fare particularly bad against same-handed pitching. And with the exception of players with long track records of unusual platoon splits — like Choo and Ichiro — it’s generally safe to assume that any given hitter’s true-talent platoon split is within shouting distance of the average: .043 for lefties and .031 for righties.

What might the Yankees have in Bryan Mitchell?

Brian Mitchell didn’t see any game action in his previous two stints with the Yankees, but the 23-year-old finally made his big league debut yesterday, throwing a scoreless eighth and ninth. Mitchell’s command seemed a little shaky, but his stuff was unquestionably good, enabling him to strikeout both Jason Kipnis and Michael Brantley. He primarily threw two pitches — a mid-90′s fastball and an impressive curve — which accounted for 28 of 29 (97%) of the pitches he threw. He also mixed in a token slider.

When Jose Ramirez, Chase Whitley, and Shane Greene debuted with the Yankees this year, I queried the PITCHf/x database in search of pitchers with a comparable arsenal if pitches and similar stuff. Today, I’m repeating this exercise for Mitchell. To find comps for Mitchell, I looked for players (1,000 pitch minimum) since 2008 who threw either a fastball or a curve at least 80% of the time. I turned to PITCHF/x to find out how often these pitcher’s pitches fell within the minimum and maximum values for Mitchell’s velocity, break angle, break length, and spin from yesterday’s game. These are the pitchers who threw the highest ratio of pitches comparable to what Mitchell threw. Continue reading
