How One Club Integrates Analytics into Player Development

This is Mike Hattery’s second piece as part of his September residency at FanGraphs. Hattery writes for the Cleveland-based site Waiting for Next Year. He can also be found on Twitter. Read the work of all our residents here.

Certain players in baseball become symbols, willingly or not, for the seismic conceptual shifts of which they’re a part. Jeremy Brown and Scott Hatteberg, for example, remain emblematic of Oakland’s attempts earlier this century — the sort of attempts documented in Michael Lewis’s Moneyball — to exploit inefficiencies in the game. Ben Zobrist, meanwhile, continues to represent the ability of Tampa Bay’s front office to identify valuable, if overlooked, talent. More recently, Daniel Murphy and Josh Donaldson have become the public face of the air-ball revolution. 

For some who follow the minor leagues, catcher Eric Haase in the Cleveland system has achieved a similar level of notoriety. Despite lacking the name recognition of either Murphy or Donaldson, Haase has nevertheless transformed himself in much the same way as those two, elevating the ball more often and reaping the benefits.

Eric Haase’s Power Spike
Year Level PA FB% IFFB% ISO
2016 AA 246 43.3% 27.7% .230
2017 AA 381 52.2% 14.7% .315

Haase’s 2017 season has shifted expectations about his career. Merely a fringe prospect entering the season, he’s now regarded, at the very least, as a future major-league backup who’ll punish opposing pitchers with power from time to time. As FanGraphs’ own Eric Longenhagen noted in an edition of his Daily Prospect Notes last month:

Some scouts question his mobility and he has fringe arm strength, but Haase receives pretty well and has plus, all-fields raw power. While strikeout prone and unlikely to develop even an average hit tool, Haase’s combination of power and position make him a solid bet to play some sort of big-league role, likely as a slugging backup, though some scouts like him as a sleeper regular.

Haase’s collection of statistical indicators earned him the 47th spot on Chris Mitchell’s midseason top-100 KATOH rankings.

Sunday Notes: Zack Littell Knows a 20-1 Record is Relative

Two summers ago, I asked Greg Mroz — then a radio broadcaster for the Clinton Lumber Kings — which of their players I should interview and write about. He recommended Zack Littell. I proceeded to do so for a Sunday Notes column, despite never having heard of him. Not too many people had. At the time, Seattle’s selection in the 11th round of the 2013 draft barely registered a blip on prospect radar.

Mroz deserves some props, because Littell is now living large. Playing for two different organizations, at two different levels and for three different teams, Littell finished this season with a record of 20-1. The most recent of his victories came on Wednesday with Minnesota’s Double-A affiliate, the Chattanooga Lookouts, in the Southern League playoffs.

No one saw it coming — you can’t predict 20-1 — and the same could probably be said of his multiple changes of address. Seattle swapped Littell for James Pazos last November, and the Yankees subsequently traded him to the Twins as part of July’s Jaime Garcia deal.

“The first one was out of nowhere,” Littell told me. “I was at home, hanging out in the offseason, and got a call — one minute I was a Mariner, and the next minute I was a Yankee. Coming to the Twins… I got scratched from a start the night before, so I kind of knew something was up, but I thought I was going to the A’s because of all the Sonny-Gray-to-the-Yankees rumors. But when I got the call from (New York GM Brian) Cashman, he told me I was going to the Twins.”

The 21-year-old North Carolina native is smart enough to know that W-L records are to be taken with a grain of salt. Read the rest of this entry »

A Solution for September Roster Insanity

So, things might be getting out of hand…

A lot of folks inside and outside the game don’t care for September roster expansion. After all, why play the game one way for five months, with one set of roster rules, and then in the most crucial month of the season change the limits of rosters?

The Disconnect in Pittsburgh

Full disclosure: as you might be aware, I authored a book on the Pirates — Big Data Baseball — which was published in 2015. As a result, it’s possible that I write this piece with some bias.

Still, I wouldn’t have entered into that book project if I thought the Pittsburgh Pirates were run by fools, engaged in uninteresting practices, and set for a catastrophic 2014 season. To work on the project, I had to believe the Pirates were a team likely to enjoy more success.

I pitched the book following the 2013 campaign, after the Pirates’ first winning season since 1992. I felt it was a compelling narrative: the Pirates ended the longest consecutive streak of losing seasons in North American pro sports history by residing on the cutting edge of analytics and innovating new practices (like having a quant embedded in the clubhouse) while also remaining attentive to the human element. It was a story of creativity, collaboration, and peak Andrew McCutchen.

Time to Learn Who Chad Green Is

The Yankees bullpen is short on neither talent nor name value. Most baseball fans are aware of Aroldis Chapman, even if they’re not aware that he’s been in a funk. Likewise, many baseball fans are aware of Dellin Betances, and they’ve generally heard of David Robertson, who this year has re-emerged as terrific. To make the unit all the more deep, the Yankees acquired Tommy Kahnle, one of the year’s big bullpen breakout stories. Kahnle has struck out 38% of his opponents, ranking him seventh in baseball among regular or semi-regular relievers.

Kahnle, in the breakout sense, is a surprise. He finally has the results to go with the powerful stuff. And yet Kahnle may play second fiddle in here, because of another development. The highest strikeout rate for any reliever belongs to Craig Kimbrel. Well, sure. In second place, we find Kenley Jansen. Yes, of course. The name in third place reads “Chad Green.” And he’s up around 60 innings, so this isn’t just a hot week or month. Green has piled up the strikeouts, and as a consequence, he ranks seventh among all relievers in WAR. Chad Green made his season debut on May 9.

Is the LeMahieu Shift the Boldest One Ever?

In the age of the shift, it takes a lot for a particular defensive alignment to merit real attention.

But over the weekend, the Diamondbacks managed to do just that, utilizing what appears to be the most dramatic shift in recent history — notable even more so because the park at which they did it, Coors Field, features one of the game’s largest outfields.

We’ve seen about every variety of infield shift over the last four years, but we’ve never witnessed anything quite like what the Diamondbacks employed against DJ LeMahieu.

That gets your attention. That is bold.

Sunday Notes: Vision and Data Fuel Opportunity for Tommy Pham

A few weeks ago, colleague Jeff Sullivan wrote that Tommy Pham is the best player on the Cardinals. It’s hard to argue. With a month to go in what has been a breakout season, the 29-year-old outfielder is slashing .311/.407/.522, and he has 19 home runs in 431 plate appearances. He attributes his success to two things.

“Vision,” said Pham. “I got my contacts squared away this year, and that’s helped me improve tremendously. I’d say we could start there. The other thing is that I’ve put myself in a position to where I’m playing every day. In previous years I played for stretches, but then I’d sit on the bench. Last year I had an .870 OPS in the middle of August, then I basically became a designated pinch hitter. In 2015, I had an .824 OPS in my rookie season. I’ve always produced. It’s just that I’m playing every day now, so you get to see more.”

His production has never been better, and seeing the ball better is clearly helping.

“Just look at the numbers, man — I was striking out 38% last year,” stated Pham, who elaborated that depth perception was the issue. “Now I’m striking out 15% less. That means I’m putting more balls in play, which means I’m going to have better results.”

He’s well-versed in more than just probability. The Las Vegas native is a big believer in using any and all data to his advantage. Pham — an affirmed FanGraphs reader — studies his stat page to see which aspects of his game need improvement. If data shows that he’s a negative in a specific area, he strives to turn it into a positive. Read the rest of this entry »

The Astros Make Their Big Splash

A month ago, when the dust settled on the July 31st trade deadline, the Astros had added just left-hander Francisco Liriano, whose struggles were one of the main reasons the Blue Jays failed to contend in 2017. It was an underwhelming upgrade for a team headed for the postseason, and the fact that the team thought they had a deal for Zach Britton was little solace to disappointed fans and players who hoped for more reinforcements.

Well, it took a month, but reinforcements are here, and this particular reinforcement throws really hard.
