Study: “Major League Baseball umpires express their racial/ethnic preferences when they evaluate pitchers”

40 Comments

I recall everyone discussing a study in which it was posited that umpires tend to favor pitchers of the same race a few years ago. Perhaps it was an earlier version of the study whose publication was announced earlier this afternoon, perhaps it was a different study.  I’m not sure.

But either way, there is a newly-published study to that effect out in the latest issue of the American Economic Review. Here it is in full. Here’s the abstract of the study, as set forth at the Freakonomics blog:

Major League Baseball umpires express their racial/ethnic preferences when they evaluate pitchers. Strikes are called less often if the umpire and pitcher do not match race/ethnicity, but mainly where there is little scrutiny of umpires. Pitchers understand the incentives and throw pitches that allow umpires less subjective judgment (e.g., fastballs over home plate) when they anticipate bias. These direct and indirect effects bias performance measures of minorities downward. The results suggest how discrimination alters discriminated groups’ behavior generally. They imply that biases in measured productivity must be accounted for in generating measures of wage discrimination.

I haven’t read the full study yet. All I know is that, when it last made the news, it caused a stink.*  I presume it will cause a new stink now.  And the stink will likely have very little connection whatsoever with the underlying data because, let’s face it, we as a nation are unable to talk about race without making ourselves look silly and self-conscious and obnoxious and guilty and sometimes all of those things in between.

But let’s not have that stop us now! Go ahead, folks, react!

 

*I’m positive I blogged about the study the first time I heard about it too, but I can’t for the life of me find it, either in the HBT archives or in the old Shysterball archives.  If anyone else can find it, please let me know, because I’m curious to see what I thought of it at the time. Not that it would stop me from having a different response now. I’m nothing if not inconsistent when the facts on the ground or my personal experience and/or disposition changes about a matter.  I can just be annoying that way! 

Astros push ALCS to Game 7 with 7-1 stunner against Yankees

There’s just something about playing in your home ballpark. The Astros decimated the Yankees at Minute Maid Park on Friday, riding seven scoreless innings from Justin Verlander and a pair of big runs from Jose Altuve to win 7-1 and force a Game 7 in the American League Championship Series.

Through the first four innings, however, the teams looked equally matched. Luis Severino no-hit the Astros through 3 2/3 innings, losing his bid on Carlos Correa‘s line drive single in the fourth. The Astros returned in the fifth to do some real damage, drawing two walks and plating the first run of the night with Brian McCann‘s ground-rule double off of the right field wall. Things didn’t get any easier for Severino. Jose Altuve lined a two-RBI base hit into left field, upping Houston’s advantage to three runs.

Verlander, meanwhile, muted the Yankees’ offense with seven innings of five-hit, eight-strikeout ball. While he didn’t come close to matching his complete game effort in Game 2, he was still plenty dominant against a struggling New York lineup. No player reached past first base until the sixth inning, when a pair of base hits from Chase Headley and Didi Gregorius gave the Yankees their first runner in scoring position. That didn’t last long, though, as Gary Sanchez grounded out on a 3-0 slider to end the inning.

In the seventh, Houston’s ace got into another spot of trouble. He walked Greg Bird on six pitches to start the inning, then plunked Starlin Castro on the wrist. Aaron Hicks struck out, in part thanks to a questionable call by home plate umpire Jim Reynolds, but it was Todd Frazier who presented the biggest threat after returning an 0-1 fastball for a 403-foot fly out to left field. Luckily for Verlander, George Springer was there to bail him out with a leaping catch at the wall.

The Yankees kept things exciting in the eighth, too. Aaron Judge ripped his third postseason home run off of Brad Peacock, taking a 425-footer out to the train in left field to spoil the Astros’ shutout. That was the only real break the Yankees got, however, as Altuve, Alex Bregman and Evan Gattis returned in the bottom of the inning to tack on another four runs, including Altuve’s solo shot off of David Robertson:

Ken Giles handled the ninth, expending 23 pitches and giving up a base hit and a walk before retiring Frazier and Headley to end the game. Thanks to Houston’s winning efforts, the two teams will compete in their first seven-game Championship Series since 2004 — and this time, at least one of them is guaranteed to come away with a win.

Game 7 of the ALCS is set for Saturday at 8:00 PM ET. Houston right-hander Charlie Morton (14-7, 3.62 ERA) is scheduled to face southpaw CC Sabathia (14-5, 3.69 ERA).
