U-M study challenges notion that umpires call more strikes for pitchers of same race
Date:5/22/2013

ANN ARBORA University of Michigan study challenges previous research that suggests umpire discrimination exists in Major League Baseball.

The study, a collaboration between researchers at U-M and the universities of Illinois and Florida, looks deeper into the controversial argument over whether MLB umpires discriminate by calling more strikes for pitchers of the same race. It found little statistical evidence to support that claim, said Jason Winfree, associate professor of sport management at the U-M School of Kinesiology.

Winfree and co-authors Scott Tainsky of Illinois and Brian Mills of Florida, analyzed millions of pitches between 1997 and 2008 and ran the data through various statistical models. Their results suggest that findings of discrimination were questionable.

A draft of the earlier study that initially found evidence of discrimination was released in 2007 and published by the American Economic Review in 2011. National media reported on both the draft of the study and on its later publication.

In the U-M study, Winfree and his co-authors analyzed both their own data as well as that of the previously published study, but did not get consistent results when using different statistical methods and variables.

"Based on what we found, it's(discrimination) certainly not conclusive, and we could make an argument that there's actually reverse discrimination if you look only at averages," Winfree said. "Our point is (that) with something like this you want to look at the data a lot of different ways and see if you get a consistent result each time with each method. It's a pretty bold claim to say there is racial discrimination."

Winfree and colleagues found that the only specifications that suggested discrimination were when the analysis treated pitchers as completely separate players when pitching in stadiums where umpires were monitored. This seemed to drive much of the findings in the ear
