Do Umpires Give Preferential Treatment To Some Players?
SABR presentation by Patrick Kilgo, Hillary Superak, Lisa Elon, Mark Katz, Paul Weiss, Jeff Switchenko, Brian Schmotzer and Lance Waller.
Here are their conclusions. I’ll post their file on my site tonight. You can also read from Phil.
Umpires absolutely favor veterans with respect to false strikes
Umpires most likely favor veteran pitchers with respect to false balls. No evidence of benefit to veteran hitters
“Good” pitchers see the most preferential benefit
No evidence of rookie hazing
