Study: Pitchers more likely to ‘bean’ batters in hot weather

USA Today:

Researchers analyzed data from more than 57,000 Major League baseball games from 1952 through 2009 and found that pitchers whose teammates were hit by a pitch were more likely to nail an opposing batter when the temperature reached 90 degrees F than on cooler days.
