Abstract: This paper identifies discrimination in the professional baseball league in the United States. We consider players, umpires, and team managers as employees, middle managers, and employers in general workplaces. Using huge pitch-bypitch tracking data of the Major League Baseball reveals that umpires from North America favor players with the same region when a pitcher from North America and a batter from other regions are facing. The impact of this is dramatic: players from other regions lose their chances to hit by the unfair pitch call, which values to loss of about $130,000 for in three years.
