Welcome to Baseball’s Umpire Area
The World Baseball Softball Confederations aims to identify, train and assess umpires across the globe in order to improve the quality and consistency of officiating throughout the game of baseball. The WBSC strives to promote better communications between umpires, coaches and staff to be able to provide consistency in the interpretation of the Official Baseball Rules.
The WBSC is concerned about unnecessary and violent collisions primarily with the catcher at home plate, and with infielders at all bases. The intent of this rule is to encourage base runners and defensive players to avoid such collisions whenever possible.read more
