From BR Bullpen. A double switch is a substitution during which two or more players are substituted simultaneously and take places in the batting order different from those of the player they replaced. A double switch is typically used in situations where the designated hitter is not used and the pitcher is one of the players being substituted. The purpose of the move is to change the pitcher's slot in the batting order, so that the new pitcher does not immediately come up to bat in the next half inning.
