What is the Definition of a Losing Pitcher in Baseball?
The losing pitcher is the opposite of a winning pitcher. They are the pitcher that is responsible for the run that allows the opposition to take the lead. This can occur at any point in the game, and the losing pitcher isn’t always the last pitcher to pitch. Providing the defense does not overtake the offense after allowing them to enter the lead, the pitcher who allows that run will be considered the losing pitcher. A losing pitcher is credited with a loss.
