They make decisions on whether a pitch is a ball or a strike, and they also make calls on plays such as whether a runner is safe or out. Umpires also have the authority to eject players or coaches from the game if necessary. Umpires are an important part of the game, and their decisions can have a major impact on the outcome of the game.
