Managers can protest a game when they allege that the umpires have misapplied the rules. The umpires must be notified of the protest at the time the play in question occurs and before the next pitch or attempted play begins. If the play in question ended the game, a protest can be filed with the league office until noon the following day. No protests are permitted on judgment calls by the umpires.
Major League Baseball's executive vice president of baseball operations later determines whether the protested decision violated the rules, though the game will not be replayed unless it is also determined that the violation adversely affected the protesting team's chances of winning.
