how do you qualify for a save in major league baseball
In baseball, a save (abbreviated SV or S) is credited to a pitcher who finishes a game for the winning team under certain prescribed circumstances, described below. The number of saves, or percentage of save opportunities successfully converted, is an oft-cited statistic of relief pitchers, particularly those in the closer role. It became an official Major League Baseball (MLB) statistic in 1969. Mariano Rivera is MLB's all-time leader in regular season saves with 652.
