Making three outs during the same play in baseball
In baseball, a triple play (denoted as TP in baseball statistics) is the act of making three outs during the same play. There have only been 737 triple plays in Major League Baseball (MLB) since 1876,[1] an average of just over five per season.
They depend on a combination of two factors, which are themselves uncommon:
- First, there must be at least two baserunners, and no outs. From analysis of all MLB games from 2011 to 2013, only 1.51% of at bats occur in such a scenario.[2] By comparison, 27.06% of at bats occur with at least one baserunner and fewer than two outs,[2] the scenario where a double play is possible.
- Second, activity must occur during the play that enables the defense to make three outs. Common plays, such as the batter striking out or hitting a fly ball, do not normally provide an opportunity for a triple play. A ball hit sharply and directly to an infielder, who then takes very quick or unanticipated action, as well as confusion or mistakes by the baserunners, is usually needed.
In baseball scorekeeping, the abbreviation GITP can be used if the batter grounded into a triple play.[3]
