In baseball and softball, a double play (denoted as DP in baseball statistics) is the act of making two outs during the same continuous play. Double plays can occur any time there is at least one baserunner and fewer than two outs.
In Major League Baseball (MLB), the double play is defined in the Official Rules in the Definitions of Terms, and for the official scorer in Rule 9.11.[1] During the 2023 Major League Baseball season, teams completed an average 132 double plays per 162 games played during the regular season.[2]
