In the sport of baseball, a doubleheader is a set of two games played between the same two teams on the same day. Historically, doubleheaders have been played in immediate succession, in front of the same crowd. Contemporarily, the term is also used to refer to two games played between two teams in a single day in front of different crowds and not in immediate succession.

Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called "runs". The objective of the defensive team is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate.
