A platoon system in baseball or American football is a method for substituting players in groups (platoons), to keep complementary players together during playing time. Baseball In baseball, a platoon is a method of sharing playing time, where two players are selected to play a single defensive position. Usually, one platoon player is right-handed and the other is left-handed. Typically the right-handed half of the platoon is played on days when the opposing starting pitcher is left-handed and the left-handed player is played otherwise. The theory behind this is that generally players hit better against their opposite-handed counterparts, and that in some cases the difference is extreme enough to warrant complementing the player with one of opposite handedness. Strategy Right-handed batters have an advantage against left-handed pitchers and left-handed batters benefit from facing right-handed pitchers. This is because a right-handed pitcher's curveball breaks to the left, from his own point of view, which causes it to cross the plate with its lateral movement away from a right-handed batter but towards a left-handed batter (and vice versa for a left-handed pitcher), and because batters generally find it easier to hit a ball that is over the plate. Furthermore, since most pitchers are right-handed, left-handed batters generally have less experience with left-handed pitchers. A left-handed pitcher may also be brought in to face a switch-hitter who generally bats left-handed, forcing the batter to shift to his less-effective right-handed stance or to take the disadvantages of batting left-handed against a left-handed pitcher. Platooning can be viewed negatively. Players prefer to play every day, and managers, including Walter Alston, feared that sharing playing time could decrease confidence. Mookie Wilson of the New York Mets requested a trade in 1988 after serving in a platoon for three seasons with Lenny Dykstra. History The advantage to alternating hitters based on handedness was known from the early days of baseball. Bob Ferguson, in 1871, became baseball's first switch hitter, allowing him to bat left-handed against right-handed pitchers, and right-handed against left-handed pitchers. The first recorded platoon took place in 1887, when the Indianapolis Hoosiers briefly paired the right-handed Gid Gardner and left-handed Tom Brown in center field. In 1906, the Detroit Tigers alternated Boss Schmidt, Jack Warner, and Freddie Payne at catcher for the entire season. As manager of the Boston Braves, George Stallings employed platoons during the 1914 season, which helped the "Miracle" Braves win the
