A Swingman is a player who can play multiple positions and is capable all over the court.
In basketball, the term "swingman" (aka "guard-forward") denotes a player who can play both the shooting guard (2) and small forward (3) positions, and, in essence swing between the positions. Most swingmen range from 6' 4" (1.93 m) to 6' 9" (2.06 m) in height. The term was first applied to John Havlicek. Examples of current swingmen include: Paul Pierce, Jimmy Butler, Andrew Wiggins, Gordon Hayward, Nicolas Batum, Vince Carter, Andre Iguodala, Danny Green, Kyle Korver, Justise Winslow, Mike Miller, Terrence Ross, Joe Johnson, Nick Young, Tyreke Evans, Lance Stephenson, Evan Turner, C.J. Miles, Thabo Sefolosha, Arron Afflalo, Corey Brewer, and Tony Allen. Examples of retired NBA swingmen include Scottie Pippen, George Gervin, Clyde Drexler, Tracy McGrady, and Rick Barry.
In ice hockey, a swingman is a player that could play both defenseman and forward.
In baseball, a swingman is a pitcher who can work either as a reliever or as a starter; sometimes, if the pitcher is usually a long reliever, he is called a "spot starter".
