An All-Star is a player selected to play in the All-Star Game. The starting position players for each team are voted in by the fans and the rest of the team is selected by the manager for that league's team.
The term can also refer to any outstanding player. All-Star teams of various stripes are selected all the time, including for historical eras before the creation of the All-Star Game.
