An all-star game is an annual exhibition baseball game between two teams the purpose of which is to showcase the best and most popular players among the the teams within the subleagues or conferences that make up a particular baseball league. The competing teams are made up of players rostered solely for the event, with selections made by league officials or fans. A league's all-star game usually takes place at the mid-season point during a break in regular game play lasting 3 to 5 days, the exception being certain collegiate leagues (such as the CIS league), which plays their all-star game before the season starts.
The statistical results of an all-star game do not count towards any of the participating players season totals, and the contest is mainly held for the enjoyment of the sport by the fans, who get to watch the very best of the players compete all in one game.
