Baseball Games

One man could play for two different major league baseball teams in the same day, play the entire game, and not violate any major league baseball rules. How could he do it?

He's the Ref. ?

he gets traded after the first game?

Answer

The man could play for both teams in a double header. First he plays for team A against team B, then he is traded in between games, and then plays for team B against team A.
