Asked in Baseball Rules and Regulations
Can you play in both leagues and win the batting title?
Yes. To win a league batting title, a player must have a minimum of 502 plate appearances. If a player has 502 or more plate appearances when he is traded to the other league and winds up in 1st place in batting average for the league he was traded from, he is awarded the league title. To win an MLB (both leagues) batting title, a player must have a minimum of 502 plate appearances combined in both leagues.
