What if my player gets traded from one league to another during the season? Say, from the NL to the AL?
If a player in an AL-only or NL-only league is traded to a different league during the course of the season, you will be able to continue to use him with his new league’s stats. If you are in a keeper league, you may wish to protect him with a “crossover” spot. Most leagues allow 2 crossovers per team.
