DH Re-entry
 

Sit: Team A is DHing for pitcher in the 4 hole. Team A has the DH come into pitch. I know that the DH is now dead and that if he is subbed for that he has reentry eligibility. My question is can the pitcher that the DH came in for eligible for reentry under FED rules.

If he is a starter, yes. Any starter may re-enter the game once.
