DH question (Fed)

[stumpire]

Definitely legal. Fed Rule 3-1-1 clearly stipulates all starters may be withdrawn and re-entered once. There are 10 starters. Two of them occupy the same place on the lineup card. When Baker runs for Able it kills the DH but it doesn't kill Able. He still has re-entry status. When Able returns to bat for Baker, he has re-entered and Baker is out of the game for the first time. Now Baker may re-enter. The next substitute for Able ends his playing status.
