I guess i should have said return to the game. You will have to be the pinch hitter, or, if the pinch hitter gets a hit continue til the inning is over, do the double switch. The go back to QM.
I don't know if the AI will consider whether or not that pitcher has had time to warm up. Will it bring the pitcher in with full stamina? I would guess as there's no warm up in QM it will.
