The plan for his second start was to go 3 innings, but he was feeling fatigued so Counsell decided to pull him after just the 2 IP. That's likely why Jackson pitched the third inning in that game and Gio didn't come in till the 4th since the plan to start the game was for him to enter in the 4th and they needed to allow him ample time to prepare. It will be interesting to see when he is used. Pitch him on Sunday if it means a chance to tie/win division? Division tie breaker? Wild card game? I think if they have the chance to win the division outright on Sunday he will pitch. I don't think there's any way he's not pitching in a division tie breaker game if he's rested.
