I've never been in a MLB dugout during the game and never heard a in game conversation between an ace and hall of fame manager so maybe I'm missing something. But it seems like someone, pitching coach or manager walks over to the pitcher after 90 +pitches and asks what ya got left?
And your trying to keep a roster spot guy might lie and say give me the ball but Gio should be able to say I'm gassed.
Sending him out wasn't a bad decision, I'm more concerned that there was a startling horrible lack of communication between Gio and the coaching staff.
