In all honesty, he was chirping early and the ump did give him a warning. Was it a weak ejection, absolutely. I hate nothing more than an umpire/ref trying to big time the situation, which is what he did. Ump was definitely in the wrong and wasn’t consistent at all.
On the other hand, why would the coach risk getting on the umps bad side in the biggest game of the year! Dude has to know the situation and control himself. He cost his kids the game, no doubt. Had his ace on the mound and the kid got rattled. Will be an interesting game tomorrow for sure!
