Sure there's a time to hit a guy but you don't lose the game over that. You're taking the psychology of it way too far. The Jays aren't all of sudden going to not get pitched inside because Happ hit Davis.
This isn't hockey or football where there is physical contact between 2 teams. Really doesn't matter at all what the other team thinks lol. In 2 weeks not one f***ing team will give a s*** about who hit who in this game but the team record will.
