I don't see a problem with someone flipping a bat. Why does a team get so upset that they throw at a batter? Because he "doesn't respect the game"?
Hockey players celebrate every goal, basketball player mug for the cameras after every dunk, but in baseball you can't celebrate a homer?
As for Bautista, he was probably thinking "this is what you get" after that run scored in the top of the 7th. I know I was thinking it.
