This seems like a divisive topic for whatever reason.
Baseball's "old guard" seems to dislike the idea of a player flipping their bat ten feet in the air and disrespects the pitcher. Meanwhile, you have pitchers like the Dodgers' Kanley Jansen who said after the game "You can do whatever you want to if you hit me out, I don’t care. You got me."
(Then you have Yasiel Puig who went the other direction and overtly set the bat down after glancing at the pitcher.)
Personally, I love it. I love it so hard. It's a great moment. Baseball is supposed to be fun and, to me, this is a way of expressing that. So, what do you think? Where do you stand on the idea of bat flipping?
