You see Bautista looking at the pitcher for a split second. That's him saying, "Am I pissed at this pitcher? No, man. I'm pissed at THE FUCKING UNIVERSE" and flipping the bat accordingly. Hopefully he hit the universe in the eye. Good for him.
Think of where Bautista came from. He came up with the '04 Orioles, who were garbage. They said, nah, don't need you. So they sent him to the '04 Rays, who were unimpeachable garbage. They passed. No thanks. He traveled to the '04 Royals, one of the bigger shitstorms in the last 20 years, and they traded him after a month. He was on the Mets for a day -- literally a day --- before he moved to the Pirates, who were a dirigible accident of a franchise back then.
The worst teams in baseball didn't want him. Then he became a six-time All-Star. And you're telling him that his first chance in the postseason, his first chance to play deep into October, is going to be ruined because of a technicality? He wasn't flipping the bat at the Rangers. He was flipping the bat at the technicality.
