Chapter eight gabillion in the unwritten rules wars unfolded last night during and after the Angels-Astros game. The subject: bat flips.

The Angels beat the tar out of Astros starter Mike Fiers, lighting him up for eight runs on ten hits in three and two-thirds innings. One of the big blows against him: a two-run homer from Luis Valbuena which put the Angels up 5-0 in the first inning. In response Valbuena — who played with Fiers in Houston last year — flipped his bat, as seen in the photo above.

Fiers obviously didn’t care much for that and, in the fourth inning, threw a pitch that went a few feet over Valbuena’s head and sailed to the backstop. Home plate umpire Cory Blaser immediately warned both benches. It was clearly intentional, of course. For his part, Valbuena wasn’t rattled, as he dug back in and hit a double. He’d eventually come around to score.

After the game, Fiers took issue with the flip, saying “I took it as disrespect.” Valbeuna’s response: “I enjoyed my home run. If they want to hit me, that’s OK. But if I hit another home run, you’ll see what happens.”
