This is a savage move by Billy Butler. He wasn't happy with Chris Gimenez's frame job on a couple of pitches that made strikes out of balls. He let the Indians catcher and the umpire know about it.
Gimenez didn't like Butler complaining. Butler took the next pitch to the upper deck and had a little something for Gimenez before jogging around the bases. Pretty damn savage.
I'd put one in his earhole the next time he came to the plate, but that just me. You can do shit like this but everyone wears dresses nowadays.
