Bumgarner did not address the exchange during his postgame interview, but Gomez brought it up with reporters in the home clubhouse, unprompted.
"Who does that guy think he is, Bumgarner?" Gomez said. "I never scream at anybody when they miss a pitch and he screams at himself, or they make a pitch and be happy. I never say anything. So you put a good swing, and they're looking at you like you're a piece of [garbage]. Tell that [guy] to throw the ball and don't worry about my thing.
"That [guy] was looking at me like I'm an idiot. So you worry about pitching, I worry about hitting. I don't care what you do. You can strike me out and do whatever you want. That doesn't bother me. But a professional, like the guy he thinks he [is], you throw the pitch and the hitter can do whatever he wants. I missed a pitch. ... I was [upset] because I waited for that pitch and I'm supposed to hit it and I missed it.
"... I was [mad] at myself, so he can't be looking at me. He's not my dad."
Gomez has been sensitive to inside pitches of late after being struck three times on the Brewers' last road trip, including once in the head by Mets right-hander Noah Syndergaard. He was also hit on the right forearm in Detroit and on the right wrist in Atlanta on the same trip.
The Giants and Brewers conclude their three-game series Wednesday afternoon.
