After a bumpy outing in his first All-Star appearance, the Milwaukee Brewers reliever suddenly found himself caught up in a Twitter firestorm. Late during Tuesday night’s All-Star Game, some racist and anti-gay tweets that Hader sent when he was a teenager surfaced.

After the game, Hader apologized for his actions.

“Obviously, when you’re a kid, you just tweet what’s on your mind, and you know, that’s what’s on,” he said

The reliever, who appeared in the eighth inning and gave up three runs and four hits, including a three-run homer to Mariners shortstop Jean Segura, said he wasn’t aware of the controversy until after the game.

“Just came in, and my phone was blowing up,” he said. “You can’t, there’s no excuse for what was said. I’m deeply sorry for what I’ve said and what’s been going on, and like I said, it doesn’t reflect any of my beliefs going on now.”

Although he had yet to address the issue with any of his Milwaukee teammates, he said he planned to do so.
