Following his first All-Star appearance, Josh Hader found himself involved in a Twitter controversy.

During Tuesday night's exhibition, some racist and anti-gay tweets that Hader sent when he was a teenager surfaced.

"You know, it was something that happened when I was 17 years old," he said. "As a child, I was immature, and I obviously said some things that were inexcusable. That doesn't reflect on who I am as a person today, and that's just what it is."

The 24-year-old reliever 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."

Lorenzo Cain, Hader's teammate with the Milwaukee Brewers, spoke with the pitcher about the controversy.

"We just talked a little bit. I was just trying to understand the situation," Cain said. "He was young. We all say some crazy stuff when we're young. That's one reason why I don't have social media -- for things like this. You always in trouble for things you said when you're younger. So we move on from it. The situation is what it is. I know Hader, I know he's a great guy, he's a great teammate. So I'm fine. Everybody will be OK. We'll move on from it, for sure."
