WASHINGTON — Josh Hader‘s All-Star experience went from bad to worse.

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 offensive tweets that Hader sent when he was a teenager surfaced.

After the game, Hader apologized for his actions.

“You know, it was something that happened when I was 17 years old. 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.”

Hader said that his old messages do not reflect his current beliefs.

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

The 24-year old hurler, who appeared in the eighth inning and allowed three runs on four hits, including a three-run homer to Mariners shortstop Jean Segura, said that he wasn’t aware of the controversy until after the game.

“Just came in and my phone was blowing up. 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 on doing so.

“Yeah, for sure. It’s something that they shouldn’t be involved in. Being 17 years old, you know, you make stupid decisions and mistakes.”

The second-year player also said that he’s prepared for any discipline that might be handed down as a result of his actions.

“I’m ready for any consequences that happen for what happened seven years ago.”

Deputy Commissioner Dan Halem, speaking outside the NL clubhouse, said he had spoken to Hader. He said Major League Baseball would not have any comment before Wednesday.

Fellow Brewers All-Star Lorenzo Cain also addressed reporters postgame and revealed that, by that time, he had spoken with Hader.

“We just talked a little bit. I was just trying to understand the situation,” said Cain. “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 okay. We’ll move on from it for sure.”

The Brewers entered the All-Star break with a record of 55-43 and were 2.5 games behind the Chicago Cubs in the National League Central.

Buoyed by Hader’s standout relief pitching and the offseason signing of Cain and fellow free agent Christian Yelich, Milwaukee had been in first place for much of the season, but lost its last six games heading into the All-Star break to fall behind Chicago.

A former 19th-round pick of the Baltimore Orioles, the left-handed Hader was traded to the Houston Astros in July of 2013. Two years later, he was dealt to the Brewers right before the 2015 trade deadline. This season, in 31 games with Milwaukee, Hader is 2-0 with seven saves and a 1.50 ERA. In 48 innings, he’s recorded 89 strikeouts, most among all relievers.
