ATLANTA -- Atlanta Braves pitcher Sean Newcomb apologized Sunday for a series of offensive tweets he sent as a teenager, calling them "some stupid stuff."
The 25-year-old Newcomb spoke less than an hour after he nearly pitched a no-hitter against the Los Angeles Dodgers. The tweets were sent in 2011 and 2012, when Newcomb was a senior in high school.
One tweet included a racial epithet that was part of a rap lyric, and several others contained gay slurs.
"I just wanted to apologize for any insensitive material," Newcomb said. "It was a long time ago, six or seven years ago, saying some stupid stuff with friends.
"I know I've grown a lot since then. I didn't mean anything by it. It was just something stupid I did a long time ago, and I didn't mean anything by it, for sure."
Major League Baseball dealt with a similar situation this month involving Milwaukee Brewers reliever Josh Hader on the night he pitched in the All-Star Game.
"Such inappropriate comments have no place in our game. We are aware of this serious issue. Billy Bean will meet with Mr. Newcomb this week, and we will identify an appropriate course of diversity training in the Atlanta community," MLB said in a statement.
Bean is MLB's vice president for social responsibility and inclusion. He is a former big league outfielder and openly gay.
Hader apologized after offensive tweets sent when he was a teen came to light on July 17. The next day, MLB said the 24-year-old Hader will be required to go through sensitivity training and participate in diversity and inclusion initiatives. Hader also met with Bean.
"We are aware of the tweets that surfaced after today's game and have spoken to Sean, who is incredibly remorseful," the Braves said in a statement posted on Twitter. "Regardless of how long ago he posted them, he is aware of the insensitivity and is taking full responsibility.
"We find the tweets hurtful and incredibly disappointing, and even though he was 18 or 19 years old when posted, it doesn't make them any less tolerable. We will work together with Sean toward mending the wounds created in our community."
Atlanta's clubhouse had already closed to the media after Newcomb answered questions about his career-best moment, a 4-1 Atlanta victory in which he came within one strike of pitching a no-hitter. Chris Taylor broke up the bid with a two-out single in the ninth inning.
Newcomb said he had forgotten about the tweets until he picked up his phone postgame and saw mentions of the posts. The Braves reopened the locker room about 30 minutes later. Newcomb said it was his idea for a team official to bring reporters back downstairs so he could address the subject.
"This is something obviously that can't be happening," he said. "I feel bad about it. I don't mean to offend anybody. It was six, seven years ago. I didn't mean anything by it, and I definitely regret it, for sure."
Newcomb said he doesn't think the tweets will cause fallout among his current teammates.
"No, I don't think so," he said. "I think people that know me know that's not the kind of person I am. It's been a long time since then, and at the same time, I didn't mean anything by it."
Also Sunday, old, offensive tweets from Washington Nationals shortstop Trea Turner surfaced on social media. He issued a statement apologizing for the tweets.
