Pittsburgh Pirates right-hander Joe Musgrove admitted his guilt and it cost him.

Musgrove was sent a letter from MLB's chief baseball officer, Joe Torre, on Monday and was handed a $1,000 fine for admitting he intentionally hit Chris Owings of the Arizona Diamondbacks last week, according to Elizabeth Bloom of the Pittsburgh Post-Gazette.

The pitcher confessed that he threw at Owings on behalf of teammate Josh Harrison, who was hit earlier in the contest between the two teams on June 11.

"That's the rules of the game," Musgrove said after receiving the fine. "If you potentially throw at guys, you're going to get fined for it. But like I said before, it's something that's been around for a long time and something I really believe in. We don't like our guys getting thrown at, especially J-Hay, who gets consistently thrown at. ... We're just looking out for our teammates, and if we got to pay the fine, we'll pay the fine, but we just want people to know that that's not something that we're going to let slide by."

Musgrove said he doesn't plan to appeal the decision.
