We're less than a month into the 2013 MLB season, and we've already got our first crazy bench-clearing brawl.

In the bottom of the sixth inning of the Dodgers/Padres game last night, Los Angeles pitcher Zach Greinke accidentally hit Padres left fielder Carlos Quentin with a pitch. Quentin, who has been hit by Greinke in the past, took exception to the HBP and charged the mound to confront Greinke. And, from there, all hell broke loose. Both benches cleared, Greinke and Quentin wrestled to the ground and got stuck at the bottom of a huge pile of players, and, during the melee, Greinke suffered a broken collarbone.

The brawl didn't end there, either. Shortly after the game ended, Greinke's teammate Matt Kemp confronted Quentin in the clubhouse tunnel. They were eventually separated before a physical altercation took place. But the Dodgers were understandably upset with what took place during the game.

"My teammate now has a broken fucking collarbone," said Jerry Hairston Jr., who was ejected from the game, along with Greinke, Kemp, and Quentin, for fighting. "Excuse my language, but that's unbelievable."

Check out the wild scene in the video above. Do you think Quentin was out of line for charging the mound here?
