After striking out at the mound with his horrible pitch, rapper 50 Cent returned to Citi Field on Saturday (June 14) following the Mets 0-5 lost against the Padres for a post-game concert.

During his performance, Fiddy brought out G-Unit -- Lloyd Banks, Tony Yayo and Kidd Kidd -- to perform a couple of tracks. The Unit even performed their Internet-buzzing single, 'Real Quick,' which is a remix of Drake's '0 to 100.'

But things did get ugly real quick during Banks' solo performance of 'Beamer, Benz, or Bentley.'

A couple of Mets fans got into a fistfight with Padres fans in the stands. In a video shot by an eyewitness, we see one dude getting pummeled by another guy in a huge melee. And then the man's girlfriend, jumps on top of the attacker and pulls him off.

Don't blame Fiddy's music for this chaotic free-for-all. Just blame the alleged drunken Mets fans that got a little rowdy during the show. G-G-G-G-Unit!
