During the first game of a double header against the Chicago White Sox at Target Field on Friday, Twins reliever Jared Burton landed what looked like one heck of a sucker punch on fellow pitcher Brian Duensing in the Twins bullpen.

As TV cameras followed a home run ball off the bat of Twins outfielder Chris Colabello, Brian Duensing jumped up and shouted at Jared Burton; encouraging Burton to go ahead and punch him. Burton obliged, delivering the following shot to the face.

Turns out the "fight" in the bullpen was a prank the relievers had been planning for some time, and finally decided to execute it during the eventual win against the White Sox. I suppose when your team is well out of playoff contention and on track for another 90+ loss season, you need some way to pass the time in the bullpen.
