In front of his hometown Milwaukee fans, Anthony Pettis needed less than a round to end the UFC Lightweight Championship reign of Ben Henderson tonight at UFC 164.

Henderson, who entered the ring in a black jiu-jitsu gi and his newly minted black belt, gained an early advantage with strikes from the clinch. But Pettis would out-land the champion when they disengaged, hitting a series of round kicks to the body. Then, Henderson was able to catch a leg and pull Pettis to the mat — where Pettis immediately attacked with an arm bar.

There was no tap, but Henderson, of Glendale, AZ, verbally submitted at 4:31 of the first round. Anthony Pettis is your new UFC lightweight champion.
