Brock Lesnar defeated Frank Mir in the second round of the main event at UFC 100 to become the undisputed heavyweight champion.
In their first fight, Mir caught Lesnar in a knee bar to get a tap out, but Lesnar wasn't going to let that happen this time. He took Mir to the ground several times, but maintained his poise and position to ensure Mir couldn't slip into a submission.
Lesnar also delivered a hellacious beating to Mir's face, leaving the pretty boy looking like two-day old chuck steak.
After the victory, Lesnar again created controversy with his post-fight antics. He got in a still dazed Mir's face and taunted him, flipped off the assembled fans, then proceeded to diss event sponsor Budweiser. At the post-fight press conference, Lesnar later apologized to Dana White and brandished a bottle of Bud while proclaiming that when it comes to beer, he doesn't discriminate.
