Silva was getting dominated in Round 1, as Sonnen connected with a great takedown, a testament to his wrestling.
Sonnen administered the ground-and-pound and although the referee was calling for work, Sonnen worked the whole time, getting himself into half guard and then mounting the champion with a minute to go.
It was a completely different Silva in Round 2, as he displayed excellent takedown defense and when Sonnen realized he was in a striking war, Silva started his trademark head movement.
Sonnen made a huge error, attempting the spinning back fist and Silva capitalized, finishing the trash-talking Oregon native with a knee to the sternum and a flurry of punches.
