It was a one-sided beating by Sonnen, who completely outclassed Stann on the ground and forced him to tap to an arm-triangle choke at 3 minutes, 51 seconds of round 2.
But the real news came after the fight when Sonnen demanded a rematch with the man who defeated him in his last fight, UFC middleweight champion Anderson Silva.
"Anderson Silva, you absolutely suck," Sonnen said. "Super Bowl weekend, the biggest rematch in the history of the business. I'm calling you out, Silva, but we're upping the stakes. I beat you, you leave the division. You beat me, I will leave the UFC forever."
Sonnen showed after the fight that he's a good talker, but he showed during the fight that his wrestling is as good as anyone's in MMA. Sonnen came out fast and clinched with Stann immediately, and after working at it for a little more than a minute, Sonnen secured a takedown and got into side control. From there it was a dominant round for Sonnen: He relentlessly beat on Stann on the ground, and Stann was able to do nothing about it.
Within five seconds of the second round, Sonnen jumped on Stann again and dominated him. The referee stood the fight back up midway through the second round, and Stann briefly hurt Sonnen with a couple of punches, but that was just a speed bump for Sonnen, who picked Stann up, slammed him down, and finished him off.
And with that, Sonnen's long-awaited rematch with Silva is just a matter of time.
