And in the classic striker vs. grappler clash, the striker won out, with Siver gaining the advantage on all three judges scorecards to take home the unanimous decision win (29-28, 30-28, 30-27).
While both fighters claimed beforehand they had plans on ending the fight via submission, the bout never spent a single second contested on the floor.
That's because Siver stuffed every takedown attempt from "Sots" throughout all three rounds, even channeling B.J. Penn at one point, hopping around on one leg and landing punches on his frustrated opponent.
As it were, the opening frame told the tale of the fight. Simply put, Sotiropoulos just could not hang with the superior boxer.
Siver nearly ended the fight in the first round with two gigantic left hooks that put his Australian counterpart on his ass and had him seeing tweety birds.
But Sotiropoulos didn't want to disappoint his hometown crowd and survived to round two, where he made a small comeback. And although he may have taken round two on one of the judges scorecards, he didn't do enough to convince the others he was the better man tonight.
That's because he wasn't.
At the two minute mark of the third, Siver turned up the heat to put an emphatic end to the impressive winning streak "Sots" had put together since joining the UFC.
Is the German ready for a title eliminator bout sometime soon?
