UFC 158: St-Pierre vs. Diaz is now in the books, and it's time to rank the welterweights after one of the most important nights in the division's history.
Georges St-Pierre took care of business in the main event, controlling Nick Diaz in typical GSP-like fashion, grinding him down with some impressive ground-and-pound while also making use of his jab on the feet. In the end, even Diaz couldn't deny that the champion deserved to keep his title.
In other welterweight contests, the UFC return of Nate Marquardt fell short as he was knocked out by Jake Ellenberger. Johny Hendricks also solidified himself as the top contender at 170 pounds after earned a unanimous-decision win over former WEC champion and UFC interim champion Carlos Condit.
The welterweight division has been in constant shift for months, but we now have a much better idea of where the fighters stack up. Here are the updated rankings following UFC 158.
