It’s been a busy month, one with the level of activity people wish they could have seen in the rematch between Fabricio Werdum and Alistair Overeem.

In the much-anticipated heavyweight showdown on June 18 in Dallas, Werdum employed the butt scoot and Overeem seldom engaged, creating a tedious fight that caused much weeping and gnashing of teeth. Overeem was able to notch the unanimous decision victory -- arguably the biggest in his career -- but hardly electrified the MMA fanbase.

Breakout performances have happened recently in the Octagon: Mark Munoz, Brian Stann and Rick Story all join the Sherdog.com rankings courtesy of recent big wins. Munoz thwarted former UFC title challenger Demian Maia, Stann bulldozed former Sengoku champ Jorge Santiago and Rick Story joined the welterweight elite with a thorough decision over Thiago Alves.

The aforementioned Story isn’t staying put, either. The next time these rankings are published, he’ll be moving and shaking in one form or fashion, as Story is set to welcome former UFC middleweight title challenger Nate Marquardt to the UFC 170-pound ranks June 26 in Pittsburgh.
