Sherdog Official Mixed Martial Arts Rankings

Welterweight

1. Georges St. Pierre (18-2)
Despite debate over the improper use of Vaseline by St. Pierre’s cornermen, “Rush” destroyed B.J. Penn in their Jan. 31 superfight at UFC 94. The bout reinforced St. Pierre’s case to be considered the top pound-for-pound fighter in the game, and he’ll have another chance to bolster his case against a brilliant opponent when he meets Thiago Alves, most likely at UFC 100 in July.

2. Thiago Alves (16-3)
His noted 2008 breakout has earned him a shot against St. Pierre, probably at UFC 100 in July. However, if his in-cage meeting with St. Pierre at UFC 94 told us anything, it’s that the “Pitbull” will not be the crowd favorite against the budding Canadian superstar.

3. Jon Fitch (18-3, 1 NC)
Jon Fitch will have the chance to atone for the indiscretions of teammate Josh Koscheck, as he'll take on his AKA compatriot's upset author Paulo Thiago at UFC 100 on July 11.

4. Jake Shields (22-4-1)
With no forthcoming opposition at 170 pounds, the former EliteXC welterweight champ will step up to 185 pounds to take on standout middleweight Robbie Lawler in the headliner of Strikeforce's second Showtime effort on June 6.

5. Martin Kampmann (15-2)
Kampmann gutted out a split decision victory over Carlos Condit on April 1, and with his victory, Denmark's top MMA export firmly entrenched himself amongst the top 170-pounders in the world.

6. Karo Parisyan (18-5, 1 NC)
It will be a long 2009 for Karo Parisyan. After getting popped for painkillers following his Jan. 31 split decision win over Dong Hyun Kim, Parisyan's win was stripped, and now "The Heat" will serve a nine-month suspension.

7. Paulo Thiago (11-0)
He is gutsy, if nothing else: having aced his February UFC debut against Josh Koscheck, the relatively unknown Brazilian will now attempt to knock off Koscheck's teammate and consensus top-three welterweight Jon Fitch at UFC 100 on July 11.

8. Josh Koscheck (12-4)
Following his shock upset loss to Paulo Thiago in February, Koscheck was scheduled for comeback duty against tough Chris Wilson at UFC 98 in May. Unfortunately, the TUF alum was forced out of the bout due to a foot injury.

9. Carlos Condit (22-5)
A victory was not in the cards for Condit in his UFC debut, but his wildly entertaining April 1 split decision loss to Martin Kampmann did show that the former WEC champ belongs in the Octagon with the sport's top 170-pounders.

10. Matt Hughes (42-7)
The former welterweight ruler continues to recover from a knee injury. His long-delayed grudge match with fellow former UFC welterweight champion Matt Serra will finally take place at UFC 98 on May 23 in Las Vegas.

Other contenders: Marcus Davis, Dan Hardy, Jay Hieron, Mike Swick, Nick Thompson.

*With the entry of Martin Kampmann, previously No. 10 ranked Nick Thompson slips outside of the top-10.
