Rankings compiled by Richard Wade.
Well #1 Frank Edgar's decisive decision win over #2 B.J. Penn at UFC 118 made it official: there's a new sheriff at 155lbs. At least until Edgar defends his belt against #4 Gray Maynard at UFC 125.
Maynard jumped three spots after beating #7 Kenny Florian at UFC 118.
#10 Sean Sherk jumps five places after taking a very controversial split decision win over #12 Evan Dunham at UFC 119.
#3 Gilbert Melendez is taking some time off to have a personal life while #19 Gesias JZ Cavalcante and #21 Josh Thomson face off at Strikeforce: San Jose on October 9.
#5 Shinya Aoki fought at DREAM 16, beating Marcus Aurelio but that had no impact on his standing. It will be hard for him to find top opponents in Japan.
#6 Eddie Alvarez will face unranked Roger Huerta at Bellator 33 on October 21st. This is a fight with huge implications for the division despite Huerta's unranked status.
Alvarez owes his high ranking to his impressive run in DREAM and victories over #8 Tatsuya Kawajiri among others. His fight against Huerta will be the first chance for fans to see a fighter from the DREAM/Strikeforce pool face a fighter who has faced UFC mainstays like Gray Maynard and Kenny Florian.
Huerta's loss to Pat Curran earlier in his Bellator run somewhat diminishes the import of this bout, but hey, it's the best we're going to get for sometime to come.
