In June 2010, we posted a list of the ten greatest fighters who had yet to take a loss. By November 2011, none of their perfect records were still intact, proving once again what a cruel bitch this sport is. Half of the fighters on our original list — Shane Carwin (#1), Megumi Fujii (#2), Ryan Bader (#6), Evan Dunham (#7), and Lyle Beerbohm (#10) — have even lost *twice* since then. So we decided to start over from scratch and come up with a new ranking of undefeated MMA fighters. Check it out, and let us know who you think will hold onto their ’0′ the longest. -BG

#9: JIMY HETTES (10-0, nine wins by submission)

Notable victories: Jacob Kirwan at MASS: Inauguration (sub R2), Alex Caceres at UFC Live: Hardy vs. Lytle (sub R2), Nam Phan at UFC 141 (UD).

Next fight: TBA; he was supposed to face Steven Siler next month, but had towithdraw last week due to injury.

We don’t like to toss around the word “prodigy” unless it’s truly warranted, but honestly, Jimy Hettes is the Little Man Tate of grappling. At just 24 years old, the Pennsylvania native is already an expert, innovator, and educator of the ground game, and submitted his first nine MMA opponents with shocking ease. The only guy he wasn’t able to finish was Nam Phan in his last UFC appearance, and even then, the thrashing he gave Phan was so lopsided that two judges scored the fight 30-25. We can’t wait to see Jimy’s run in the UFC featherweight division continue once he’s healthy again.
