Love him or hate him, B.J. (The Prodigy) Penn cemented his status as the top lightweight in the world last night at UFC 107.

For five rounds, he dominated title challenger Diego (Nightmare) Sanchez at every turn.

After dropping Sanchez (21-3) with a heavy straight-right and almost finishing him in the early going, Penn (15-5-1) settled into a groove that gave his opponent absolutely nothing to work with.

Whenever Sanchez charged forward, Penn made him pay, tagging him with stuff punches. If he looked to hang back and counter-strike, Penn’s attack would send him reeling. With nothing working for Sanchez in the stand-up exchanges, he opted to get the fight to the mat. However, this proved unsuccessful, as Penn stuffed every attempt.

With only a few minutes left in the fifth round, Penn turned up the heat, cracking Sanchez’s forehead open with a head kick that spelled the end of the bout. The cut was easily one of the nastiest seen in the UFC since Marvin Eastman’s grotesque gash courtesy of Vitor Belfort at UFC 43. (Click here to see a photo of Sanchez's cut -- you've been warned.)

With another impressive win under Penn’s belt, the list of lightweight title challengers is ever shrinking.

At the top of the heap are Gray Maynard (8-0) and Frankie Edgar (11-1). While both fighters possess great skills, they will certainly have their work cut out for them against Penn. Though there are a number of top lightweights in Japan -- namely DREAM champion Shinya Aoki (22-4) -- it seems unlikely they’ll appear in the UFC anytime soon.

MIR DESTROYS KONGO

Former heavyweight champion Frank Mir gave one of the most impressive performances of his career at UFC 107, putting Cheick Kongo to sleep with a guillotine choke in just over one minute.

Going into the bout, Mir (13-4), a submission specialist, raised some eyebrows by claiming he’s the superior boxer. However, his words proved true last night. Soon after the bell rang, he dropped Kongo (14-6-1) with an overhand left before sinking in the submission.

In what almost seems like an unhealthy obsession, Mir wasted no time in stating his desire for a rubber match with ailing heavyweight champion Brock Lesnar (4-1).

FLORIAN REBOUNDS

Following a tough loss to lightweight champion Penn, Kenny (KenFlo) Florian returned to form by submitting Clay (The Carpenter) Guida with a rear-naked choke in the second round of their bout.

Looking tense and tentative at first, Florian (12-4) found his groove half-way through the first round. As he opened up his striking, he stunned Guida (25-11) with a straight-right before slipping in the choke.

The time seems right to sign a rematch between Florian and Sanchez.

UFC 107 BONUSES

Alan Belcher (15-6) and Wilson Gouveia (12-7) each netted $65,000 after their bout was named “fight of the night.” The two put on a back-and-forth battle before Belcher overwhelmed Gouveia to earn the TKO victory.

Halifax welterweight T.J. Grant’s (15-3) TKO win over Kevin Burns (7-4) earned him the $65,000 “knockout of the night” bonus, while Damarques Johnson (10-7) grabbed $65,000 for “submission of the night” after slapping a triangle choke on Edgar Garcia (7-2).
