B.J. Penn showed once again on Saturday night that he's the best lightweight in mixed martial arts, defending his UFC title and defeating Kenny Florian with a fourth-round rear-naked choke at UFC 101.
Penn controlled the fight throughout, winning the first three rounds before submitting Florian in the fourth.
UFC middleweight champion Anderson Silva remained undefeated in the Octagon Saturday night, moving up to light heavyweight and destroying former champ Forrest Griffin, hardly even breaking a sweat before beating Griffin by first-round TKO.
After they felt each other out for the first couple of minutes, Silva landed a powerful right punch that leveled Griffin. He let Griffin up and leveled him again, then did it a third time before the referee stopped the fight.
