In fact, during his six-year professional mixed martial arts (MMA) career, "Showtime" has only gone the distance five times in 19 fights and has an impressive 14 finishes on his resume.
And the always-entertaining striker doesn't plan on letting up anytime soon.
As he gears up to defend his strap for the first time against Josh Thomson -- a concussed T.J. Grant's replacement -- at UFC on FOX 9 on Dec. 14, 2013 in Sacramento, California, Pettis says the goal is the same as he plans to finish "The Punk" when the two collide in "Sac-Town."
If that wasn't ambitious enough, Pettis aims to end the fight in the very first round, something all of his future opponents can expect when they step into the Octagon against him.
He broke it down during a recent appearance on "The MMA Hour:"
"He's 35-years-old, his last chance at a title shot and I know he's coming hard. There's no bad blood, he was calling me out before the Henderson fight, so I think he really wants the title fight bad and I'm not going to take it easy on him. I'm going to finish him just like I've been finishing everybody else. My goal is to knock you in the first round. I want to finish all of the guys in the first round. That's what I'm shooting for. I want to finish every fight. I don't want anybody going past five minutes with me."
Pettis won the title by defeating Ben Henderson -- a man not too concerned with finishing fights -- at UFC 164 in Milwaukee, Wisconsin, via first-round submission (armbar), making it three consecutive finishes for "Showtime."
In victory, Pettis suffered a knee injury during the "Brew City" brawl; however, it won't require surgery, which will allow him to be 100 percent when he faces Thomson. That means "The Punk" -- the aging veteran and former Strikeforce champ -- will definitely have to be on his "A game" if he wants to cut Anthony's title reign short.
Something he plans on doing in what could be his last chance at UFC gold.
