Floyd Mayweather says he's riding off into the sunset, and he'll do it with a piece of boxing history.

Mayweather boxed and moved his way to an easy unanimous-decision win over Andre Berto on Saturday night at the MGM Grand Garden Arena in Las Vegas, improving to 49-0 and tying the record set by heavyweight legend Rocky Marciano.

Scores were 120-108, 118-110 and 117-111 for Mayweather, who barely broke a sweat and was never in any danger against a game but woefully overmatched opponent.

Mayweather reiterated during his post-fight comments that he would indeed be keeping his promise and calling it a career after becoming boxing's undisputed pound-for-pound king and top box-office attraction.

Berto attempted to press the action, particularly early in the fight, but he was tight, loading up on all his punches and connecting with nothing but air. He never varied his attack or changed tactics when it was clear things weren't working.

That made it easy for Mayweather, one of the smoothest and smartest defensive operators the sport has ever seen, to time him and make him pay.

Mayweather's complete and utter dominance can be seen in the punch stats.

He landed a ridiculous 56 percent of his total punches according to ShoStats, while holding Berto to just 83 connects over 12 one-sided rounds.
