Floyd Mayweather vs. Andre Berto 2015: Scorecard, LIVE Round By Round Coverage

Floyd Mayweather, arguably the best boxer of his generation, defeated Andre Berto on Saturday night at the MGM Grand in Las Vegas for what he says was the last fight of his career. Las Vegas oddsmakers expected the undefeated welterweight to dominate against the heavy underdog and Mayweather didn't disappoint.

Mayweather (49-0; 26 by KO) defended his WBC and WBA welterweight titles against Berto (33-4; 23 by KO), in clinical fashion, winning convincingly on all three judges' scorecards

After the fight, Mayweather confirmed he was retiring from boxing. The Michigan native was rarely tested on Saturday and was rarely tested in his career. Nearly all of his opponents failed to win on a judge's scorecard over a professional career that spanned almost 20 years.

Berto attempted to brawl with Mayweather during stretches but found himself consistently outsmarted and overmatched by the veteran defensive specialist.

On the undercard, Roman “Rocky” Martinez and Orlando Salido fought to a draw in a rematch for the WBO super featherweight title. Badou Jack defeated George Groves for the WBC super middleweight championship. Meanwhile, junior lightweight Jonathan Oquendo beat Jhonny Gonzalez in a 10-round bout.
