LAS VEGAS - Marcos Maidana did everything but beat Floyd Mayweather Jr., taking him 12 tough rounds before losing a majority decision.
Mayweather remained unbeaten Saturday night (46-0), but not by much.
Maidana swarmed all over him from the opening bell and gave him perhaps his toughest fight in a 16-year professional career.
In the end, though, Mayweather got the win - just as he did in his previous 45 fights.
He retained his welterweight titles, winning the fight on two scorecards while a third judge had it even.
