Floyd Mayweather Jr. has returned to the ring in a big way with an unanimous decision over the smaller, lighter Juan Manuel Marquez.

In his first fight back from retirement and a 21-month absence, Mayweather knocked down the undersized Marquez in the second round and then peppered him with countless damaging shots to remain unbeaten in 40 pro fights.

Marquez was a 130-pounder just 18 months ago, but the Mexican champion moved up two weight classes to be Mayweather's hand-picked comeback opponent. At Friday's weigh-in, he was four pounds lighter than Mayweather, who paid a hefty six-figure penalty for missing the bout weight.

The size disparity was painfully obvious from the opening bell, but Marquez stayed on his feet for 12 one-sided rounds.
