If this was Floyd Mayweather Jr.’s last fight, he went out in dominating fashion.

Mayweather toyed with an overmatched Andre Berto en route to a one-sided decision victory Saturday in Las Vegas in what the unbeaten RING champion insisted again was his final fight.

That leaves him with a record of 49-0, which equals the mark with which late heavyweight champ Rocky Marciano retired.

Mayweather was simply far too good for Berto (30-4, 23 KOs), who had the desire but not the skill set to cope with the No. 1 fighter in the world.

The scores reflect that: 117-111, 118-110 and 120-108, all for Mayweather.

The punch stats also reflect that: Berto connected on only 17 percent (83 of 495) of his punches, a testament to Mayweather’s defensive wizardry. Meanwhile, the winner connected on 57 percent (232 of 410) of his shots overall.

That adds up to a wipeout.
