Floyd Mayweather, Andre Berto make weight for Vegas showdown

Floyd Mayweather and huge underdog Andre Berto each easily made the 147-pound weight limit for Saturday`s world title showdown in Las Vegas in front of a raucous crowd.

The welterweights engaged in a 30-second faceoff after taking to the scales, setting the stage for a fight that unbeaten pound-for-pound king Mayweather has repeatedly insisted will be his last.

Victory for Mayweather, 38, will see him equal the perfect 49-0 record of legendary heavyweight Rocky Marciano for a place in the history books.

"Money" Mayweather (48-0, 26 KOs) weighed in at 146 pounds; Berto (30-3, 23 KOs), hit the scales at 145 pounds.
