His career winding down to its final seconds, Floyd Mayweather Jr. took a victory lap around the ring, his fist raised in triumph. After 19 years of perfection in the ring, he deserved one final bow. Mayweather capped a remarkable career with a typical Mayweather fight last night, using his defensive wizardry to frustrate Andre Berto on his way to a decision so lopsided one judge gave him every round. The $32 million he earned was pocket change compared to what he got for Manny Pacquiao in his last fight. But the more important number was win No. 49 in the final fight of his unblemished career, tying the mark of the late heavyweight champion, Rocky Marciano. "You gotta know when to go. I've had a great career," Mayweather said. "I'm leaving with all my faculties. I feel like I'm smart and sharp."
Mayweather wasn't about to change what he does best. Both dominant and defensive, he used all the tricks learned in a pro career that began in 1996 to take a unanimous decision over Berto. The ringside scorecards reflected Mayweather's dominance, with one judge scoring a 120-108 shutout. The other scores were 118-110 and 117-111, while the AP had Mayweather winning 119-109. Ringside punch stats showed Mayweather's defensive wizardry. He was credited with landing 232 of 410 punches, while Berto landed only 83 of 495. "It was difficult to fight him," Berto said. "He was really, really slippery." Though most in boxing believe Mayweather will someday fight again, the 38-year-old says he has plenty of money and his health is more important than chasing records. "I've accomplished everything," Mayweather said. "I've done everything in my sport." (Read more Floyd Mayweather Jr. stories.)
