(Corrects Pacquaio record) * Mayweather says next fight will be his last * Pacquiao said he thought he had the fight won By Steve Keating LAS VEGAS, May 2 (Reuters) – Floyd Mayweather Jr. cemented his place among the pantheon of boxing greats by improving to 48-0 with a unanimous decision over Manny Pacquiao on Saturday in a fight that lived up to its immense hype and price tag. Mayweather weathered an early assault by the Filipino southpaw and then won the later rounds to finish ahead on all three judges’ scorecards in a welterweight showdown that is expected to be the top grossing prize fight of all-time. “When the history books are written, it was worth the wait,” Mayweather said in the ring after a fight that was over five years in the making. Though Pacquiao repeatedly forced Mayweather to backpedal, the wily American blunted his opponent’s best efforts by using his renowned defensive skills while getting in several telling jabs and punches of his own.
