Boxing-Mayweather cements legacy with Pacquiao win (Reuters)
* Mayweather says next fight will be his last * Pacquiao said he thought he had the fight won (Adds detail, quotes) 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 from the Filipino southpaw before winning the later rounds using his reach and jab to finish ahead on all three scorecards in a welterweight showdown set 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 four-belt unification bout that was more than 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.
