Mayweather V Baldomir

Floyd Mayweather made an extraordinary retirement pledge after underlining his status as the best boxer in the sport by claiming the WBC welterweight title from Carlos Baldomir.

The 29-year-old 'Pretty Boy' insists he will fight just one more time - possibly against Oscar De La Hoya in a huge showdown early next year - before quitting boxing for good.

Mayweather said: "One more fight and that is it for me. I am not in this sport for the money, I am in it for the legacy, and I have done everything I wanted to do."

Mayweather, who won his first world title in the super-featherweight division, comprehensively outboxed the come-forward Baldomir to earn lopsided 120-108 (twice), 118-110 verdicts.

Argentinian Baldomir had emerged as one of the sport's unlikely success stories with successive victories over Arturo Gatti and Zab Judah.

But the 35-year-old had no answer to Mayweather's dazzling skills and admitted: "He was too fast and I could not catch him. When I did hit him my punches were not strong enough."

Mayweather, who said he now hoped to have tempted De La Hoya into what would be one of the biggest grossing fights in boxing history, struggled with a hand injury in the later stages of the fight.

Mayweather added: "I hurt my right hand in the middle of the fight and I have not felt this kind of pain before. But I can win in any circumstance and I will fight and beat anybody."
