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 tempt 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.”
Shannon Briggs claimed the WBO heavyweight title in spectacular fashion in Phoenix when he stopped champion Sergei Liakhovich with one second remaining in the final round.
Liakhovich was leading on all three judges’ scorecards and would have claimed the title by at least a split decision if he had managed to stay on his feet.
But Briggs exploded into life in the final 30 seconds of an otherwise uneventful contest, decking the Belarusian twice, the second of which left him sprawled on the timekeeper’s table and counted out.
Briggs said: “My corner kept telling me I was losing the fight. If I didn’t turn it around, they said I would lose. The Lord was looking down on me with one second left. My life has been full of ups and downs. I was homeless and now I am world heavyweight champion. Now I can go to my grave knowing I achieved something.”
