Floyd Mayweather Jr. vs. Carlos Hernández was a professional boxing match contested on May 26, 2001, for the WBC super featherweight title.

[1] Entering the fight with what he called "two messed up hands", Mayweather nonetheless overcame his injuries to win a lopsided unanimous decision.

Pressing forward throughout the fight, Hernández threw over 100 punches more than Mayweather, but Mayweather's defense held him to landing just 172 of the 676 punches he threw for a 25% success rate while Mayweather landed at a much higher rate, scoring 241 of 520 punches, Mayweather was effective with the jab, which, due to his injured hands, he threw from both his natural orthodox stance and the southpaw stance, landing 63 compared to Hernández, who only managed to land 7.

Following the injury to the sixth, Mayweather switched between orthodox and southpaw and peppered Hernández with jabs and combinations through the final round.

[2] Mayweather called the fight "one of the toughest nights of my career" and praised Hernández as a "very, very tough fighter" though he admitted to be "disappointed" in his performance which blamed on the injuries to both hands.
