The Unbeaten Phenom Moves Up
On April 20, 2002, a 25-year-old Floyd Mayweather, then known as “Pretty Boy,” was already a 27-0 superstar and the super featherweight champion. He decided to move up to the 135-pound lightweight division to challenge the reigning WBC champion, José
Luis Castillo. Castillo was everything Mayweather wasn't: a rugged, relentless Mexican brawler known for his punishing body attack and granite chin. While Mayweather was the 4-to-1 favorite, Castillo was seen as the first true test of his durability in a heavier weight class. The stage was set at the MGM Grand in Las Vegas for a classic clash of styles: the matador versus the bull.
A War of Attrition
In the early rounds, the fight went according to the Mayweather script. He used his blinding speed and defensive wizardry to outbox Castillo from the outside, sweeping the first four rounds on all three judges' scorecards. But Mayweather later revealed he had injured his rotator cuff just days before the fight, and it began to show. From the middle rounds on, Castillo effectively cut off the ring, pinning Mayweather against the ropes and battering his body. Castillo was the aggressor, visibly walking Mayweather down and landing the heavier, more impactful punches. The crowd roared with every thudding shot Castillo landed, sensing a dramatic shift in momentum.
The Verdict and the Uproar
When the final bell rang, both men raised their arms, but the feeling in the arena—and on the HBO broadcast—was that Castillo had done enough to retain his title. HBO’s unofficial scorer, Harold Lederman, had the fight 115-111 for Castillo. So when the official scores were read, the crowd met them with a chorus of boos. The judges saw it unanimously for Mayweather: 116-111, 115-111, and 115-111. Mayweather was the new lightweight champion, but for the first time in his professional career, his victory felt anything but certain. The debate began the second the scores were announced and hasn't stopped since.
The Case for Castillo
Arguments that Castillo was robbed are compelling. He was the effective aggressor for two-thirds of the bout, dictating the pace and location of the fight. The punch stats, often a source of debate themselves, heavily favored him. Compubox numbers showed Castillo out-landing Mayweather in both total punches (203 to 157) and, more significantly, in power punches (173 to 66). Fans who value aggression, work rate, and damaging blows overwhelmingly believe Castillo was the rightful winner. They argue that Mayweather spent too much time on the defensive and was visibly troubled by Castillo's relentless pressure, which should have been rewarded on the scorecards.
The Case for Mayweather
The defense of Mayweather's win rests on the core tenets of boxing's scoring system: clean, effective punching. While Castillo threw more and with more power, Mayweather’s supporters argue that many of those punches were caught on the arms and gloves. Mayweather, despite his injured shoulder, was far more accurate. His counter-punching was sharp, and his ring generalship, especially in the early rounds, was superb. Those who scored it for Mayweather believe the judges correctly rewarded the “sweet science” over brute force, valuing the cleaner, more precise shots from the challenger over the champion's often-blocked aggression.
The Aftermath and the Rematch
To his credit, Mayweather didn't ignore the controversy. Acknowledging the public's perception, he granted Castillo an immediate rematch in December 2002. In the second fight, Mayweather was healthier and better prepared for Castillo's style. He used his movement more effectively, fought at a smarter distance, and won a clearer unanimous decision. For some, this settled the score. For others, it did little to erase the memory of that first April night, when the man who would become known as “The Best Ever” looked, for 12 hard rounds, like he had finally been beaten.
