Super featherweight
Mayweather won his first professional bout on October 11, 1996, when he knocked out fellow newcomer Roberto Apodaca in Round 2. Mayweather's trainer at the time was his uncle, Roger Mayweather; his father was still imprisoned after his conviction for illegal drug trafficking in 1993. The latter took over as his son's trainer when he was released from prison (after Mayweather Jr.'s 14th fight—a second-round knockout of Sam Girard). From 1996 to early 1998, Mayweather won most of his fights by knockout or TKO.
Early in his pro career, Mayweather received praise from all corners of the boxing world and was touted as a pugilistic prodigy. During his fight with Tony Duran the ESPN commentator remarked, "Emmanuel Steward was quoted as saying there have been very few who have been more talented than this kid. He will probably win two or three world championships; I think he will go on to be the best ever". IBHOF trainer and commentator Gil Clancy commented before Mayweather's ninth professional fight (against Jesus Chavez), "I thought that Floyd Mayweather was the outstanding pro prospect in the entire Olympic games".
In 1998, within two years of entering professional boxing, Mayweather decisively won his first world title (the WBC super featherweight (130 lb) championship) with an eighth-round technical knockout of The Ring world #1-ranked super featherweight Genaro Hernández after his opponent's cornerman stopped the fight. It was Hernández' first defeat in that weight class; he said after the fight, "He defeated me, he is quick, smart and I always knew he had the speed. I give him respect. He is a true champ".
With Mayweather's win he became lineal champion of the division; Genaro Hernández had previously beaten Azumah Nelson, whose dominance of the super-featherweight division had prompted boxing publications to give him the vacant lineal championship.
Mayweather became the first 1996 U.S. Olympian to win a world title. Following his victory Mayweather's promoter Bob Arum said, "We believe in our heart of hearts that Floyd Mayweather is the successor in a line that starts with Ray Robinson, goes to Muhammad Ali, then Sugar Ray Leonard...We believe that he epitomizes that style of fighting".
After capturing the title Mayweather defended it against contender Angel Manfredy with a TKO in round two, giving Manfredy his first defeat in four years.
By the end of 1998 Mayweather was ranked by The Ring as the #8-ranked pound-for-pound best boxer in the world, and became one of the youngest recipients of The Ring's Fighter of the Year award (21, the same age Sugar Ray Robinson and Muhammad Ali were when winning their first awards).
In 1999, Mayweather continued his domination of the super featherweight division by defending his title three more times. The second defense of his title was against the Argentine Carlos Rios, which he won in a unanimous decision. Mayweather, fighting past the eighth round for only the third time in his career, won on the judges' scoring 120–110, 119–108, and 120–109.
Mayweather's third title defense was against Justin Juuko, which he won via knockout in the ninth round. Juuko could not beat the count of 10 by referee Mitch Halpern, and the fight ended in Mayweather's favor 80 seconds into that (the ninth) round. His final title defense in 1999 was against Carlos Gerena, with Mayweather winning in a seventh-round referee technical decision (RTD). Mayweather said after the fight, "I want to show the world that along with Oscar De La Hoya and Roy Jones Jr., I'm the best fighter in the world". This dominance did not go unnoticed in the boxing world; by the end of the year, the 22-year-old Mayweather was ranked The Ring's #2 pound-for-pound best boxer in the world (behind Roy Jones Jr.).
Before making the fifth successful defense of his title against former WBC Featherweight Champion Gregorio Vargas in early 2000, Mayweather fired his father as his manager and replaced him with James Prince. A few months after the fight, the rift between father and son grew when Mayweather also fired the elder Mayweather as his trainer. In a 2004 interview Mayweather said that although he loves his father, he had a better chemistry with Roger because his father had put too much pressure on him to be perfect. Mayweather, in his fifth title defense, won a near-shutout over "Goyo" Vargas in Las Vegas. During the 10th round, when Mayweather overheard HBO announcer Jim Lampley say that the champ had switched to a southpaw stance for the second time in the bout he leaned ringside and said "It was the third time". After a six-month layoff, Mayweather was still elusive. During the sixth round, Mayweather dropped Vargas with a hook to the ribs and cruised to a unanimous decision.
Roger Mayweather returned to his role as his nephew's trainer for his next bout; a non-title lightweight fight against Emanuel Augustus (then known as Emanuel Burton), which Mayweather won by ninth-round technical knockout. Years later, in an interview in 2012, Mayweather would name his fight against Augustus as the toughest of his career, and said, "If I was rating certain fighters out of every guy that I fought, I'm going to rate Emanuel Augustus first compared to all the guys that I've faced."
In one of the more definitive and memorable fights of his career Mayweather fought the hard-hitting, former IBF super-featherweight champion Diego Corrales (33–0, with 27 KOs). Coming into the bout Mayweather and Corrales were undefeated, and neither fighter had touched the canvas. Mayweather was The Ring's #2-ranked super featherweight in the world (and #7 pound-for-pound), while Corrales was the #1-ranked super featherweight in the world and #5 pound-for-pound. Before the fight was announced Mayweather had stated he wanted to fight Corrales, who was facing jail time for allegedly beating his pregnant wife. "I want Diego because I'm doing it for all the battered women across America", Mayweather said. "Just like he beat that woman, I'm going to beat him".
While both fighters were the same age (23), Corrales had several physical advantages over Mayweather: two inches in height, an inch in reach and (despite both arriving at the official weight-in at the 130-lb super-featherweight limit) unofficially 146 lbs, versus Mayweather's 1361/2 lbs. In the bout, Mayweather won every round and knocked down Corrales five times (three times in round 7 and twice in round 10). After the fifth knockdown, Corrales' cornermen climbed onto the apron and stopped the fight, thereby establishing Mayweather as a claimant to boxing's mythical pound-for-pound title. At the time of the stoppage, Mayweather was ahead on the scorecards, leading by 89–79, 90–79, and 90–78. Throughout the fight, HBO commentators analyzed Mayweather. Larry Merchant stated, "Mayweather fights in a tradition of boxing and quick handedness that goes back in Michigan, all the way to fighters like Sugar Ray Robinson". Harold Lederman remarked, Jim (Lampley), I gotta tell ya, I'm terribly impressed, I don't think I've seen an exhibition of boxing like this since Willie Pep, this kid is unbelievable, great legs, great speed, unbelievable ring-generalship. I mean he's got tremendous presence in that ring, Floyd Mayweather knows where he is, every minute of this fight...
Corrales landed 60 of 205 punches, and landed no more than nine punches in a single round. Mayweather landed 220 of 414 punches. Corrales was unable to land any clean shots, as he stalked Mayweather through the early rounds. He landed an average of six punches a round, according to CompuBox stats—the first time that a fighter registered single digits on CompuBox, 20 years after it had been tracking punch statistics.
After the fight, Mayweather remarked, "I would like to fight Prince Naseem (Hamed), hopefully we can meet at 128 (lbs) or he can come up to 130 (lbs), we can fight or I can fight the winner of Casamayor..." "Prince Naseem isn't going to fight you," intervened HBO commentator Larry Merchant; who then chuckled and added: "after he saw this, it ain't gonna happen".
"I really want to fight Prince Naseem..." Mayweather continued, "but hopefully I can face the winner of Casamayor (vs.) Freitas". Although neither fight materialized, Mayweather's opponent Diego Corrales would later hand Freitas (the winner of the Casamayor vs. Freitas fight) his first professional defeat and defeat Casamayor via controversial decision in a rematch of their first bout. Afterwards, Bob Arum was ecstatic about his new star. "Better than Sugar Ray Leonard", he asserted. "And did you see him at those press conferences...?"
The fight was met with acclaim in the boxing world and sports in general. CBS said, "Floyd Mayweather Jr.'s speed was dazzling. His power was unexpected" and the BBC reported on "... a near flawless performance...". The New York Daily News reported that "Floyd Mayweather Jr., displaying blazing speed and punishing power..." and Sports Illustrated reported "... a fistic masterpiece".
On October 10, 2001, boxing trainer Eddie Futch died at age 90. Tim Smith of the New York Daily News remembered an encounter with the trainer in an article.
One of the last times I saw Futch was before the Floyd Mayweather Jr.–Diego Corrales junior lightweight title bout in Vegas. Futch was talking about how much he admired Mayweather's style, how Mayweather was such a beautiful boxer, able to slip along the ropes and avoid punches. Corrales said he was going to neutralize Mayweather's hand speed by hitting Mayweather on the arms. "I guess he thinks he's going to stand there and let him hit him on the arms all night," said Futch, who correctly predicted that Mayweather would completely dismantle Corrales in a defensive masterpiece. Futch had a way of cutting to the heart of a matter. I don't know anyone in boxing who won't miss him. I don't know anyone in boxing that can take his place.
On May 26, 2001, Mayweather, fighting in his hometown of Grand Rapids, pounded out a 12-round unanimous decision over future IBF super featherweight titleholder Carlos Hernández to retain his WBC super-featherweight title. Calling it "one of the toughest nights of my career", the 130-pound champion overcame injuries in both hands to improve his record to 26–0. "He is a very, very tough fighter," Mayweather said of the challenger, whose record fell to 33–3–1. "I'm disappointed in my performance." Mayweather suffered the first knockdown of his career when he hit Hernández with a left hook in round six, which caused him sufficient pain that he dropped his injured left hand to the canvas. He wasn't hit, but was given a standing eight-count by the referee.
Mayweather's last fight in the super-featherweight division was against future super featherweight and lightweight titleholder Jesús Chávez. Chávez was the WBC's top-ranked contender and came into the fight with a 31-bout winning streak. This was Mayweather's eighth defense of the WBC super-featherweight title, which he had held for more than three years. He won when Chávez's corner stopped the fight after round nine. Mayweather had such difficulty making weight for this fight that he did not eat for four days before the weigh-in. Chávez stated after the fight, "He's [Mayweather] the champ! And now I become his number-one fan".
Mayweather commented after the fight, "Although it will take some time to make the match, I want to fight Kostya Tszyu". Tszyu, an Australian-based Russian, by then had established himself as the best light welterweight in the world. Mayweather did not get a chance to fight Tszyu, but went on to fight Ricky Hatton (who defeated Tszyu and won his Ring light welterweight championship). By the end of 2001, Mayweather was still ranked The Ring #1 super featherweight and #5 best pound-for-pound boxer in the world.
