Floyd Mayweather Says No One Came Close in His 50-0 Career
The five-division champ brushed off Mosley, Maidana and Castillo, insisting nobody ever truly threatened his perfect 50-0 ledger.

Floyd Mayweather walked away with a 50-0 record and, by his own account, never once felt like it was in danger. The five-division champion, now 49, told the PBD Podcast that no opponent in his entire professional run came close to beating him — the kind of statement that invites a highlight reel of counter-arguments.
There are a few. In 2010, Shane Mosley caught Mayweather with a right hand in round two that visibly buckled his knees. Mayweather recovered, dominated the third and cruised to a unanimous decision, but for a few seconds the untouchable aura flickered. He says the fix was simple: his corner told him to pick it up, so he picked it up.
The Nights People Point To
Mosley isn't the only name critics reach for. Marcos Maidana dragged Mayweather into a genuine scrap in 2014, with Floyd escaping on a majority decision rather than his usual wide cards. Go back further to 2002 and his first fight with Jose Luis Castillo at 135 pounds, a unanimous decision many ringside felt could easily have gone the other way.
Mayweather's response to all of it is a shrug. He framed himself as the standard the sport is measured against — his line was essentially that you can't discuss boxing without discussing him, and that if he doesn't believe in himself, nobody else will. Self-belief has never been his problem.
The McGregor Footnote
The 50th win is the one that still gets side-eye. Mayweather stopped UFC star Conor McGregor in the 10th round in 2017, a crossover spectacle that printed money but did little for his boxing legacy. It padded the record to a clean 50-0 and gave him the perfect exit number.
McGregor, for his part, hasn't fared well since. The Irishman carries a 22-7 MMA record (19 KOs, one submission) and is coming off a first-round TKO loss to Max Holloway. There's no signed bout agreement for his return. Mayweather, meanwhile, is content to retell the story his way — one where the cards were always lopsided and the drama was always manufactured.
