Floyd Mayweather became a five-weight world champion and retired at 50-0 in 2017.
Floyd Mayweather began his career as a super-featherweight, and worked his way up to super-welterweight, defeating champion after champion in the process.
In his second big jump, he was left seeking a super-lightweight title in 2004, when Mayweather breezed past DeMarcus Corley before jumping into a title eliminator against a 21-2-1 foe.
Floyd Mayweather was too much for Henry Bruseles
In 2005, Mayweather faced Henry Bruseles in a WBC title eliminator. Bruseles had lost twice, once in a close majority decision and the other in a fight that was stopped due to a cut Bruseles sustained.
The fight was largely one-sided, as an impressive Mayweather continued to demonstrate his ability despite being in the higher weight class.
Mayweather forced a standing eight-count on Bruseles in the eighth round, and finished him off as he stepped back into the fray.
After the fight, according to BoxRec, Mayweather said of his measured approach: “I knew I was going to drown [Bruseles] in deep water eventually.”

2007 – Ricky Hatton – TKO10
2011 – Victor Ortiz – KO4
2017 – Conor McGregor – TKO10
