Floyd Mayweather has had an unblemished career with a record of 41-0, with 25 of those wins coming by way of knockout.

With his upcoming fight against welterweight upstart and WBC champion Victor Ortiz, Mayweather will look to add not only one more win to his already impressive tally but also one more KO to add to the highlight reel.

Here are the four greatest KO's of Mayweather's long, illustrious career.

TKO of Angel Manfredy in 1998

After winning his first title as a professional boxer a fight earlier, Floyd Mayweather took on Angel Manfredy, defending his WBC super featherweight world title on December 19th, 1998.

Mayweather made quick work of Manfredy, landing a steady array of punches in the short two-round fight.

The fight was stopped after Mayweather landed punches at will to little defense on Manfredy's part, giving Mayweather the TKO win and successfully defending his first title as a pro.

First-Round KO of Bobby Giepert in 1997

Floyd Mayweather gave Bobby Giepert the KO of his career in their April 12th, 1997 bout at the Thomas and Mack Center in Las Vegas, Nevada.

Mayweather KO'd Giepert in the first round of their scheduled six-round fight, making quick work of his opponent that night.

The fight continued Mayweather on the path to super stardom and grew the buzz around his name even more.

TKO Against Phillip N'dou in 2003

Phillip N'dou gave Floyd Mayweather a good fight for most of the six rounds of their lightweight title fight on November 1st, 2003 at the Van Andel Arena in Grand Rapids, Michigan.

Mayweather eventually became too much for N'dou to handle, and N'dou was dropped by three straight powerful right hands in Round 7.

After N'dou got back to his feet at the eight count, he said he wanted to continue, but he ended up walking away from the action to the opposite corner and was obviously out on his feet.

Mayweather's win gave him his 31st win in a row, retaining his WBC and The Ring lightweight titles.

TKO Against Ricky Hatton in 2007

On December 8th, 2007 two of the top welterweights in the world put their undefeated records on the line as Floyd Mayweather and Ricky Hatton met at the MGM Grand Garden Arena in Las Vegas.

Mayweather dominated the fight from the starting bell and eventually ended the scheduled 12-round fight in the 10th round with a stunning TKO victory in front of a heavily Hatton-favored crowd.

The TKO win over Hatton gave Mayweather the marquee win that many critics felt his career was missing. Winning the fight in such a dominating fashion quieted most of Mayweather's critics—for a little while anyway.
