Kell Brook's chances of fighting undefeated welterweight champion Floyd Mayweather got better on Saturday night, as the British star won a sixth-round technical knockout against Frankie Gavin at O2 Arena in London. 

It was a convincing victory for Brook, who delivered a series of hard right hands with Gavin backed against the ropes. As the round was coming to a close, Brook unleashed crosses, as well as some hard upper cuts to force the referee to call an end to the bout.

Gavin, a Birmingham native who entered the fight with a 22-1 record, showed promise in the early rounds, as the southpaw used some strong right hands to counter Brook. But Brook turned up the assault in the later rounds, and was able to slow Gavin with enough hard shots in the fifth round to lead into the sixth-round TKO.

"It was about being patient for a few rounds," Brook said, after the fight. "It was only a matter of time."

Brook maintained his undefeated record, and his victory over Gavin may be evidence that he is a top contender after wins over Jo Jo Dan and Shawn Porter. His wins have generally been convincing, with 24 coming by way of knockout.

However, Brook's odds of fight Mayweather might be difficult considering fellow Brit Amir Khan's victory over Chris Algieri in Brooklyn on Friday night. Brook remains confident that he can fight boxing's top pound-for-pound fighter.

"I'm ready to take on the world. I'm ready for the best out there now," Brook said, when asked about Mayweather.
