Kell Brook v Rafal Jackiewicz smaller

Kell Brook underlined his potential for the top by blasting out Argentina's Hector Saldivia in three rounds at the Motorpoint Arena in his home city of Sheffield tonight.

The unbeaten British welterweight was stung by criticism after struggling down the stretch in his July points win over America's Carson Jones.

But after changing his preparations and enlisting the services of a new nutritionist, Brook was back to his best.

It was clear that the fight wouldn't last long in the opening round. A fast one two brought about applause in the opening 30 seconds and before the round was over Brook sent the visitor to the canvas with an uppercut.

The clean punches continued to be fired home in the second, leaving Saldivia severely marked up around his right eye.

And a straight left finished things 28 seconds into the third.

It was one of those rare moments where a single jab proved to be the telling blow. Saldivia, who had been stopped twice previously, moved in and Brook punished him for it with a shot that many people wouldn't have seen.

The Argentine did attempt to get back to his feet but was wobbling and nearly feel back down before referee Howard Foster waved it off.

The victory means that Brook is now the mandatory challenger for the winner of this evening's IBF title clash between Randall Bailey and Devon Alexander.
