Great Britain’s Ben Whittaker marked his American debut with an impressive second-round victory against Richard Rivera at Barclays Center in Brooklyn.

The flamboyant Whittaker dropped the American at the end of the first round with a right hand, although Rivera pointed that the punch had caught him on the back of the head.

But Whittaker, nicknamed ‘The Surgeon’, clinically caught his rival with a left-hander at the start of the second and, although Rivera staggered to his feet, the referee stopped the light-heavyweight bout.

The win improved Whittaker’s record to 12 wins and a draw from his 13 professional fights, while Rivera suffered the third defeat of his 30 fight career.

“Brooklyn, that’s how you do it man,” said Midlands boxer Whittaker, who is renowned for his showboating and did a little dance at the end of the first round on the way back to his corner.

The fight took place on the undercard of Xander Zayas, who attempted to defend his WBA and WBO super-welterweight titles against Jaron Ennis.

But Zayas succumbed to a seventh-round stoppage, with the referee ending the contest after the Puerto Rican boxer had been knocked down for a third time in the fight.

It was the first defeat Zayas had suffered in his 24-fight career, while unbeaten American Ennis has 36 wins from as many fights.
