Scott Quigg made an explosive second defence of his WBA super-bantamweight title with a second round stoppage over Argentina's Diego Silva in Manchester on Saturday night.
The Bury 25-year-old floored his opponent twice, with a vicious right hand leaving Silva flat on his back on the canvas and requiring medical attention.
Quigg had been upgraded to the title earlier this year and was lucky to cling on to it last month when he squeezed a majority draw against Cuban Yoandris Salinas.
But there was no such close call for Quigg on Saturday night as he dominated the opening round behind a stiff right hand and turned on the style at the beginning of the second.
A superb right uppercut dumped Silva to the canvas and although the Argentinian gamely clambered to his feet and tried to fend off Quigg's advances, his second shot left no doubts and prompted referee Terry O'Connor to dispense with the count.
The Argentinian was helped back to his stool by medical staff while Quigg celebrated a dramatic victory which belatedly underlined his right to call himself a British world champion.
Quigg said: "A lot was said after my last fight but I definitely proved tonight that I am world level and now I want to go on and seek out big fights and try to unify the title."
Earlier, Olympic gold medallist Luke Campbell improved his professional record to four straight wins with a comfortable four-round points win over Welshman Chuck Jones.
