Luke Campbell maintained the perfect start to his professional career with an eighth-round stoppage of Scott Moises.
The Olympic gold medallist was made to work for his fifth straight win and gradually picked apart Moises before ending the fight in the final round with a ruthless assault.
Campbell made a confident start and a flurry of punches forced Moises to cover up on the ropes, while a straight left made him totter backwards.
Another lightning left from Campbell caught Moises unawares in the second, sending him crashing down by the ropes, but he swiftly rose and bobbed away from a barrage of punches.
Moises wore a permanent grin, appearing to almost enjoy the steady punishment, and Campbell dug in spiteful body shots in the third.
A looping left knocked Moises off balance in the fourth, drawing blood from his nose, but still he grinned and answered with a rare right hand in the fifth.
Campbell showcased some stinging combinations in the sixth and Moises briefly sagged under a body shot in the seventh as he soaked up yet more punches.
His stubborn resistance was finally broken in the final round when two lefts shook Moises to his boots before a brutal body shot dumped him on the canvas.
Moises bravely clambered to his feet, but Campbell was waiting to finish off his stricken foe and a few more punches forced the referee's intervention.
"All credit to Scott Moises, he's very, very tough," said Campbell.
"He was very tricky, hard to pin down, to land a clean shot. It was a tricky fight, but I just stuck to my shots nicely and didn't rush in. I got him there in the end."
