FRAZER CLARKE put Esteban Bracamonte on edge to power up the British heavyweight scene.
The 30-year-old Tokyo 2020 bronze medalist looked to be at the start of a crucial learning battle, with his second professional outing against the gray Argentine.
But a bludgeoning left hook sank the South American to send a shiver through the ranks of the British giants.
Bracamonte took giant drug cheater Jarrell Miller the 10-round distance in America last month, so it was considered a tough test.
But Clarke – who will race to a British title after years as understudy to Anthony Joshua and Joe Joyce – knocked him out in just six minutes.
And the 18th Burton-On-Thames powerhouse said: “It was the left that was decisive as he was a big target to hit.
“I had to be sharp because he kept throwing that right hand which is dangerous.”
The Only Fools and Horses superfan peppered the veteran Argie all over the Bournemouth ring.
And the former Team GB skipper showed impressive defensive skills, especially for such a large unit, as the South American launched the odd haymaker back.
Big Fraze looked like he could secure an early night as he pinned Braca to the ropes and cracked a few into his slack flank, but the sturdy challenger enjoyed the shellac.
Tattooed Bracamonte continued to march his 19th frame to Clarke, shooting snot from his gnarled nose during every rare pause in the action.
The besieged visitor complained of an illegal blow to the back of the head early in the second and was given a breather to recover.
But Clarke responded by knocking him out of the ring nearly clean with a sickening shot that would send shivers down the rest of the British heavyweight scene.
