Former world amateur champion Frankie Gavin produced the best performance of his short professional career with a seventh-round stoppage of former British title challenger Michael Lomax at York Hall.
Birmingham native Gavin, 25, has now won all nine of his paid fights so far and was in his first scheduled 12-round contest in Bethnal Green on Saturday.
While he had to go beyond six rounds for the first time, he did so with a near punch-perfect performance against former Prizefighter champion Lomax, combining trademark speed in both attack and defence to outclass the late stand-in.
Lomax (now 17-4-1) was in the opposite corner after Gavin's two previous opponents pulled out this week but was in shape having already been training for a fight.
Yet he had no answer to the smaller Gavin's technical brilliance and was losing convincingly, before a superb left hook landed hard and the end came late in the seventh round as Lomax's corner threw the towel in with their man taking heavy fire.
"I told Frank (Warren, promoter) I just wanted to fight," Gavin told Sky Sports 1. "Anyone in Europe, at light-welterweight or welterweight. I guarantee I'll beat any light-welterweight in Europe."
On the same bill, heavyweight John McDermott breathed new life into his career with a stunning first-round knockout win over Larry Olubamiwo.
Londoner Olubamiwo had built up a reputation as a big puncher, but it was McDermott who made his power tell during the dramatic opening round, and the Hackney man was dropped twice before the fight was waved off.
