Frankie Gavin added the Commonwealth welterweight title to his British belt with an impressive seventh-round stoppage of Denton Vassell in Liverpool.
The Birmingham southpaw extended his unbeaten record to 16 fights, with 12 inside the distance, and ended Vassell's at 20 after leaving the Mancunian with a suspected broken jaw.
Vassell had defended his Commonwealth title three times in his three-year reign, the most recent against the previously undefeated Ronnie Heffron last November, but had no answers tonight in the face of a blistering performance from 27-year-old Gavin.
The British champion dominated the opening three rounds but was forced back onto the ropes in the fifth as Vassell briefly came into the bout.
Gavin was causing havoc with his trusty left hand, though, and reasserted his dominance in the next two rounds.
And a fearsome shot to the jaw saw the fight stopped, following a doctor's inspection after the seventh round.
On the undercard, Paul Butler defended his Commonwealth super-flyweight title and raised hopes of a world title shot with a fourth-round stoppage of late stand-in Najah Ali.
The Merseysider put his opponent on the canvas early on and finished him off with a brutal left hook in the fourth.
