Chantelle Cameron united the WBC and IBF Ultra Lightweight titles by defeating Mary McGee with the leading points at The O2.
The 30-year-old had an edge over McGee, her right-hander landing a regular on the American as she took a unanimous 100-90, 99-91, and 99-92 victory.
On the bottom card, Croatian heavyweight Alan Babic extended his run of 10 consecutive knockouts with a quick win over Eric Molina.
Molina put up little resistance after falling to the ground for the first five seconds, then shriveled on the canvas over and over before the fight was halted in the second round.
Earlier in the evening, heavyweight Johnny Fisher extended his undefeated record to four wins with a second-round victory in an injury stop.
He brought down the Spaniard “Romford Bull” on three occasions before the referee waved at him.
Craig Richards also suspended Marek Matega in the sixth round to bring himself back into contention for another world title.
The south Londoner, who lost on points to WBA champion Dimitri Bevol in May, hit his Polish opponent with a sustained attack to force the referee to intervene.
But Youssef El Khumri’s unbeaten record ended with a majority decision loss to Jorge David Castaneda who won the WBC International Featherweight title.
