Kevin Mitchell (right) floored Ignacio Mendoza in the second round
Kevin Mitchell moved a step closer to a world title fight with Australian Michael Katsidis after defeating Ignacio Mendoza at Wembley on Saturday.
Mitchell, 25, is the WBO's number-one mandatory contender for the lightweight title and could face Katsidis if Juan Manuel Marquez relinquishes his belt.
Dagenham's Mitchell is now unbeaten in 31 fights following his second-round knockout of Colombian Mendoza.
Mitchell floored Mendoza with a fine right hook, left uppercut combination.
It was the 23rd time Mitchell had stopped a fight inside the scheduled distance although, up until the decisive moment, the bout had been relatively even.
The right hook over the top, landing flush on the chin, was followed by a left-hand uppercut to the throat of the Madrid-based 26-year-old, who failed to regain his feet one minute 24 seconds into the round.
"I wanted show that I can box but I've got power also and it worked," said Mitchell.
The first round I was too eager, I wanted to put on a show, apart from that it was alright
"His next fight will hopefully be against Katsidis and I want it here at Wembley," added promoter Frank Warren.
Big-hitting Katsidis is the WBO's interim champion and that fight would most likely take place in the summer.
If as expected Marquez is made to relinquish his title then that fight would be for the WBO belt. West Ham's Upton Park and the O2 Arena are also possible venues for the potential fight.
Meanwhile, Olympic gold medallist James DeGale maintained his 100% professional record with his six successive victory following an impressive second-round victory over Matthew Barr.
DeGale, 24, began confidently in front of his home crowd at Wembley, stinging Barr with a fierce right early in the first.
But it was the second round where the Londoner showed his class, flooring Barr with a chopping left before sending the 32-year-old to the canvas two more times to end the fight.
"The first round I was too eager, I wanted to put on a show, apart from that it was alright," said DeGale.
"I thrive on pressure and I absolutely loved it out there tonight."
Frankie Gavin also extended his perfect professional record to six victories with a six-round points win over Irishman Peter McDonagh in London.
Birmingham southpaw Gavin, 24, had stopped all five of his previous opponents and was looking to extend that run in north-west London.
However, he was forced to go the distance against 32-year-old Galway fighter McDonagh in an entertaining contest.
Elsewhere, Derek Chisora stopped Carl Baker in the second round of their British heavyweight title eliminator clash to set up a potential meeting with champion Danny Williams.
Chisora, 26, had been due to meet Williams on Saturday before the Brixton fighter pulled out because of illness.
"We are in the boxing game, certain fighters don't want to fight me, we'll see if that happened," said Chisora.
