He beat the count and fought on, although appeared to be saved by the bell in the opening round as Quigg had him pinned to the ropes.
The bell just served to delay the inevitable as the champion came out looking for the stoppage in the second round, and landed a big left hand that sent Munyai to the canvas once more. Munyai again rose to his feet but with much more time left in the round Quigg forced the pace and landed more hurtful shots forcing referee Howard Foster to step in and halt the action.
"He took the fight at late notice but I demolished him," Quigg told Sky Sports. "I wanted to make a statement and I said you were going see the best of Scott Quigg," he added. "No-one has ever done that to Munyai."
Josh Warrington (17-0, 2kos) successfully defended his Commonwealth title against experienced campaigner Rendall Munroe (28-5-1, 11kos). The fight began evenly, both fighters trying to work the body but as it went on Warringtons speed became the defining factor. Munroe who was coming off the back of a stoppage defeat to Welshman Lee Selby, was forced to lunge with his punches, often throwing off balance and leaving himself open for any counter shots.
As the fight went on it became clear that Munroe was unable to keep up with the younger man, and his long time trainer Jason Shinfield pulled his fighter out. Warrington who didn’t have a stoppage in his first 15 fights, now has two in his last two fights.
Munroe was tearful at the end of the fight, and it appeared to all who watched that he had come to the end of a successful career. "I love the sport and the training, but there comes a time when the sharpness isn't there," a tearful Munroe told Sky Sports.
"At the end of the day I went to Japan, fought the best in the world, I never reached my goal but I love the sport and my fans and a big thank you to them."
Callum Smith (10-0, 8kos) returned to action after six months out of the ring with an impressive third round stoppage win over Frenchman Francios Bastient (43-11-1, 18kos). The fight was a warm up fight for Smith who fights Tobias Webb in Cardiff next month, and while Bastient was a game challenger, he was always overmatched. Smith controlled the fight well with his jab and worked the body superbly, and it was a body shot that brought a stop to the action.
As Bastient moved forward, Smith landed an uppercut to the chest which crumbled his opponent, he rose to his feet but his corner brought an end to the stoppage shortly after.
Tyrone Nurse (28-1, 5kos) claimed the English Light Welterweight title with a unanimous points victory over Tyler Goodjohn (10-3, 4kos). Goodjohn gave it his best effort and tried to force the pace, but landed very little clean for the duration of the action. Nurse was able to role the punches or evade them completely while landed several shots of his own in reply. By the end of the fight Goodjohn was bloodied and bruised but can hold his head high, he showed fantastic effort against a slick boxer and is young enough to come again.
A great night of action in Manchester, the talk is now for Scott Quigg to chase Leo Santa Cruz or Kiko Martinez. That would be a big step up for the man from Bury and one that I would love to see, I believe he has what it takes to beat Martinez and run Santa Cruz very close. The other question for the night is what next for John Murray, he always takes a lot of punishment but has the heart of a warrior and I am sure we’ll see him back in the right later this year.
