In the biggest moment of his pro career thus far Anthony Joshua was composed, clinical and concussive as two lead rights led to two knockdowns, the final of which resulted in a 10-count KO. Joshua landed 57% of his power shots to Charles Martin's 15% in a tension-filled, low output but highly satisfying spectacle.

For the record Joshua led 16-3 overall, 4-1 jabs and 12-2 power and 35%-5% overall and 16%-2% jabs and closed the curtain on Martin's 84-day reign, the second shortest heavyweight title tenure on record behind Tony Tucker's 63-day IBF title run in 1987.

Anthony Joshua MBE landed the IBF World Heavyweight title with a brutal second round KO win over Charles Martin at The O2, live on Sky Sports Box Office.

In front of a sold-out crowd at fever pitch in Greenwich, Joshua began with his trademark blistering speed and power in the opening round, rocking the unbeaten champion with solid shots.

The Olympic hero then exploded a counter right hand flush on the chin of Martin to seat the American. Martin gingerly rose to his feet inside ten seconds but Joshua repeated the trick moments later, and this time Martin failed to beat the count and after 92 seconds of the second round, Joshua was crowned IBF World Heavyweight champion.

“It is only a quarter of the way there,” said Joshua. “I am not going to get too carried away because there is a lot of work to be done. I have to keep on improving because I have people like Haye calling me out, Tyson Fury calling me out, all of them.

“I need to improve if I am going to maintain and keep pushing at a higher level. Every fight the atmosphere gets better, and better and better. The people here are coming out to support myself and all of the other British fighters on the undercard.
