Anthony Joshua is world champion

Quote MessageIt was only 94 days ago that Charles Martin won the title. His reign is now the second shortest in world title history. There's no chance Anthony Joshua's reign will be anywhere near that short.
How many more questions can Anthony Joshua answer?
He's told us he wants to unify the division and who can argue with him now? He conquered an unbeaten man, swatting him out of the way like some pesky fly.
He dealt with a southpaw stance like he was solving a two-piece jigsaw.
He dealt with nerves like a man born without emotion.
Any more for any more?

Andrew Priestley: 16 fights. 16 wins. 16 knockouts. Anthony Joshua is an animal. He will become a multiple world champion and remain one for years.
Bisa Amoo-Gottfried: Disappointing by Martin. Expected more, but when AJ hits you, you stay HIT.
When the game is up, the game is up.
Martin v Joshua
The end came one minute and 32 seconds into round two.
Ironically, for an AJ fight, that's quite long.
Charles Martin raises the hand of his conqueror. For me, Martin is relieved.
Martin v Joshua
Ladies and gents, the IBF world heavyweight champion. Good luck taking that title away from him.

Martin v Joshua
The replays are conclusive, Anthony Joshua showed slick footwork and balance to slip and throw in one movement, pure class.
Charles Martin was angered by the official, he thought he'd beaten the count. Had he done so I'd have bet the bounty I didn't win on the Grand National today that he'd have been decked for a third time.
Martin v Joshua
Great Britain: you have a new superstar. Anthony Joshua is up on the ropes with his arms aloft, he can't believe how easy this was.
Charles Martin got tagged heavy and his balance wasn't there, down he went, it was flush on the jaw. He took his breather, came back for more and walked onto an identical shot.
The count came, he didn't beat it and Anthony Joshua is the IBF heavyweight champion of the world.
Martin v Joshua
Charles Martin is DOWN, a right hand has floored him... this is going to be over...
Up he gets, he looks worried and so he should be, they engage, ANOTHER RIGHT... down again...
Martin v Joshua
One right hand landed crisply in particular in that opening round. One thing you have to say about Anthony Joshua is so far in his career he has been accurate to go with the power.
Out they come again. Charles Martin just pawing with the right hand jab. BANG, he gets a right hand to his face, through the guard. Those blue gloves of Anthony Joshua are flying nicely...

Quote MessageIt was a very calculated first round from Joshua. He did well with his jab and went on to land more right hands.
Martin v Joshua
Charles Martin is a southpaw, he leads with his right hand, Joshua with his left so these men are trying to find foot space... A NICE RIGHT FROM JOSHUA. What a confidence builder. He goes again, right hand lands, superb stuff, where are the nerves?
Again their feet are close, that's what happens when orthodox meets southpaw. Left hook, right hand from AJ, both accurate as Martin nears the ropes. This round is going to the Olympic champion by some margin.
Martin v Joshua
Out they come. Anthony Joshua with the world's most chiseled back comes forward and throws a right hand but gets nothing. His white shorts glisten, Charles Martin is in gold trunks and he gets caught in the stomach by a downward right from the challenger...

Micah Hall: AJ in 2. The best heavyweight we have produced since Lennox Lewis and, considering how good Haye is, that's a compliment.
