England's Anthony Joshua had just knocked American Charles Martin silly in the second round Saturday in front of a sellout crowd at London's 02 Arena to win a world heavyweight title in just his 16th professional fight.
It was the kind of occasion that would set off a wild celebration for most boxers. But Joshua, although smiling ear to ear, hardly celebrated in the ring after knocking Martin down twice in the round with powerful right hands to the chin.
Martin (23-1-1, 21 KO) was counted out on the second knockdown and thus turned his title over to Joshua after having owned it for less than three months. He will go down as a footnote in boxing history as the heavyweight who had unquestionably the easiest road to a world title and who wound up with one of the least memorable reigns ever.
But for Joshua, it could be the beginning of big things as he is poised to become one of the faces of boxing in the post-Floyd Mayweather/Manny Pacquiao era.
Yet there was virtually no celebration from Joshua (16-0, 16 KOs), who added a world title to his 2012 super heavyweight Olympic gold medal.
"It is only a quarter of the way there," Joshua said. "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 [former titleholder David] Haye calling me out, [unified champion] 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."
It is not that Joshua was not happy with his victory. He was very happy with it. He just believes that he still has a lot to learn and that it is important to him to keep giving his supportive fans a reason to turn out to see him and to buy his fights on pay-per-view.
"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," he said. "I come to knock people out. I want to give value for money and I really do appreciate everybody because there were times when we were training in Finchley ABC when nobody cared and I have been grinding my way here. I appreciate the ongoing support time and time again."
Joshua said he was never awed by the moment and that he simply remained focused on what he had to do rather than get caught up in the enormous hype.
"Regarding all the hype, I stay tucked away in the gym," he said. "All the hype is good for everyone in boxing, not just myself. Keep on pushing this sport. They have been calling me out since last year, so it is nothing unusual. I will keep on grinding, keep on working hard, and once we step into this ring, trust me, I will be ready."
Matchroom Boxing promoter Eddie Hearn knows that in Joshua he possibly has a truly special fighter on his hands, one who is committed to doing the business in entertaining style in the ring and being a role model and ambassador for the sport outside it.
"This guy is the most humble sportsman you can meet," Hearn said. "He has just won the heavyweight championship of the world and it looks like he has just won a four-rounder. This is only the beginning. He has aspirations to unify all the belts, and he will."
Hearn said Joshua could be back for his first defense on July 9 at Wembley Stadium in London, although that is the date on tap for the rematch between Fury and Wladimir Klitschko, who are also going to fight in England.
Whenever Joshua fights next and whomever he faces, Hearn couldn't have been more effusive in his praise after the knockout of Martin.
"Britain should be very, very proud," Hearn said. "The sport has a chance with a role model who can transcend the sport that young people can look up to. Anthony Joshua won the Olympic [super] heavyweight championship, the British heavyweight championship and [Saturday] he won the world heavyweight championship. This man will go on to be a real great.
"This is going to be the biggest star in world boxing, if he is not already. He is so humble and down-to-earth, and he can beat them all. He is the real deal, and he will beat everybody."
