It’s obvious that the fight will not last all 12 rounds. So who will win? We don’t know how Anthony Joshua is boxing against the left-handed opponents. But I see him to win on the distance. The one reason is that he’s fighting at home. And I doubt that somebody in the USA believes that Martin can defend his title, because he is settled to fight on away ground. Martin had the second training period in a short period of time. His previous fight was short because of the injury of his opponent, Glazkov.
So Martin can’t be seen as a favourite. I think it is just a possibility to make some money in the UK for him. Joshua is a puncher, he got all his wins by the KO. I back Joshua to win in the 4-6 rounds.
