At the press conference in Cincinnati Steve Johnson had a pretty interesting opinion on Juan Martin Del Potro's wild card at the US Open. The Argentinian player could not use his protected ranking and so the organizers allowed him to play in the main draw.
He will be unseeded and may face a top player like it happened at the Olympics (Novak Djokovic knows something about it...). Johnson thinks it is not a good move for the organizers to give a wild card to Del Potro.
If he beats a top American at the first round level, 'it may make a lot of American fans upset', Johnson said. Changing topic, Steve spoke about the toughness of tennis, which is the hardest sport for him: ''I'm going to be biased because i'm a tennis player, and I don't want this to come out the wrong way.
But in my mind, tennis is the hardest sport. You look at every Olympic final across all the sports. You had Murray and Delpo out there for four hours by themselves; for four hours one-on-one trying to solve big problems - how to win a gold medal.
A lot of other sports aren't as long and you had a team or coaches. Take nothing away - I liked watching Bolt win the 100 last night, but I think tennis is one of the hardest sports because you're on an island 24/7.
You have nobody out there with you. Take nothing away from every other sport.' ALSO READ: Conchita Martinez: 'Nishikori was in the toilet for 12 mins because he had a shower' .
