His nickname is The Tower of Tandil and once again the former US Open champion has rising to the occasion in the city that never sleeps.
New York is like a home for Del Potro from what he did in 2009 seeing off Nadal and Federer on route to the title but what he is doing now might just be even more special.
Over the last few years he has had four surgeries on his left wrist missing years of tennis but has come back strong something many thought he’d never be able to do again.
Last year he was the star in Davis Cup and picked up an Olympic medal in Rio and this year he has got better and better and his run in New York seeing off Thiem and Federer over a period of 9 sets is what he is about doing the unthinkable something others can only dream of.
He is loved worldwide and you wouldn’t find anyone who dislikes him, his character is infectious and what makes him such a great champion is that he is humble, kind, respectful and he plays with a smile on his face.
A semi-final against Rafael Nadal is up next on Friday for the Argentine and it sets itself up to be a spectacular battle between two giants in what feels like a final but one will play either Kevin Anderson or Pablo Carreno Busta in Sunday’s final.
