Take one look at Argentina's Gustavo Fernandez and you can see he's an athlete - even sitting in his wheelchair.
He's been a fixture in elite Wheelchair tennis for several years now, and has recently climbed to number one overall.
The 23-year old, whose father and brother have played professional basketball in his native country, claims it's a three-part proposition to get to the top: physical, technical and mental skill and consistency. It's the mental part of the game that he has focused on most recently, and it played a part in Fernandez's opening win at the Dwight Davis Tennis Center.
Frank Cusumano tells his story.
