It has been almost three years since Martina Hingis last played a professional tennis match and yet at the age of 31, she still remains a dominant presence in the world of tennis. The ultra competitive Hingis spends her summer days playing on the World Tennis Tour for the New York Sportimes. The 5x Grand Slam winner plays both singles and doubles for the squad and even had the chance to be paired with tennis legend John Mcenroe in mixed doubles. I caught up with Hingis following a match in late July against the Philadelphia Freedoms.
