Andy Roddick officially retired from professional tennis following his four set defeat to Juan Martin Del Potro. Roddick is the last American male to win the U.S. Open which he did in 2003, also finishing that season as the year-end World #1 player. He won the Davis Cup in Portland, Oregon in 2007, opening the tie with a win over Tursunov. Roddick also competed in three Wimbledon finals, finished in the top 10 for eight years, and surpassed over 600 career ATP singles wins this year, a rare milestone.Respected for his diligent work ethic and extroardinary fighting spirit by tennis fans all over the world, Roddick will be missed by tennis and American sport in general.His conqueror today, the classy Argentine Del Potro showed remarkable sportsmanship and a sense of honor by deferring his post match victory bow to the teary-eyed Roddick, who then made a speech thanking his parents, telling the Ashe Stadium and worldwide audience, "I love you," while also making a special tribute to his deceased long-time agent Ken Myerson.Farewell, to Andy Roddick, a great champion and a future Hall of Famer.(Photo by Brett Connors.)
