 The third Grand Slam tennis tournament of the year gets underway tomorrow in England as defending Wimbledon champions Marketa von Rousseva and Carlos Alcaraz return to the grass court. Past champion Novak Djokovic says he is ready to compete. Djokovic had surgery less than a month ago to repair a torn meniscus in his right knee. He was injured in the French Open June 3rd. His first round match is scheduled for Tuesday.
