Second seed Cecil Mamiit and Indian star Leander Paes crashed out of the CMG Open at Victoria Park yesterday. American-Filippino Mamiit retired from his first-round battle with compatriot Michael Joyce after suffering a knee injury, while Paes, the world number-one doubles player, lost 7-5, 6-1 to Romanian Razvan Sabau. After losing the opening four games, Mamiit suddenly came to the net and offered to shake hands with Joyce and limped off the centre court. Mamiit looked in pain as early as the third game. During his serve, he deliberately hit the ball to concede that game. A dejected Mamiit was unavailable for comment, but tournament director Jeff Mann said it was a recurring tendon injury that he had picked up in the San Jose tournament last February. As for Joyce, he admitted he was disappointed that Mamiit had to retire. 'It took me by surprise when he decided to retire,' he said. 'I practised with him yesterday and he was fine. I would have liked the match to continue as I was confident of winning. The fans must have felt disappointed, too. But I realise how he must be feeling, because I've had to retire a few times during my career. You have to accept it as part of the game.' Joyce is making his fourth appearance in Hong Kong, having played twice in the Salem Open and the Marlboro Championship. Now he is after the title. 'Nowadays in men's tennis, seedings don't count for much,' he said. Joyce will meet the winner of the Martin Spottl-Emanuel Couto match in the second round. Hong Kong's Davis Cup player, Melvin Tong Man-chung, saw his dreams shattered when he was beaten 6-1, 6-0 by Sweden's Andreas Vinciguerra. The sixth seed booked a date with Japanese qualifier Yaoki Ishii in the second round. Top seed Andrew Ilie and former world number-one doubles player Todd Woodbridge, both Australians, play today.
