Hong Kong's flagship pairing of John Hui and Melvin Tong cruised into the semi-finals of men's doubles at the AIA Asian Championships at Victoria Park yesterday. But last month's All-China National Games bronze medallists will have their work cut out as they seek a place in Sunday's final. Hui and Tong hardly raised a sweat as they thrashed Macanese pair Kuan Chu-seak and Lei Hou-in 6-0, 6-1, but they don't expect another easy romp as the Hong Kong pair will have their hands full, taking on classy Japanese combination Hiroki Kondo and Takahiro Terachi today. Kondo and Terachi, the second seeds, displayed fighting qualities to down Taiwan's Cheng Wei-jen and Wang Yeu-tzuoo 6-1, 6-7 (4-7), 6-1. Hui was pleased that they had reached the semi-finals, saying with Tong, he had gained in confidence since winning bronze at the All-China Games in Guangzhou last month. 'We are both playing well and we are confident of reaching the final. We're not going to think about our opponents for now and we are going to take each match as it comes,' said Hui. 'We have been playing together for 14 years since our junior years and we have been playing consistently well together. We had a tough first match [against Peter Handoyo and Suwandi of Indonesia] and that pretty well set us up for our match today.' Hui and Tong were the sole survivors for Hong Kong in the tournament after Hui and SAR women's champion Tong Ka-po bowed out of the mixed doubles, losing to Zu Benqiang and Li Na of China, 7-6 (9-7), 7-5 in the quarter-finals. Meanwhile, Thailand's Paradorn Srichaphan reached the semi-finals of men's singles after defeating South Korea's Yoon Yong-il 7-5, 6-2. Srichaphan, the number two seed, will take on Japan's Takao Suzuki, who beat Taiwan's Wang Yeu-tzuoo 7-5, 6-2. 'He's [Suzuki] is a tough player and he beat me in Davis Cup in Japan [February] when Japan won 5-0. But I'm hoping for the best,' said 22-year-old Srichaphan. There were three upsets in women's singles. Taiwan's Hsieh Su-wei, the fifth seed, beat second-seeded Saori Obata of Japan 6-3, 7-5 and seventh-seeded Jeon Mi-ra of South Korea came from behind to beat fourth seed Rika Fujiwara of Japan 5-7, 6-2, 6-3. Third-seeded Cho Yoon-jeong of South Korea thrashed eighth-seeded Haruka Inoue of Japan 6-3, 6-1, while top-seeded Wynne Prakusya of Indonesia dispatched China's Liu Nan-nan 6-3, 6-1.
