China's seemingly never-ending pool of talent was on show again at the Malaysian Open in Johor Bahru and it was too much for Hong Kong's women's doubles pairing of Lin Ling and Zhang Rui. Cao Zhen, a 16-year-old who represents the army team Bayi, may be the lowest rated of the ranked Chinese players at 336 in the world, but she was still good enough to claim an impressive sweep of the titles, combining with Peng Yulang to beat Lin and Zhang 7-11, 12-10, 7-11, 11-9, 8-11, 11-6, 6-11 in the doubles, before moving to the opposite end of the table to overcome Peng in the singles. Lin and Zhang had beaten two Singaporean pairs, Jin Jung Hong and Li Jia Wei and Tan Paey Fern and Zhang Xueling to reach a Pro Tour final for the second time this year. Although the Hong Kong duo won the Brazilian Open in June, the SAR's head coach, Hui Jun, had little doubt that getting so far in Malaysia was more impressive. 'It's their third time in an Open this year and this was their best performance,' he said. 'The combination of play was a little better and their short game was also better than before. It's good enough to reach the final. We're happy.' Cao won a second gruelling final against Peng, who is ranked 50th in the world and represents Shandong, 11-6, 11-7, 5-11, 11-8, 3-11, 7-11, 11-8. 'It was close because we know each other so well from the practice hall,' said the shy teenager. 'However, at the decisive points I was the lucky one.' In the men's singles, Guangdong's Liu Guozheng ended a two-year drought on the Pro Tour, beating another up-and-coming youngster Hao Shuai. The 23-year-old from Shantao overcame the 20-year-old Tianjin native 6-11, 11-7, 11-7, 9-11, 11-5, 11-3 and admitted afterwards that the three years between them had been decisive. 'Yes, I think the experience made the difference. Hao and I play in the same club, and when we play, practice or competition, it is always very close,' said Liu. Liu also took two titles, joining Kong Linghui to defeat Chen Weixing, a Mongolian flying the Austrian flag, and Koji Matsushita of Japan 11-6, 11-5, 11-3, 2-11, 11-2.
