Chinese paddlers Xu Xin and Sun Yingsha reached the final of men's and women's singles respectively at the T2 Diamond Singapore here on Sunday.

Top-seeded Xu took control of the match against Japanese teenager Tomokazu Harimoto and moved 11-7, 11-7, 9-11, 11-6 ahead after four games. As the "FAST5" came into play, Xu went on to pocket the win in the fifth game 5-4 and secure a final spot.

But teammate Lin Gaoyuan failed to join him in the final later on Sunday. Lin was swept by Lin Yun-Ju of Chinese Taipei 11-6, 11-10, 11-8, 11-8.

In women's semifinals, it took Sun full games to overcome fellow Chinese Wang Manyu 4-11, 7-11, 11-4, 10-11, 5-2, 5-1, 5-1.

Sun will next face Japan's Mima Ito, who saw off Jeon Ji-hee of South Korea after five games.
