SINGAPORE: Local shuttlers had a mixed start on the first day of the main round of the Li-Ning Singapore Open 2011 badminton championship on Wednesday. Defending women's doubles champions Yao Lei and Shinta Mulia Sari moved into the last 16, but only after a tricky three-set win over England's Mariana Agathangelou and Heather Olver at the Singapore Indoor Stadium. Yao Lei and Shinta, who became the first Singaporeans in 20 years to win a title at the tournament, made a poor start, losing the opening set 21-19, before recovering to take the second set 21-8 to force a rubber, which they won 21-16.

Joining them in action on Thursday will be team-mates Chen Jiayuan and Xing Aiying, who beat England's Jenny Wallwork and Gabrielle White 21-16, 21-9 to reach the last 16. The pair will face fourth seeds Shizuka Matsuo and Mami Naito of Japan. But Vanessa Neo and Thng Ting Ting are out, after going down 2-1 to Denmark's Line Damkjaer Kruse and Marie Roepke. Singapore's other pair, Liang Xiaoyu and Tan Wei Han, were also knocked out by Australia's Leanne Choo and Renuga Veeran 2-1.
In the women's singles, Singapore's Gu Juan reached the last 16 after edging out Japan's Ayane Kurihara 2-1 (14-21, 21-19, 21-13). She will face either Japan's Ai Goto or seventh-seed Porntip Buranaprasertsuk of Thailand on Thursday. However, Singapore's Fu Mingtian and Chen were first-round casualties. Fu put up a spirited display before bowing out to China's world No 1 Wang Shixian 2-0 (21-10, 21-15), while Chen fell to Thailand's Inthanon Ratchanok by the same scoreline.
