Rajiv Ouseph's bold bid at the Li-Ning Singapore Open came to an end in the quarter-finals of the men's singles today when he fell to Indonesia's Tommy Sugiarto. The Commonwealth silver medallist, who yesterday stunned fourth seed Kenichi Tago, lost a close contest with Indonesian Sugiarto 21-19 21-18 after a 42-minute duel.

Ouseph recovered from 9-7 down to lead 10-9 in a tight first game before Sugiarto edged away to take the opener on his fifth game point. Ouseph trailed 16-10 in the second but fought back to draw level at 18-18 only for Sugiarto to take the next three points and with it the match.

Chris Adcock and Gabby White also saw their challenge come to an end when they were outplayed 21- 21-7 by third seeds Tontowi Ahmad and Liliyana Natsir of Indonesia 21-14 21-7 in 28 minutes in a contest where they were never ahead in either game.

Despite their defeat today, Adcock and White have climbed to No.18 in the world rankings since the start of the year. They will now step up their preparations for the world championships in Guangzhou from August 4-11 as Adcock aims to add to the silver medal he won in London in 2011.

Germany's Marc Zwiebler had to retire against Tien Minh Nguyen from Vietnam. Zwiebler, the current European Champion and world number 14, lost the opening game 21-23 and suffered an injury when the score was 8-11.
