Chris Adcock and Imogen Bankier's bid to reach their second Super Series quarter-final in successive weeks ended in frustration today at the Yonex Japan Open in Tokyo.

The world silver medallists went down 21-18 21-15 after another battling display against third seeds Sudket Prapakamol and Saralee Thoungthongkam.

The Anglo-Scottish pair were ahead in both games before their more experienced Thai opponents hit back.  In the first Adcock and Bankier led
12-8 before Sudket and Saralee turned it round to build on a 15-13 advantage and take the opener on their first game point.

But Adcock and Bankier started the second game strongly and raced into a
5-0 lead before the Thai pair drew level at 10-10 in the middle of a six-point burst which swept them 14-10 ahead.

Adcock and Bankier weren't about to give up and were still in contention at 15-14 before Prapakamol and Thoungthongkam put in a final surge to complete their third win in a year against their younger rivals.

Even so, last week's efforts in China saw Adcock and Bankier climb up a place in the BWF world rankings to No. 15, just three places behind team-mates Nathan Robertson and Jenny Wallwork, who dropped a place to No. 12. Scotland's Robert Blair and England's Gabby White, who were also quarter-finalists in China, moved up three places to No. 21.

The focus will now switch to the next two European events on the OSIM BWF World Super Series circuit with the Denmark Open in Odense from October 18-23 and the French Open in Paris from October 25-30.

On the rankings front Elizabeth Cann went up four places to No. 38 in the women's singles following her semi-final effort at last week's Yonex Belgian International.

That leaves her just eight places behind her great Scottish rival, Susan Egelstaff, who remained at No. 30 despite reaching the Guatemala International semi-finals.

In the men's singles Rajiv Ouseph moved up one place to No. 34 in the world while Adcock and Andy Ellis went up one to No.19 in the men's doubles rankings after their quarter-final effort in China last week. Marcus Ellis and Peter Mills are No. 34 and Anthony Clark and Chris Langridge No. 35.

In women's doubles Mariana Agathangelou and Heather Olver's reward for reaching the final in Belgium is a rise to No. 22 with Wallwork and White sliiping two places to No. 35.
