ANTHONY Clark and Nathan Robertson have been beaten in the second round of the Indonesian Open.
The English champion, who won the recent Singapore Open, went down 21-16, 24-22 in a close-fought 39 minute encounter with Joko Riyadi and Luluk Hadiyanto.
The defeat came on the day they learned their win over the Olympic and world champions last week had lifted them into the top ten of the world rankings.
England's Robert Blair and Scotland's Imogen Bankier reached the quarter-finals of the mixed doubles with a battling display against eight seeds Sudket Prapakamol and Saralee Thoungthongkam.
Blair and Bankier won 21-19, 11-21, 21-11 in 53 minutes and now face Olympic champions and second seeds Lee Yong Dae and Lee Hyo Jung of Korea.
Bankier had high hopes of a second quarter-final place but she and Donna Kellogg went down to sixth seeds Zhang Yawen and Zhao Tingting of China 21-11, 21-10.
Elsewhere, Robertson and Jenny Wallwork failed to reach the mixed doubles quarters, losing 21-15, 21-16 to Han Sang Hoon and Jang Ye Na.
In the new world rankings Rajiv Ouseph rises to a career best number 26 while Susan Hughes is the top ranked British woman at world number 29.
