China's back-to-back world champions Zheng Siwei and Huang Yaqiong won their-first round clash, as mixed doubles action opened the Badminton World Federation (BWF) Indonesia Masters today.
The top seeds knocked out home pairing Hafiz Faizal and Gloria Emanuelle Widjaja, 21-14, 21-13.
Only mixed doubles games were played in the main draw at Jakarta's Istora Gelora Bung Karno today, with qualification taking place in the other events.
Asian Games champions Zheng and Huang were joined in round two by second-seeded compatriots Wang Yilü and Huang Dongping.
The reigning Asian Championship winners saw off another Indonesian duo, sweeping aside Ricky Karanda Suwardi and Pia Zebadiah Bernadeth 21-9, 21-15.
Another pairing to advance were fourth seeds Dechapol Puavaranukroh and Sapsiree Taerattanachai of Thailand, knocking out China's He Jiting and Du Ye 21-12, 21-12.
England's husband-and-wife team Chris and Gabrielle Adcock recovered from match point down to defeat Takuro Hoki and Wakana Nagahara of Japan.
The Commonwealth Games gold medallists came through 19-21, 21-16, 22-20.
The event is the second of the BWF World Tour season after the Malaysia Masters, which concluded in Kuala Lumpur on Sunday (January 12).
It is rated as a Super 500 tournament, with the men's and women's singles and men's and women's doubles beginning tomorrow.
Competition has been overshadowed after Japan's world number one player Kento Momota was involved in a traffic accident after winning the men's event in Malaysia, which killed his driver.
Momota suffered multiple laceration wounds to the face and a fractured nose, but had already withdrawn from competing in Indonesia.
He is a big Japanese hope for home gold at the Tokyo 2020 Olympics.
