SINGAPORE - Olympic mixed doubles champions Tontowi Ahmad and Liliyana Natsir of Indonesia were uncharacteristically booted out early at the OUE Singapore Open, suffering a loss in their opener at the Singapore Indoor Stadium on Tuesday evening.
They were swept past 21-14, 21-16 by Thailand's Dechapol Puavaranukroh and Sapsiree Taerattanachai in the first round of the Superseries event.
The Indonesian duo, who took gold at the Rio de Janeiro Olympics last year, are three-time champions here, having won in 2011, 2013 and 2014.
But with Liliyana struggling with a knee injury that has hampered her movement since the China Open last November, the pair struggled to keep up with their Thai opponents.
Tontowi also admitted that he could not get into the rhythm of the match. He said: "We didn't play well today and our communication wasn't great. By the time I got my momentum, it was already too late to catch up."
Added Liliyana: "I haven't been able to recover and I was reluctant to take certain shots today."
Team Singapore's Terry Hee and Tan Wei Han earned a place in the second round of the mixed doubles after they beat Indonesians Ronald Ronald and Melati Daeva Oktavianti 21-19, 22-20.
The world No.1 5s get a day of rest and will meet All England Open champions Lu Kai and Huang Yaqiong of China on Thursday.
In the women's singles, Yeo Jia Min will also get to play in the main draw after she got through the qualifiers. The world No. 2 junior beat Indonesia's Lyanna Alessandra Mainaky 21-19, 21-18, having also taken out Jesica Muljati of Indonesia 21-12, 21-18 earlier in the day.
Singapore's other shuttlers lost their matches on qualifying day.
