Sharath, three-time Commonwealth Games gold medallist, and Amalraj lost 111-8, 7-11, 9-11, 5-11 in 33 minutes to the Singaporean pair at the Scotstoun Sports Campus. It was the first medal for India from the sport in the 2014 Games.
The Indians started off well by winning the first game but performed badly in the second as Singapore raced away to a 11-7 win in just six minutes. The third game turned out to be a close affair that India lost 9-11. Singapore proved their supremacy in the fourth game winning it 5-11 with ease.
Interestingly, both Sharath and Gao had faced each other in the men's doubles 2010 final, which the Indian had won with Subhajit Saha in Delhi, with different partners.
