Top Indian shuttlers Kidambi Srikanth and HS Prannoy were knocked out after suffering shock defeats in the second round of the men's singles competition here yesterday.

After Srikanth lost 21-23, 19-21 to Wong Wing Ki Vincent of Hong Kong in a 43-minute duel, Prannoy too followed suit going down 12-21, 21-15, 15-21 to Thailand's Kantaphon Wangcharoen in a 65-minute contest, much to the dismay of Indian fans.
