India's Kidambi Srikanth made a winning start but PV Sindhu and HS Prannoy were ousted from the Singapore Open Super 750 tournament after suffering contrasting losses in the opening round in Singapore on Tuesday. Srikanth, a 2021 world championships silver medallist, beat Thailand's Kantaphon Wangcharoen 21-15 21-19 in the opening round of men's singles competition. He will face Chinese Taipei's Chia Hao Lee, who beat Japan's Kenta Nishimoto in his opening match after being promoted to the main draw from the reserves.

Up against world number 1 Akane Yamaguchi of Japan, defending champion Sindhu fought hard before going down 21-18 19-21 17-21 in a little over an hour. The two last faced off in Thailand last year.

Prannoy, who came into the tournament after claiming his maiden BWF title at Malaysia Masters, couldn't match the young Kodai Naraoka, losing 15-21 19-21 to the third seeded Japanese in 56 minutes.
