Rio Games silver-winner Sindhu defeated world No.18 and 2017 BWF World Junior Championship bronze-medallist Cai Yanyan of China 21-13 17-21 21-14 to set up a meeting with former world champion Okuhara.
This is Sindhu’s second semifinal of the season, following a last-four finish at the India Open last month.
Sindhu broke off at 5-5 in the opening game to earn the bragging rights but her Chinese rival came back strongly in the second game, opening up a lead of 11-6 at the break.
The Indian fought back superbly to narrow the lead to 15-16 before Cai marched ahead to take the match to the decider.
In the third game, Sindhu once again found her bearings and surged to a lead of 11-5 before the interval. The Indian continued to move ahead and closed out the match comfortably in the end.
Kidambi Srikanth, taking on top seed Kento Momota in the men’s singles quarterfinals in the evening match, got off to a worst start possible, losing six straight points. He then came up with a fightback to get on even terms with Momota though.
The Japanese shuttler then tightened the noose, racing to an 18-12 lead. In what a see-saw first game, Srikanth managed to claw his way back yet again, but Momota squeezed through the first game 21-18.
The second game saw some stunning rallies and Srikanth taking the early lead. Parity was restored at 6-6 and Momota took the lead in this game too thereafter. However, Srikanth was not in any mood to concede an inch and finally nosed ahead himself at 16-15 and took the game 21-19 to force a decider.
Momota raced to a 5-0 lead in the third game but yet again Srikanth managed to claw his way back. A leaping defence stroke landed just inside the court to give the Indian a 7-6 lead, forcing Momota to sit down on his haunches and stare at the inner line in disbelief.
The Japanese started approaching the net a lot more as the decider wore on, leading 11-7 at the last interval. After the interval, Srikanth suffered a capitulation, giving away eight straight points before eventually losing 9-21.
