Hello
Treesa and Gayatri suffered their third loss to Hsieh and Hung this year.
The win against Antonsen is the 22-year-old Rajawat's first-ever victory over a top-10 player.
Treesa and Gayatri lost a close opening game before losing steam in the second.
The Indians, ranked No. 30 in the world, registered a superb comeback victory.
World No. 10 H S Prannoy, seeded eighth, lost to Kenta Nishimoto.
There were four Indians in men's singles qualification round but none could make it to the main draw.
Playing his eighth tournament this season, Srikanth finally got some momentum as he made his first last-four appearance in 16 months.
Anmol Kharb outplayed Pornpicha Choeikeewong 21-14, 21-9 in the decider.
World No. 23 pair of Treesa Jolly and Gayatri Gopichand, world No. 53 Ashmita Chaliha and the 17-year-old Anmol Kharb registered stunning wins in the first doubles and second and deciding singles to take India through to the summit clash.
The 24-year-old Ashmita remained the only Indian in the fray after Mithun Manjunath lost his men's singles quarterfinals while the women's doubles pairs of Treesa Jolly and Gayatri Gopichand also exited from the Super 300 tournament in the last-eight stage.
