Indian shuttler PV Sindhu won her second successive group stage match to qualify for the semi-finals but men's singles star Kidambi Srikanth lost for the second time in succession to be out of the race for the last four stage of the World Superseries Finals here on Thursday.
Sindhu crushed Japanese Sayaka Sato 21-13, 21-12 in 36 minutes to secure her second straight victory, eliminating Sayaka at the Hamadan Sports Complex.
The Indian joined Japanese Akane Yamaguchi to advance to the semi-finals from Group A.
