Jakarta: World number two Akane Yamaguchi thrashed Olympic medalist PV Sindhu in straight sets 21-15, 21-16 to lift the Indonesia Open title, here, on Sunday.
Though it is Sindhu's fifth defeat against the Japanese shuttler, her poor run in the finals of the mega tournament is a major worry for the star shuttler.
Sindhu had come into the contest with a favourable 10-4 head-to-head record against the Japanese.
Nevertheless, it was season's best performance for the world number four Indian, who had reached the semifinals at Singapore and India Open earlier.
