BIRMINGHAM: An error-prone PV Sindhu suffered a straight-game defeat to her nemesis An Se Young of Korea in the women’s singles second round at the All England badminton Championships here on Thursday.

Sindhu, a double Olympic medallist, seemed to be in good touch as she fought hard against the world No. 1 Korean but failed to curb her mistakes as she slipped to a 19-21, 11-21 loss in their 42-minute clash.

It was the Indian’s seventh successive loss to the indomitable An Se Young, who had become the first Korean woman singles player to win the World Championships last year.

The Indian tried to attack but her 22-year-old opponent looked in a different league as she varied the pace of the rallies and used her repertoire of strokes well to come up trumps. For Sindhu, things went downhill after the break in the second game as errors kept piling up.
