PV Sindhu survived a scare before making the semi-finals but Saina Nehwal was thoroughly outplayed in her straight-game quarter-final loss on a mixed day for India at the Singapore Open badminton tournament here yesterday.

Sindhu, in fact, emerged as the lone survivor after India's campaign in men's singles was over following the ouster of Kidambi Srikanth and Sameer Verma, and loss of mixed doubles Indian pair of Pranaav Jerry Chopra and N Sikki Reddy later in the day.
