Rarely is India's star shuttler PV Sindhu seen in an agitated state on and off the court. But yesterday, she was livid because some poor refereeing almost saw her make, what would have been an embarrassing first round exit in the women's singles event here. Sindhu was stretched to three games before beating Vietnam's Vu Thi Trang 21-10, 12-21, 23-21.

The No. 3 seed struggled to get a measure of the court more often than not, hitting the shuttle wide despite there being no pressure from World No. 52 Vu early on in the match. Later, her errors came back to haunt her when the referees called a couple of very close calls long, leaving Sindhu livid. "That was on the line," she kept telling the chair umpire even as she turned to chief coach Pullela Gopichand, who simply put his finger to his lip asking her to keep quiet and continue playing.
