The 24-year-old Indian gradually began to take control of the proceedings. The Chinese battled hard but Saina managed to win the game 21-18.

The second game was a neck-and-neck contest till both the shuttlers reached the 12-point mark. Jinping rattled Saina by taking four straight points. The Indian took one point and also conceded one to trail 13-17.

Later, Saina staged a brilliant comeback to equalise 17-17 and sprung into rhythm to take the next four points quickly as Jinping added only one to remain at 18 points.
