Saina engaged her opponent in long rallies and forced her to commit errors to move to 7-7 before taking the lead.

The World Championship silver medallist didn't get her shots right as a lot of her half smashes went into the net or outside as Saina went into the break leading 11-7.

Saina ruled the roost after the break and moved to 14-8. The Indian varied the pace of the game and judged her rival well to gain points, reaching 20-9.
