World No. 8 Saina dug deep into her vast experience as she recovered from a game deficit to beat Thailand's Porntip Buranaprasertsuk 19-21 21-14 21-14 in a 58-minute clash at the quarterfinals stage of the USD 550,000 event. Saina had beaten Porntip seven times in their last eight meetings.
The Olympic bronze medallist Indian will next meet Tai Tzu Ying tomorrow. Saina has a 5-8 record against the Chinese Taipei shuttler, who has beaten the Indian in their last five meetings, including in last month's All England Championship.
With both the matches happening on adjacent courts, Saina and Sindhu both faced defeats in the opening game. Saina managed a comeback, but 20-year-old Sindhu was out of sorts as she was outplayed by her opponent.
Saina trailed 3-6 early on and even though she caught up after the break at 14-14, Porntip managed to get the better of the Indian in the opening game.
