World No. 1 Nelly Korda pulled within tantalizing reach of the gold medal in Olympic women's golf on Friday, while Aditi Ashok boosted India's hopes of an unlikely podium spot after the third round at Kasumigaseki Country Club.

The overnight leader by four strokes, American Korda carded a two-under 69 to lead by three from Ashok (68). Japan's Mone Inami sits five shots off the pace in a four-way tie for third.

"I've been actually really calm for the last three days, I haven't got really got nervous," Korda told reporters after saving par on the 18th with a splendid up-and-down.
