Australian Hannah Green closed the third round with a one-stroke lead at the Women's PGA Championship.

Green carded a two-under-par 70 on Saturday to remain the woman to beat at Hazeltine National Golf Club.

The 22-year-old teed off with a three-shot advantage, but Green's lead was cut to one after bogeying the last in Chaska, Minnesota.

Green – bidding to become the first Australian to win the major LPGA Tour tournament since Karrie Webb in 2001 – is nine under overall, ahead of Ariya Jutanugarn (68).

Lizette Salas (68) and Nelly Korda (69) are tied for third and four strokes off the pace.

Defending champion Park Sung-hyun, meanwhile, posted a 71 to be five shots behind Green heading into the final round.
