June 30 (Reuters) - South Korean Ryu So-yeon hit a precise approach shot for a tap-in birdie at the final hole and a three-shot lead after the third round at the KPMG Women’s PGA Championship outside Chicago on Saturday.
Former world number one Ryu took a big step towards a third major title with a five-under-par 67 in scorching conditions at Kemper Lakes in Kildeer, Illinois.
She posted an 11-under 205 total while Canadian Brooke Henderson shot 70 to be alone in second place on eight-under with one round left.
South Korean Park Sung-hyun, who shared the halfway lead with Ryu and Henderson, shot 71 to slip four strokes behind.
