US Women's Open: Amy Yang maintains three-shot lead

Should Yang maintain her lead, victory would be her first after four top-10 finishes in the last five years

South Korea's Amy Yang shot a one-under-par third-round score of 69 to maintain a three-shot lead going in to the final day of the US Women's Open.

Last year's American runner-up Stacy Lewis matched Yang's score to remain five under par in second.

Yang's compatriot In Gee Chun trails by four shots in third, with Japan's Shiho Oyama five behind in fourth.

Dame Laura Davies remains two over par in joint 28th, while fellow Briton Charley Hull is four over in 37th.

Defending champion Michelle Wie of the United States is one of four players tied on two under par in fifth place.

Should Yang maintain her lead at the end of Sunday's final round in Pennsylvania, victory would be her first at the US Open after four top-10 finishes in the last five years.
