World No1 amateur Lydia Ko has saved her best for last at the LPGA Championship in New York.
The 16-year-old from the Gulf Harbour Country Club shot a three-under-par 69 in the final round at the demanding Locust Hill Country Club in Pittsford to climb 20 places from tied 37th to a share of 17th place.
The final day proved to be a battle of endurance with the world's best golfers completing 36 holes to decide the championship after heavy rain forced the suspension of play of round one.
Ko's equalled her best finish in a major championship after she finished tied for 17th at the British Open at Hoylake last year where the field also completed 36 holes on the final day.
The New Zealand Women's Open champion finished six shots back from winner South Korean Inbee Park and Scottish pro Catriona Matthew who finished tied on a five-under-par four round total of 283.
