Shanshan Feng left it late on Saturday in the third round at the US Women's Open at Trump National Golf Club Bedminster, making a birdie on the final hole to maintain her lead.
The birdie on the par-five 18th ended a run of 23 consecutive pars for the Chinese star and saw her earn a one-stroke lead over a pack of chasing South Koreans.
Feng’s round of one-under 71 saw her complete 54-holes with a total of nine-under 207, one shot ahead of Amy Yang and 17-year old Choi Hye-jin, who both carded rounds of 70.
Yang and Choi had earlier drawn level with Feng, Yang sank a 20-foot at the 17th hole, while amateur Choi birdied the par-three 16th.
But Feng, who had missed a succession of birdie opportunities during her round, finally grabbed a long-awaited birdie after nailing an iron shot to three-feet at the par-five 18th.
South Korea’s Park Sung-hyun lies three shots behind after racking up six birdies on the back nine for a 67.
Compatriots So Yeon Ryu (71), Mirim Lee (67) and Lee Jeong-eun (73), were one shot further back at five-under par.
Former champion Cristie Kerr carded a 70 to finish at four under par along with Spain's Carlota Ciganda (72).
