China"s Lin Xiyu carded a superb five-under-par 67 on Saturday to take a one-shot lead over Australia"s Hannah Green and South Korea"s Inbee Park heading into the final day of the HSBC Women"s World Championship in Singapore. Lin got off to a poor start with a bogey on the first hole and faltered again on the seventh, but seven birdies - including three in the last four holes - took her total to 14-under for the tournament at the Sentosa Golf Club. "I wasn"t really paying attention to the leaderboard because to me, the front nine was a little sketchy," Lin said. "I made two three-putts, weird mistakes and left birdie putts short. "So going into the back nine which I thought was the tougher nine, I didn"t really expect to play that well but I also knew there are still lots of opportunities, so just needed to stay really patient. The last couple holes were unreal." Former world number one Park, the overnight joint-leader, dropped one spot to be tied for second following a disappointing effort after the turn where had two bogeys before a double-bogey on the 16th for a round of 70. "I still have an opportunity. That"s what matters, and I"ll go out there tomorrow and try to go low," the 2015 and 2017 champion - who is in the race to make the South Korean team for the Olympics - said. She was tied with the steady Green, whose second consecutive round of 66 kept her in contention for only a third victory on the LPGA Tour. The leading trio were followed by Mexico"s Gaby Lopez in fourth and a group of three - Chun In-gee, Lydia Ko and Ryu So-yeon - sharing fifth. South Korea"s Park Hee-young, who shared top spot heading into the third round, slipped to tied-21st after her game went off the rails on the back nine for a round of 79. ANA Inspiration winner Patty Tavatanakit of Thailand was tied 11th with British Open champion Sophia Popov after a round of 68.
