Americans Katie Futcher, Angela Stanford and South Korea's Jenny Shin all shot 1-under 71s on Saturday to stay tied for the lead after three rounds of the $1.4 million HSBC Women's Champions.
Futcher led almost the entire day, jumping ahead with a birdie on the second hole. But a bogey on 18 - her first of the tournament - allowed Stanford and Shin to regain a share of the lead at 9-under 207.
World No. 1 Yani Tseng climbed up the leaderboard with a 5-under 67 and was three strokes off the lead at Tanah Merah Country Club.
China's Shanshan Feng shot a 69 to be two shots behind the leaders while South Koreans Jiyai Shin and Na Yeon Choi were tied with Tseng three shots back.
