Stacy Lewis held on to lead Amy Yang by one stroke at the LPGA Thailand despite a dismal third-round 73 on Saturday in Chonburi, Thailand.
Leading overnight by three shots after a second-round 64, Lewis had three straight bogeys in the front nine before the American fired a five-foot eagle on the 15th hole to regain the lead from South Korea's Yang.
Third-ranked Lewis had five bogeys — including at the 18th — and two birdies at the Siam Country Club Pattaya Old Course for a three-day total of 13-under 203.
Sandra Gal of Germany shot 68 for third place, a further stroke behind Yang.
“It was a bit all over the place today,” Lewis said. “Hit some good shots, hit some shots too far.” Yang bogeyed Nos. 12 and 14 before back-to-back birdies on the 17th and 18th holes saw her finish with a 71.
Wallie Coetsee takes a two-shot lead into the final round of the Joburg Open after a 2-under 70 in Johannesburg, South Africa.
Chasing a first European Tour title, Coetsee extended his overnight lead by a shot with five birdies and two bogeys to go 14 under par at Royal Johannesburg and Kensington.
There are four players tied for second behind him, with fellow South Africans Tjaart van der Walt and Jacques Blaauw, and Englishmen David Howell and Steve Webster 12 under.
