Mi Jung Hur birdied the par-5 18th hole for a six-under-par 67 and a one-stroke lead over Brooke Henderson on Saturday in the Reignwood LPGA Classic.
Hur was five under on the back nine to reach 20-under 199 at Reignwood Pine Valley in the Asian Swing opener. The 26-year-old South Korean player, a two-time LPGA Tour winner, had a bogey-free round after shooting a tournament-record 63 on Friday for a share of the second-round lead with Henderson.
The fourth-ranked Henderson closed with a par for a 68, also avoiding a bogey. Planning to play all six weeks in Asia, the 19-year-old Canadian has two victories this year, winning the KPMG Women's PGA Championship in June for her first major and successfully defending her Cambia Portland Classic title in July.
China's Shanshan Feng, the bronze medallist at the Rio Olympics, was three strokes back along with South Koreans Mirim Lee and In-Kyung Kim. Feng had a 69, Lee shot 66 to match the best score of the day and Kim had a 68.
Feng won the inaugural Reignwood LPGA in 2013 at 26 under for the second of her four tour titles. In 2012, she won the LPGA Championship to become China's first major champion.
China's Simin Feng (67) and South Korea's Amy Yangwere tied for sixth at 12 under.
Second-ranked Ariya Jutanugarn had a 69 to reach 10 under. The Thai player has a tour-high five victories and will take the player-of-the-year points lead from idle Lydia Ko with a ninth-placed finish or better.
Older sister Moriya Jutanugarn, winless on the tour, also was 10 under after a 69.
Yani Tseng had her best round of the year, with birdies on the final three holes for a 66 to get to nine under. The Taiwanese player won the last of her 15 tour titles in 2012.
