Yuka Saso bogeyed two of the last three holes and settled for a two-under-par 70 in the final round of the Honda LPGA Thailand at the Siam Country Club in Chonburi, Thailand Sunday.
The 20-year-old Filipino-Japanese finished on 12-under 276 in a tie with Korean Sei Young Kim and American Allison Lee.
Saso birdied 3 only to bogey the next two holes. A birdie on 8 brought her back to even par at the turn. She eagled 10 and made back-to-back birdies from 14 only to drop a shot each on 16 and 17.
Lilia Vu fired four birdies in each nine on her way to a bristling eight-under-par 64 and a one-shot victory over Thai rookie Natthakritta Vongtaveelap.
Vu finished 72 holes on 22-under 266, shooting rounds of 66-70-66-64.
Vongtaveelap, the overnight leader, had a roller-coaster round of seven birdies against four bogeys and a double bogey to close with a 71.
Thai Atthaya Thitikul posted a 68 to place solo third on 268.
Bunched on 15-under were Georgia Hall (68), Ashleigh Buhai (70), Hyo Joo Kim (70), and Anna Nordqvist (71).
