CHONBURI, Thailand (AP) -- Amy Yang of South Korea won her second career women's tour title at the Honda LPGA Thailand at the Siam Country Club Pattaya Old Course on Sunday.
Yang, who won her maiden title on home soil in Incheon in 2013, finished two shots ahead of overnight leader American Stacy Lewis, two-time champion Tseng Yani of Taiwan and South Korean Mirim Lee.
Yang's final round included five birdies with two bogeys for a 69 and an aggregate 15-under 273.
Lewis, who started the day with a one-shot lead, battled Yang throughout the round but fell away on the 15th where she carded a double bogey as her opponent picked up a birdie.
"I was a little bit nervous out there, but I tried to focus on how low I can go today, just focus on my game," said Yang.
Former top ranked player Yani fired a bogey-free 67 to settle for a share of second place.
"I played good, but I missed bunch of putts out there. I was just actually a little nervous out there when I was putting," Yani said.
Lewis signed off with an even-par 72, with three birdies against a bogey and a double bogey.
Spaniard Beatriz Recari had 11 birdies and two bogeys for the year's lowest round at 63, which equaled the course record achieved by five other players, including Lewis and Yani in 2013. Recari finished joint fifth along with South Korean Sei Young Kim on 276.
Inbee Park, the 2013 champion and former world No. 1, fired a bogey free 65 for a total 277 to share seventh place with 2007 winner Suzann Pettersen of Norway and German Sandra Gal.
