Chonburi, Thailand (SportsNetwork.com) - Amy Yang closed with a 3-under 69 on Sunday as she rallied to win the Honda LPGA Thailand by two strokes.

Yang finished at 15-under-par 273 to earn her second LPGA Tour win. She has finished inside the top-5 in four of her last five LPGA Tour starts dating to the end of the 2014 season.

"Oh, my gosh, it feels great. I don't know what just happened today. I was actually so nervous out there, but I tried to focus, do my best one shot at a time," Yang exclaimed. "It feels sweet."

Stacy Lewis, who led after each of the first three rounds, stumbled to a costly double-bogey on the 15th at Siam Country Club. She managed an even-par 72 and ended in a tie for second place at minus-13.

Lewis was joined there by Yani Tseng (67) and Mirim Lee (69). Tseng has finished inside the top-7 in all seven of her starts at this event.

Beatriz Recari fired a 9-under 63, the low round of the week, and shared fifth place at 12-under-par 276 with Sei Young Kim (65).

Suzann Pettersen (67), Inbee Park (65) and Sandra Gal (73) were one stroke further back at minus-11.

Yang birdied the first to join Lewis at minus-13. However, Lewis answered with a birdie on No. 3. Lewis stumbled to a bogey at the fifth before Yang made birdie at the sixth to grab the lead.

Both Yang and Lewis birdied the seventh as Yang kept her one-shot advantage. Yang pushed her lead to two with a birdie at the 10th.

There was another two-shot swing at the 14th, as Lewis converted a birdie try and Yang tripped to a bogey. They were tied at 15-under, but trouble loomed for Lewis.

Lewis struggled to a double-bogey on the par-4 15th to slip to minus-13, while Yang birdied the same hole to grab a three-stroke lead.

Yang 3-putted for bogey from the fringe at the 16th, trimming her lead to two. She parred the final two holes to earn the victory.

"I worked hard in this offseason and I really wanted to come back and play well," said Yang. "It came earlier than I thought. It's great. I'm going to keep working hard."

Lewis also parred the final two holes to end two behind.

Tseng birdied the second, then ran off four pars in a row from the third. The 2011 and 2012 winner poured in three straight birdies from the seventh to jump to minus-12, then parred the first eight holes of the back nine before closing with a birdie at the last to share second place.

"I played good, but I missed a bunch of putts out there. I was just actually a little nervous out there when I putting. I don't know, just maybe thinking a little more on my putting than others," admitted Tseng. "But I got some lucky bounces and made birdie on the last hole so I was very happy."

Lee stumbled to a bogey at the third, but she came back with three birdies in a four-hole span from the fifth. Lee climbed to 13-under with a birdie at the 11th. She traded a bogey at 17 for a birdie at the last.
