South Korea's Na Yeon Choi held off the charge of Yani Tseng to win the LPGA Malaysia by a single stroke.

The pressure was on as world number one Tseng surged to a six-under-par round of 65, but Choi sunk a crucial birdie at the 17th and backed it up with a par at the last to keep the overnight advantage she had held and end up fifteen under par for the tournament.

Azahara Munoz's consistent week ended with a round of 69 to finish third on twelve-under-par, with Se Ri Pak of Korea fourth two shots further adrift.

American duo Brittany Lang and Stacy Lewis faded to share fifth place.

It was Choi's first victory on tour this season, and her fifth in the last three years.

The result marked a reversal of the order the previous week, when Tseng held off Choi by the same margin at the LPGA Hana Bank Championship.

"I took something from last week," Choi said. "I had a great experience from last week. ... I did my best last week. ... So, I learned something. And then this week, I had a great feeling about my game. I played so well this week.

"I won my fifth tournament and a hundred times for all of the Korean players. So it's very nice. Icing on the cake."

"Na Yeon played great and she made a couple birdies on the back nine," said Tseng, who has already won six titles this season. "I finished second this week - that means I still have space to improve next week."
