ROGERS - South Korea's Choi Na-Yeon holed out from the fairway for eagle on the 16th hole en route to a two-under 69 to claim the LPGA Tour's NW Arkansas Championship. The 27-year-old Choi won by two shots, finishing the week at 15-under-par 198. It was Choi's ninth on the LPGA Tour and her second of the season. Mika Miyazato fired a four-under 67 to take sole possession of second place. Last year's champion Stacy Lewis held the outright lead prior to Choi's eagle, but her three-under 68 was not quite enough. She finished tied for third with Azahara Munoz (66) and Anna Nordqvist (70) at minus-12. World number two Lydia Ko, of New Zealand, cruised to an eight-under 63 and ended one shot further back in a tie for sixth at 11-under 202 with Paula Creamer (66) and Lee Min-jee (68).
