GALLOWAY, 31 May 2015 (AFP) - It marked the third win for Nordqvist since February 2014 and the fifth of her career on the US LPGA Tour.
Nordqvist finished at eight-under 205 to beat Christel Boeljon, of the Netherlands, by one stroke at the Stockton Seaview Golf Club course.
Boeljon closed with a three-under 68 to grab second place at seven-under. Morgan Pressel, who led after the first two rounds, stumbled to a two-over 73 to fall into a share of third at five-under-par 208. She was joined there by fellow American Kelly Shon (70).
Nordqvist posted consecutive birdies at number 16 and 17 to help seal the victory.
Boeljon recorded her best finish on the tour but she missed a birdie putt on 18 which had the potential to get her into a playoff.
Austin Ernst fired a seven-under 64 to leap into a share of fifth after making the cut on the number. Ernst tied with Australia's Karrie Webb (66), Park In-bee (68), Lee Mi-rim (69) and Gerina Piller (71) at four under.
Stacy Lewis, the 2014 winner, managed a one-under 70 and tied for 51st at two- over-par 215.
