South Korean Park Inbee raced past her challengers with a final-round six-under 65 to win the North Texas Shootout by three shots on Sunday.
Park began the day tied with American Lexi Thompson, with three others just one stroke behind, but she vaulted in front with two early birdies and never looked back, finishing with a winning total of 15-under 269.
The victory was her second in the tournament in three years.
Park, the second-ranked player in the world entering the tournament, earned her second victory of the season to join compatriot Kim Sei-young and New Zealand's world number one Lydia Ko as the three players with multiple LPGA victories this season.
South Korea's Park Hee-young and American Cristie Kerr shot matching 66s to finish tied for second while Thompson finished at 11-under alongside Sweden's Maria McBride.
Canadian Brooke Henderson, the 17-year-old non tour member who has played her way into contention the past two weeks, managed only a two-over 73 to finish tied for 13th at six-under.
Ko experienced a rare off week and narrowly made the cut, ultimately finishing the tournament at even-par.
