GRAND RAPIDS, United States (AFP) - American Lexi Thompson came from behind to earn her fifth career USLPGA Tour win Sunday, firing a six-under 65 for a one-shot victory in the Meijer Classic.

Thompson, who placed third at the Women's PGA Championship earlier this year, finished the week at the Blythefield Country Club at 18-under-par 266.

Her score was four shots better than the previous tournament record of 270 set at the inaugural event by South Korean's Lee Mi-Rim and Park In-Bee in 2014 - when Lee beat Park in a playoff for the title.

American Lizette Salas began the day with a four-shot lead and closed with a one-under 70. She finished tied for second at 17-under 267 with Gerina Piller, who shot a seven-under 64.

Ryu So-Yeon (66) finished three shots back in fourth place at 15-under with Kris Tamulis (68).

Brittany Lang (66) ended in sole possession of sixth place at 14-under 270.
