Wei-Ling Hsu carded a 4-under 67 on Sunday and won the Credit Union Challenge by two strokes.
Hsu ended her first Symetra Tour title at 11-under-par 202.
The tour rookie bogeyed the third, but came back with birdies at eight and nine to make the turn at minus-8. Hsu jumped ahead of the pack with three birdies in a 4-hole span from the 14th. She parred the last to earn the victory.
Kendall Dye (68) and second-round leader Olivia Jordan-Higgins (72) shared second place at minus-9. Dye had moved to 11-under with a birdie at 15, but bogeyed 16 and double-bogeyed 17 to fall back to 8-under. She birdied the last to tie for second.
Hannah Jun carded 67 to move into a share of fourth place at 8-under 205. She was joined there by Catherine O'Donnell, who closed with an even-par 71.
