France's Celine Boutier carded an even-par round of 72 to win the LPGA's Vic Open by two strokes in Barwon Heads, Australia on Sunday, after American Kim Kaufman blew her overnight lead following a 6-over-par 78.
Boutier made three birdies and as many bogies as she finished on 8 under overall, ahead of Australian duo Sarah Kemp and Su Oh and England's Charlotte Thomas on 6 under.
Kaufman, who started Sunday's final round two shots clear on 12 under, opened with a birdie at the 1st hole, but quickly faded following bogeys at the 3rd, 4th and a double-bogey 7 at the par-5 5th.
Further dropped shots at the 10th, 13th and 17th saw Kaufman finish in a tie for eighth, after she had started the week with consecutive rounds of 66.
Australian Kemp shot a 7-under-65 to card the lowest round of the day, despite starting with a double bogey on the 1st. Compatriot Katherine Kirk, Japan's Haru Nomura and Spain's Azahara Munoz, who also flew up the leaderboard following a round of 66, finished in a tie for fifth.
In the men's event, Briton David Law produced a sparkling eagle on the 18th hole to snatch a one-stroke victory and claim his maiden European Tour title.
