ONEIDA, Wis. (AP) Katherine Kirk won the Thornberry Creek LPGA Classic on Sunday, matching Ashleigh Buhai with a birdie on the final hole for a one-stroke victory.
Four strokes ahead of Buhai entering the round, Kirk made a 10-foot birdie putt on the par-4 18th for a 2-under 70. She finished at 22-under 266 in the first year event at Thornberry Creek - the Oneida Nation-owned resort near Green Bay.
The 35-year-old Australian won her third LPGA Tour title and first in 152 starts since the 2010 Navistar LPGA Classic. She also won the 2008 Canadian Women's Open.
Kirk earned $300,000 and secured a spot next week in the U.S. Women's Open.
Buhai, from South Africa, shot a 67.
South Korea's Sei Young Kim was third at 20 under after a 63.
Thailand's Pornanong Phatlum had a 62 - the best round of the week - to finish fourth at 19 under.
