The 19-year-old Harigae, from Monterey, Calif., opened with rounds of 68 and 66 en route to an 11-under 205 total on the Crooked Creek course.
I have good vibes here because its so pretty and the people are awesome, said Harigae, the 2007 Womens Amateur Public Links winner at Kearney Hill in Lexington. I like it here in the Bluegrass State.
Harigae earned $14,000 to top the season money list with $73,897, with the top 10 at the end of the season earning 2010 LPGA cards.
She also became the first player to benefit from the new three-time Futures Tour winner category in the LPGAs 2009 priority list, giving her the opportunity to compete in non-limited-field LPGA events.
Winning three times out here is hard, Harigae said. But its also possible. I think this new rule by the LPGA is a great thing.
Harigae turned pro after less than a semester at Duke.
She really is a very solid player, Blumenherst said. Shes a great putter and shes consistent. It was going to take some work to beat her.
Blumenherst birdied the final three holes for a 70, and Lindberg eagled the 18th for a 66. Lindberg joined the tour this year after her senior season at Oklahoma State.
Canadas Samantha Richdale shot a 64 to tie for fourth with Hannah Yun (69), Yoora Kim (70) and Gerina Mendoza at 7 under.
