She did not win a tournament in the first five years of her professional career but still finished sixth on the LPGA money list in 2005 with over $1 million (U.S.) in earnings and played on the winning United States Solheim Cup team. She placed in the top-10 in four consecutive major championships from the 2005 LPGA Championship to the 2006 Kraft Nabisco Championship.

Her first professional win came in 2007 at the Evian Masters where she defeated Jeong Jang in a playoff to claim the winner's share of the $3,000,000 purse.
