After graduating from college, McPherson turned professional and competed on the
Futures Tour for four years. From 2003 to 2006 she competed in 60 events, never missed a cut, and won twice. Her fourth-place finish on the Futures Tour money list in 2006 earned her an
LPGA Tour card for the
2007 season. Her first season on the LPGA brought limited success, with a best finish a tie for 18th; she finished the season 97th on the money list. In
2008, her second year, she recorded six top-10 finishes, and finished 47th on the official money list. In
2009, McPherson recorded a T-2 in a LPGA major, the
Kraft Nabisco Championship, followed by a T-5 three months later at the next major, the
LPGA Championship. ==Professional wins (2)==
