Hetherington joined the LPGA Tour in 1997, making the cut in 25 of the 28 tournaments she played that year.

Her greatest year to date was 2003, when she won twice (earning back-to-back titles for the second time in her career), finished in the top ten 11 times and earned over $900,000 in prize money.

Hetherington married former Australian Test cricketer Greg Ritchie in January 2009.
