[2] Simpson's first win in professional golf came at the 1981 Cacharel World Under-25 Championship in Nimes, France.

Simpson's PGA Tour career was brought to a sudden end due to his contracting Lyme disease on a hunting trip in 1991, and the neurological pathological condition resulting from it.

In his late thirties and forties, his health improved enough to allow him to play some on the Nationwide Tour.

During his career Simpson was called one of the greatest ball strikers in the game's history by golfing greats Butch Harmon, Jack Nicklaus, and Johnny Miller.

Simpson lives in Greensboro, Georgia with son Chris and grand daughters.
