His best finish in a PGA Tour event was a solo 5th at the 1976 Ed McMahon-Jaycees Quad Cities Open.

The highlight of his career was defeating Hale Irwin in a playoff at the 1999 BankBoston Classic.

With his win, McGinnis deprived Irwin of the chance to match Chi-Chi Rodríguez's record of three straight titles in this event.

McGinnis worked as a teaching pro at Pine Forest Country Club in Summerville, South Carolina.

He was also an assistant coach for the boy's varsity golf team at Pinewood Preparatory School, the South Carolina 2006 Class AAA champions.
