From 1978 to 1980, he was a three-time All-American and two-time Collegiate Golfer of the Year at Brigham Young University.

He finished 2nd at the 1983 Air New Zealand Shell Open, an official event on the Australasian Tour.

After recording a victory and nine top-3 finishes in his first two seasons as a pro Clampett abruptly changed his swing with devastating results.

Clampett admitted in interviews to being emotional because of how well his opening round went, and although he did not shoot better than 76 the rest of the tournament and tied for 37th, he still enjoyed a warm reception from crowds throughout.

On April 11, 2008, Clampett apologized for referring to golfer Liang Wenchong as "the Chinaman" during the Masters Tournament at Augusta National Golf Club.

Clampett, working the Internet broadcast of Amen Corner, made the comment after Liang missed the cut.

Clampett and Andy Brumer co-authored the book "The Impact Zone: Mastering Golf's Moment of Truth", published in late 2007.

He has three children from his first marriage: Katelyn, Daniel, and Michael Clampett; and Marianna has two of her own: Nicholas and Anna Suciu.

As host Bob Barker was about to make his "inspiration putt" in the Hole In One game, he decided instead to ask Clampett to come up on stage to do it.
