He was 16 when he tied for 16th in his PGA Tour debut, 20 when he won for the first time on the PGA Tour, 21 when he won the Masters and the U.S. Open, 23 when he won the Open Championship.

Spieth needs only a PGA Championship victory to join Bobby Jones, Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods as the only players to complete the career Grand Slam.

Note: This item DOES come with a certificate of authenticity, certifying the autograph as true and valid.
