Jack Nicklaus, arguably the greatest golfer of all time has a grandson named Gary. On Wednesday, at the Par Three Tournament, which is played prior to the Masters, Gary Nicklaus did something he had never done before…

He made an ace. Watch.

Now listen to the incredible shot as narrated by nine-time major champion Gary Player.

Jack Nicklaus won 18 majors, which is more than any other golfer in history. Choking back tears, he said after his son’s ace that it is now the number one memory of his entire career.

How cool is that?
