Michael Phelps Drains a 159 Foot Putt at Scottish Pro-Am [Video]

Now that Michael Phelps is officially retired from Olympic competition, he has the rest of his life to do what retired people do:  play golf.  He's hired Tiger Woods' former coach Hank Haney to help refine his game, and it's paying off.

Phelps was recently playing in a pro-am in the birthplace of golf, Scotland.  He did something that is very rare, even among pros, when he jarred this putt of 159 feet.
