Butler hits hole-in-one

Even for professional golfers, a feat such as a hole-in-one is a rare accomplishment. So much so, that in the 102-year history of the U.S. Open Championship, only 37 aces have been recorded.

Typically only possible on a par-3 hole, the ace is defined as "when a player hits the ball directly from the tee into the cup with one shot." According the Golf Digest magazine, the odds of an amateur player hitting a hole-in-one range from 5,000-12,000-to-1.

Odds aren't much better for professional players. Golf Digest's Francis Scheid places those odds at 3,000-to-1 for a PGA Tour player.

While on a golf outing at the Nevada Country Club, Howard Butler joined the relatively short list of amateur golfers to accomplish the feat. Butler teed off with his 3-wood from 155 yards on the sixth hole and was left to simply watch as the ball disappeared into the cup.

Bob Arnold and Dr. Spencer witnessed the ace.
