On an average day, with an average golfer, the odds of hitting a hole in one is about 12,500 to 1. For professional golfers, the odds of a hole in one fall significantly to 3,000 to 1. Most hole in one shots are similar – the ball, which is 1.68″ in diameter, lands on the green, rolls towards the cup, which is 4.5″ in diameter, and then falls in, which is then followed by vigorous celebration and high fives all around. So then, what do we think the odds are of a golfer of any skill level making a hole in one on the fly? Meaning, that 1.68″ diameter ball doesn’t touch the green and literally lands right in the 4.5″ diameter hole. The odds have to be astronomical. And that is exactly what happened at this weekend’s PGA Championship when Michael Block, a golf course pro from California (not even a PGA Touring pro!!), aced the 15th hole at Oak Hill Country Club in Rochester, NY. Take a look at the video. It is a stunning shot. It even took Mr. Block several minutes for it to register that he aced it.
