Usually hole-in-ones are at least hit toward the hole on purpose. This was not on purpose.
Thanks to a little luck and a long roll, Shawn Stefani was able to capture the only hole-in-one in the five U.S. Opens that have been played at Merion Golf Club. The 31-year-old Texas native made golfing history when his tee shot rolled right out of the rough and into the cup for an unlikely ace on the 17th hole.
As you can see, Stefani's tee shot completely missed the green.
But then the ball rolled an estimated 50 feet before settling right into the cup.
