Stefani's ace on 17 was the first ever at a U.S. Open at Merion and the 43rd in U.S. Open history. What sets it apart from most is that Stefani flew his tee shot completely over the green, landed the ball in the rough and then watched it trickle down into the hole.
Shawn Stefani's hole in one reaction was one for the ages. https://t.co/P4JPq3pq5Y
