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.
We're working on getting video of the shot (Edit: we've replaced the GIF with video, courtesy of Bleacher Report), but for now enjoy the GIF and especially his reaction, which was awesome.
Shawn Stefani's hole in one reaction was one for the ages. https://t.co/P4JPq3pq5Y
