Shawn Stefani may not have won the U.S. Open, but he did have a pretty sweet moment.

Stefani sunk the first ever hole-in-one at a U.S. Open at the course in Merion, Pennsylvania.  And only the 43rd in U.S. Open history.

His tee shot on the 17th hole - a 213 yard par 3 - went completely over the green, landed in the rough, then slowly trickled back down and into the hole. His reaction was pretty great too.
