I had just sat down on my couch and turned on the TV and changed the channel to check and find out who was leading at the U.S. Open on Sunday when I witnessed the most amazing hole in one I'd ever seen.

Shawn Stefani had just hit the first ever hole-in-one at a U.S. Open at the course in Merion, Pennsylvania - and it was only the 43rd in U.S. Open history.

Stefani's tee shot on the 17th hole went completely over the green, landed in the rough to the left, then kicked right and slowly trickled back down and into the hole.  His reaction was pretty great too.

You're a PGA professional - act like you've been there Shawn!!  LOL..
