It's just Phil being Phil. You know, hitting a backwards shot with a wedge.
After winning his first-ever European Tour event on Sunday at the Aberdeen Asset Management Scottish Open, Mickelson made his way down to Muirfield to prepare for the 2013 Open Championship.
On the 17th green in his practice round with Scott Piercy, Mickelson decides to try to hit the ball backward with his wedge. With the ball sitting on an uphill lie on a dune mound of wispy grass next to the green, Lefty pulls off the shot to the delight of the small crowd as Geoff Shackelford captures the footage.
This isn't the first time Mickelson has pulled off this shot. In fact, he made a famous instructional video in 2009 detailing how you can pull off the shot yourself.
By no means is it an easy shot, but it's one you can pull off with the right lie and the proper wrist action.
OK, you have no chance.
Speaking of other crazy stuff Mickelson has done already this week, according to Golf Channel's Todd Lewis, he has decided to forego the driver for the second consecutive major and carry five wedges in his bag instead.
