Well, that's something you don't see every day - especially on an iron shot. The head of Phil Mickelson's club just flew right off. Mickelson was playing a sand shot during the first round of the 2015 Texas Open. His club didn't even hit a bunker lip or anything. It struck the sand and the ball - and the clubhead - went flying.
That look on Phil's face! Apparently Golf Channel also picked up some audio, aired later, of Mickelson muttering, "What the heck?"
I feel your pain, Phil. Been there, done that. Except it happened to me with a driver. Brand new driver, too, about 20 years ago. I teed off on a par-5 I was hoping to reach in two; instead, my club broke in two. It snapped at the hosel and the clubhead went flying about 75 yards forward - right into a water hazard. Not a good feeling.
