OK, this is just getting silly.
Zach Johnson accidentally hit his tee ball as he took a practice swing with his driver at TPC Sawgrass' 18th hole Saturday at The Players Championship. The ball hit the toe of Johnson's driver and appeared to fly into the gathered crowd.
Rule 6.2b states a ball is not in play from the teeing area until a stroke is made, so Johnson was not penalized. He is well aware of that rule, too, as he's done something similar not once but twice before in front of television cameras.
