Has to do with placement of marker.....he dropped his marker which in turn moved the ball. He moved the ball back, but still subject to the one stroke penalty......
Honestly, while Phil is one of my least favorite on tour, I would surely never wish him ill-will. I am honestly concerned about him. He's not playing much (or it seems that way....as I said not a fav so don't following him closely).....and when he does play he appears not to be in control of his swing and even his putter. If his psoriatic arthritis is increasing it would explain a lot.
