Phil should DQ/withdraw himself after that classless , cheating, bad sportsmanlike act not to mention lying about it in the small presser after the round .
1. When interviewed after the round, his playing competitor "Johnston" said this was the conversation after walking off the green. Phil said " I don't know what score that is or what happens now"
2. After 30 minutes of chatting with his management team, USGA, PGA officials so they can clean the mess up, phil goes out to the presser and lies and says basically , I know the rules, I use them to my advantage, I did it on purpose, blah blah blah.
1. & 2. don't add up.
USGA should be embarrassed to for being cowards not enforcing the "proper rule" that fits this situation all because it was "phil"
All phil had to do was come clean and say he was pissed and lost his cool as well as embarrassed himself, his family and his fellow golfers and fans.
