Dean: Take a moment, please. Under the rule as it is now, you are correct. I am proposing a change, so that the rule presumes the reality, not the opposite. Again, I challenge anyone to hypothesize a situation when a second shot is not a provisional.
Padraig: I can fathom a situation where a found ball is unplayable and re-teeing is the best option. But you don't know it's unplayable until you get there. There may be a miracle where, lo and behold, there's a clear shot back to the fairway. That's why one ALWAYS declares a provisional, in case the ball is found. Saves time having to walk back.
Jerry: You have the Phil situation correct. There is no way he would have hit a second without declaring a provisional - and he didn't. By the way, if a fan, or an opponent, found his first, I believe his provisional would not have been in play. Had it been unplayable, he'd have had have to re-teed.
