The following is the definition of Rule from the Rules of Golf. Note in particular item's b and c. All of the local rules used in PGA Tournaments conform to the Rules of golf. Even in those rare instances where relief from a temporary immovable obstruction results in moving the ball closer to the hole, it is done for the sole reason that no other playable option is available. Such rulings are made only in a case of extreme necessity, and as such are approved by the USGA.
Which is exactly what I said. Because they are allowing for them, for whatever reason, to breach the rules of golf.
How can you say that? Approved local rule s ARE rules of golf, so how can they also be breaches? And they are allowed for ANY competition, not just PGA Tour. My Men's Club uses a couple of local rules from the list. That doesn't change the Rules of Golf, it only addresses some local conditions which are not encountered on every course. They are NOT breaches of rules, they are simply extensions to the rules which are applied for special or unusual circumstances. Just like the allowance in most competitions and courses these days for using GPS or laser rangefinders. They are not a breach of Rule 14 when implemented, they are an extension of it. They can't be both a rule and a breach of a rule at the same time. Local Rules ARE rules. When a tournament specifies conditions of the competition, those conditions are rules too (like the one ball condition which the Tour uses).
If you want to argue that the PGA Tour takes the implementation farther than the original intent of the local rule, I won't dispute that. They use the local rule allowing the extension of the embedded ball ball rule from closely mowed areas to through the green as a standard policy. I disagree with that. It should only be used when actual conditions warrant, but the Tour tends to baby its members bit too much.
