I guess what the OP is trying to hear comments of the issue here in WGT.
Allowed in reality and allowed here too .....unfortunately.
There are only a couple of spots in all WGT courses where you have fairway or rough in your putting line, St. Andrews 17 and somewhere in Merion if I remember well. I agree it is ok to punch, however the chance to find yourself in such situation is 1 in a million......BUT there are players who punch ½ of their putts no matter how far or close they are to the pin....and that annoys me the hell!!, why not practicing the putt instead?.
A champion un-friend me because I ask him to stop punching most of his putts (he was punching all his up hill putts). Those are the people who would do anything, absolutely anything to get fantastic scores...even using cheats.
Putt all the time, it makes you a better player and in my eyes a more fair player too.
