Ya, it's legal, orlando, just getting a little out of hand. Instead of using it as a means to overcome an unusual situation, a lot of players are doing it instead of putting because they're too friggin lazy to learn how to putt. I have to bite my tongue when some op uses it 25 feet from the hole.
I do laugh and comment when it comes up short or wide simply because the closest I've seen one of those shots get to the pin was 2.5 feet. Only once have I seen one of those shots go past the hole. I have seen a crapload of putts made from the same distances, though. Go figure. It's definitely legal but is it all that smart? :-)
