Putting is a separate game within the game of golf. The score of par assumes that one will require two putts per hole. That is 36 putts in a par round of 72. Thus this game within a game is half of the game of golf! Golfers try to read almost every putt, but even the best find themselves engaged in a lot of guesswork out on the greens. For professional golfers, putting is crucial as all players in the field can hit the greens in regulation, or at least get close enough to chip it close to the hole. The putting is what separates the great golfers from the rest of the pack.
