Definition: A statistical category on the pro tours and a popular method for amateurs and recreational players to rate their rounds. To achieve a green in regulation, your ball must be on the putting surface in the expected number of strokes in relation to par. The par for a hole always includes two putts, so to achieve a GIR on a par-3, you must reach the green with your first shot (on the green in one, two putts for par). On a par-4, you must reach in two shots (on the green in two, two putts for par). On a par-5, you must reach in three shots.
To claim a GIR, your ball must be on the putting surface. Being 1-inch off the green, in the fringe, but still able to putt the ball does not count. The ball must be on the putting surface.
When taking stats would it be GHEY to count GIR in relation to your handicap.
So if you get a stroke on a par 4, then hitting it in 3 would be a GIR
