Greens in Regulation (GIR)
Also known as: GIR
Greens in Regulation (GIR) counts how often a golfer reaches the green in two strokes fewer than par. It is golf's most common ball-striking measure.
Greens in Regulation, universally abbreviated GIR, tracks how often a golfer's ball reaches the putting surface with two putts left for par. That means by the second stroke on a par 4, the third on a par 5, and so on. GIR percentage is the single most commonly cited ball-striking statistic in golf. It sums up driving accuracy and distance, approach shot quality, and club selection in one clean number. That number ties directly to scoring opportunity.
GIR correlates strongly with scoring average across all skill levels. That is why serious golfers often track it first, alongside fairways hit. A golfer's GIR percentage sets the baseline for how many holes offer a realistic two-putt par (or better). The rest require the short game to save par through scrambling. Together, GIR percentage and scrambling percentage largely explain a golfer's overall scoring average.
GIR is sometimes misinterpreted as purely an approach-shot statistic. But tee shot quality heavily influences it as well. A golfer who reliably finds the fairway, with a workable distance left, has a structurally easier path to GIR. A golfer who often faces long approach shots from the rough has a harder one. That is part of why serious statistical analysis tracks GIR alongside fairways hit and approach shot proximity. It does not treat GIR as a single, self-contained number.
Example
A player hits the green in two shots on a par 4 (off the tee, then a mid-iron approach). This leaves two putts for par. A greens-in-regulation hole regardless of whether the two putts are actually made.
Why it matters
GIR percentage correlates strongly with overall scoring average. That makes it one of the most useful single statistics for tracking whether ball-striking improvements translate into real scoring opportunities.
Frequently asked questions
What counts as a green in regulation?
Reaching the putting surface in two strokes fewer than par for that hole. The second shot on a par 4, the third on a par 5, and so on — regardless of how many putts are then taken.
Is GIR the most important golf statistic?
It is one of the most commonly used and strongly correlated with scoring. But it works best interpreted alongside fairways hit and scrambling percentage rather than in isolation.
Related terms
- Fairways HitFairways hit measures driving accuracy: the percentage of par-4 and par-5 tee shots that finish in the fairway. It is a key input into greens in regulation.
- Approach ShotAn approach shot is any shot hit toward the green to reach or set up the putting surface. It is usually a par 4's second shot, or a par 5's second or third.
- ScramblingScrambling is how often a golfer saves par or better after missing the green in regulation, in any number of strokes. It is the broadest short-game stat.
- Strokes GainedStrokes gained measures the strokes a player gains or loses against a benchmark (tour average or a peer group). It covers tee shots, approach, around the green, and putting.
- Club SelectionClub selection is picking the right club for each shot from real carry distance, lie, wind, elevation, and hazard placement. It is one of the biggest scoring decisions.
