What is GIR from Rough?
Greens in regulation when the approach comes from anywhere other than the fairway. The gap to the fairway number shows how much a missed fairway really costs this player.
How it's calculated
A green in regulation means the ball is on the putting surface with at least two strokes left for par — the green in one on a par 3, two on a par 4, three on a par 5. The tour records it for every hole played, and the figure here is the share of holes meeting that condition across the season.
How to read it
Higher is better, and the gap between this and the from-fairway figure is a reasonable read on how much a player's approach play suffers out of position.
What it doesn't say
Greens in regulation ignores where on the green the ball finished, so a ball to forty feet counts identically to one to three. It also depends heavily on how far the approaches were, which depends on driving — a short, accurate driver faces easier approaches than the number alone suggests. It says nothing at all about what happened next; a high rate with poor putting still produces ordinary scores.
