It’s not all purgatory. Many of Shinnecock’s greens are downright friendly with raised edges that funnel shots toward the center of the putting surface. Most however are shaped to repel shots away from the flagstick and in some cases off the green entirely. Be advised: every green features serious undulation. A few are so sloped that it’s impossible to imagine the ball stopping on its own.
Three putts are shown rolling to the hole on three different lines one ball width apart from the ball(s) next to it. Consider the center line as perfect and the others slightly imperfect. The middle ball is a guaranteed make. The others the “imperfect” ones? They’ll go in too because they’re close enough to perfect to catch the edge of the cup and lip-in.
And not insignificantly — it’s six times more important. Even if your path is good unduly opening or closing the face at impact spells doom. Catching putts across the face produces varying ball speeds. Find one impact point. My recommendation: the sweet spot.
