Greens and Putting

Putting is half the game and the half nobody practices enough. The PGA Tour average for a round is around 29 putts; the average amateur scores roughly 35. Closing that 6-stroke gap is the single biggest opportunity for a recreational golfer. This page is the master index of every term related to putting, greens, and reading the surface defined on Golfing Fore All.

If you’re working on your stroke, troubleshooting your speed control, learning to read break, or trying to understand why putts behave differently on bermuda greens in Florida than on bentgrass greens in Connecticut, the terms below are your reference. Every entry links to a plain-English definition reviewed by a PGA-credentialed editor.

The Essentials

  • Green — the carefully tended putting surface where the hole is cut
  • Break — how much a putt curves due to slope
  • Grain — the direction the grass lies, which affects both break and speed
  • Line — the path the ball needs to roll to find the hole
  • Lip Out — a putt that catches the edge of the hole and spins out
  • Pin Position — where the hole is cut on the green that day
  • Flagstick — the pole in the hole — you can putt with it in since 2019
  • Putt — a stroke played on the green with the putter
  • Putts Per Round — the simplest putting stat, but not the most informative

How These Terms Relate

Reading a green is reading two things at the same time: break and speed. Break is how much the ball curves due to slope. Speed is how fast the ball will roll across the surface. The two interact — a faster green takes less break (the ball doesn’t have time to curve much), while a slower green takes more break (the ball lingers and gravity has more time to work). Reading a putt well means seeing both at once. Most amateurs read only break, miss low, and blame the slope.

On bermuda grass greens — common in the southern United States, the Caribbean, and much of Asia — you also have to read grain. Grain is the direction the grass blades lie, and it influences both speed and break. Putts with the grain run faster and break less; putts against the grain run slower and break more. The visual tell is the color of the grass — shiny side, with the grain; dull side, against. AimPoint Express is a modern green-reading method that uses feet (literally — feeling the slope through the soles of your shoes) plus a hand-aim technique to calibrate exactly how many cups of break each putt has. Plumb-bobbing is the older method: hold the putter vertically by the grip with the head hanging, line up with the ball, and the shaft shows you the fall line.

The stroke itself has its own taxonomy. The traditional reverse-overlap grip is what most amateurs use. The cross-handed (or left-hand-low) grip puts the lead hand below the trail hand and is used by many tour pros (Jordan Spieth, Justin Rose) to keep the lead wrist firm through impact. The claw grip turns the trail hand sideways and is the go-to fix for the yips. Arm-lock putting anchors the grip against the lead forearm. Belly putters and long (broomstick) putters were anchored to the body until anchoring was banned in 2016; they’re still legal if not anchored. Grass type matters too: bentgrass greens (cool-season, common in the northern U.S. and UK) are typically faster, smoother, and roll truer than bermuda greens (warm-season). Poa annua greens (most famously Pebble Beach) get bumpier as the day progresses because of the seed heads — players who tee off in the afternoon at a poa-annua course often putt on noticeably worse greens than the morning wave.

Common Questions

How do you read break on a putting green?

Look at the putt from at least three angles: from behind your ball (the standard read), from behind the hole (which reveals how the ball will be moving as it gets close), and from the low side of the line (which shows the magnitude of the slope). Break flows from high to low; steeper slopes break more. Watch other players’ putts on the same line for confirmation. The faster the green, the less break the putt will take, and the slower the green, the more it will take. Trust your first read; second-guessing rarely helps.

Why are some greens fast and others slow?

Green speed is measured by a Stimpmeter, a sloped ramp that releases a ball at a known speed. The reading is the distance in feet the ball rolls on a level section. Tournament greens often run 11 to 13 on the Stimp; club greens typically run 8 to 10; municipal greens often 6 to 8. Speed depends on grass type, mowing height (the shorter, the faster), moisture (drier = faster), rolling (greenkeepers roll greens to speed them up without cutting shorter), and grain direction on bermuda. Tour pros adjust to whatever they’re given; amateurs often struggle for the first nine when greens are noticeably faster or slower than home.

What are the yips, and how do I stop them?

The yips are an involuntary twitch or spasm during the putting stroke — a sudden, uncontrolled flinch that ruins the contact. The cause is debated (anxiety, neurological mis-firing, technique). The standard fixes are mechanical and grip-based: switch to a left-hand-low (cross-handed) grip, try the claw grip, anchor against the forearm with an arm-lock putter, or use a long (broomstick) putter. Mental tools (pre-shot routines, looking at the hole instead of the ball, counting out the stroke) help some players. The yips have ended careers (Bernhard Langer’s, Sam Snead’s twice) and been overcome by others (Tiger’s brief yip episodes were short-lived). If you have them, change the input — grip, putter, routine — until something works.

Can I leave the flagstick in when I putt?

Yes. Since 2019, you may putt with the flagstick in the hole from anywhere on the course, including the green. The change ended a decades-old debate. Whether to leave it in is a matter of preference: physics studies suggest the flagstick may help slightly on putts going faster than the optimal pace (the stick acts as a backstop), while it can hurt on putts going at perfect speed (a ball that would just topple in might be deflected by the stick). Most tour pros leave it in on long lag putts and pull it for short, makable ones.

What is the difference between bentgrass and bermuda greens?

Bentgrass is a cool-season grass common in the northern half of the United States, the United Kingdom, and Northern Europe. It thrives in cooler temperatures, can be cut very short, rolls smoothly, and is typically faster. Bermuda is a warm-season grass dominant in the southern United States and the tropics. It thrives in heat, has a coarser texture, and develops noticeable grain that affects both speed and break. Putts on bermuda generally take less break than they look — but with the grain. Bentgrass tends to look easier to read but punishes pace mistakes; bermuda forces you to factor grain into every read.

What does AimPoint actually do?

AimPoint Express is a green-reading method developed by Mark Sweeney. The basic idea: stand astride the line of your putt, sense the slope through the soles of your feet (1% slope, 2% slope, etc.), look at the hole, hold up the number of fingers corresponding to the slope and the distance, and aim at the edge of your fingers. It works because it converts the abstract problem of reading break into a calibrated, repeatable measurement. AimPoint isn’t magic — it requires practice and trust in your feel for slope — but in studies, players who learn it tend to read putts more consistently than those using purely visual methods.
