Why two similar-looking putts may roll differently
Two putts may have comparable slopes yet behave differently. One variable worth checking is grain: the tendency of grass leaves and stems to lean in a particular direction. It is not present to the same degree on every putting green, and it does not provide a shortcut to reading every break.
On 14 October 2026, eight-time PGA TOUR winner Brad Faxon presented a lesson for The Golfer’s Journal on the Titleist website. His central point is to notice grain without letting it dominate the read. He highlights visual clues, including the turf's sheen and the edge of the hole.
Two clues, neither infallible
Look along the intended path. Where directional grain is pronounced, turf that looks lighter or shinier may indicate a down-grain putt: with the leaves, the ball can roll faster. A darker, duller appearance may indicate a putt into the grain, where it can lose speed sooner. Check the view from the other end. Changing light or moisture can create similar visual effects, so one bright patch does not prove anything.
The cut grass around the cup can offer another clue. Blades may lean or extend over part of the rim. Inspect it visually and do not disturb the hole. The grain may also change direction within a single putting surface, making a one-point reading unreliable.
Slope first; grain second
Read the broader contours before making a small grain adjustment. Consider the slope close to the ball and along the expected path. Choose a start line and intended pace together. On a sidehill putt, grain may reinforce or counteract some of the break, but it does not cancel gravity. With the same stroke, the ball may travel farther down-grain and finish shorter into the grain.
The USGA's agronomy guidance notes that directional grain can occur in grasses such as bermudagrass, certain bentgrasses and seashore paspalum; other grasses and maintenance practices show much less. Do not assume grass always grows towards the setting sun, a lake or the sea.
An 18-putt practice check
The following is an editorial exercise inspired by the underlying principle, not a drill presented as Faxon's own.
If the practice green shows a visible light/dark contrast, play three putts each way from the same distance on a relatively flat section. Record whether putts run beyond the cup or finish short. Avoid forcing an artificial identical stroke; observe what happens with your normal intention.
Next, find a gentle side slope and play three putts in each direction, noting the start line, the side of any miss and where the ball stops. Use the final six putts to test one deliberate adjustment at a time—either start line or intended pace—while keeping slope as the primary read. That gives 18 putts in total (6 + 6 + 6). If no grain is visible, do not invent it; use the session to practise slope and pace.
Keep a simple record of distance, surface conditions and outcome. Eighteen attempts cannot establish a precise performance benefit or a universal adjustment.
What the lesson cannot promise
The USGA's key caution is that putting-surface slope generally has the greater influence on the ball's path. Grain is a potential secondary factor, not a replacement for reading contour.
