Through Line

The projected path that a putt would travel if it missed the hole and continued rolling past the cup, used by golfers to read putts and understand green slopes. Analyzing the through line helps players understand how the ball will break and what speed is needed to hold the intended line to the hole. Professional golfers and their caddies carefully study through lines to determine optimal putting strategies, especially on putts with significant break. Understanding through lines also helps with distance control, as knowing where the ball will go if it misses can influence the aggressiveness of the putting stroke.
