What is a putter in golf?

Definition

The specialized golf club designed specifically for rolling the ball on putting greens, featuring a flat-faced club head, upright lie angle, and minimal loft to promote smooth ball roll. Modern putters come in various designs including blade, mallet, and high-MOI configurations with different alignment aids, materials, and weighting systems. Putter fitting considers factors like length, lie angle, loft, and head design to optimize performance for individual putting strokes. The putter is often considered the most important club in the bag, as putting accounts for approximately 40% of all strokes in a typical round.
