Reply To: Flagstick

[William Aleshire Jr.]

Dave Pelz: Original Pin In/Pin Out test in 1990, and published the results in the December issue of GOLF Magazine. The testing was performed with a special putting device built to roll putts accurately aimed with a laser—and a true, pure roll—from two feet away. We rolled putts at different speeds hitting different parts of the pin on flat, uphill and downhill sloping greens. The test results were conclusive: You will hole a higher percentage of putts when you leave the flagstick in.

The reason for this effect is that a significant amount of energy is lost from a putt’s speed when the ball hits a fiberglass flagstick. The speed-loss enables gravity to pull the slower moving ball down into the hole more often. Even though balls have changed since my testing, holes and flagsticks have not, and the “energy-loss” effect will still win the day.

To make you feel better about leaving the pin in, think about how many long putts and chips you’ve seen crash into the pin and still stay in the hole. If you’re watching golf on TV, you’ve also seen several shots fly into the hole directly from the fairway and stay in.
