The futuristic technology behind this pro's experimental center-shaft putter (golf.com)

In December, a series of metal monoliths of unknown origin prompted a social media frenzy when they began appearing seemingly out of thin air — and disappearing just as fast. The futuristic metal structures, which measured 10 by 12 feet, befuddled scientists and drew more than a handful of comparisons to the alien relics used in Stanley Kubrick’s “2001: A Space Odyssey.”

This week, Jimmy Walker quietly began experimenting with the golf disciple of those monoliths — a bizarre-looking, center-shafted putter seemingly cut into a tiny, perfectly rectangular head shape. So quietly did Walker experiment, only the popular gear account and website GolfWRX noticed the shift during Walker’s practice rounds, later confirming that the former major championship winner plans to keep his regular Scotty Cameron putter in his bag.
