We spotted a new “Antidote Model 2″ tour prototype putter from Bettinardi at the 2017 WGC-Bridgestone Invitational on Tuesday.


Sam Bettinardi, Vice President of Bettinardi Golf, calls the putter an Antidote Model 2 and says the back weights — they’re milled from aluminum, stainless steel and copper, and they’re adjustable to make the putter weigh 340, 350 or 360 — are strategically positioned on the rear heel and toe to increase MOI (moment of inertia, a measure of forgiveness). The weights are also positioned “equal with or above the equator of the golf ball” to raise the center of gravity.


“(Bob Bettinardi) knew there would be players that wouldn’t find the design the most appealing, however, he feels that this is one of his more technologically sound designs he has produced,” Bettinardi says.

According to Bettinardi, we can expect to see more designs with the “Antidote technology” later this fall.

  1. I do think the technology here is sound. The looks are a bit on the harsh side. But I think they could refine it, maybe decrease the overall size about 10%, then add a slant neck or something.
