Scottsdale TR Putters
After learning that deep grooves slow putts more than shallow grooves, Ping made an aluminum insert for the Scottsdale TR (True Roll) featuring grooves that are shallower near the heel and toe so mishits travel nearly as far as those struck on the sweet spot. A dozen head styles are available, including classic blades and mallets. To help ensure proper fit, an optional adjustable shaft can expand the club from 31 inches to 38 inches. A free iPing Putter app, available on iTunes, works in conjunction with a special cradle designed by Ping and sold separately to help hone a more consistent stroke.

Grooves in wedges and irons are designed to create backspin while channeling away water and debris. In putters, grooves have been used to get the ball rolling more quickly.
Now, with the new Scottsdale TR putters, Ping says it has developed a grooved face insert that will help you improve distance control.
Brad Schweigert, the director of engineering at Ping Golf, says his team discovered that grooves reduce the velocity of a ball coming off the clubface. Ping found that the deeper the grooves, the more ball speed was lost.
"We kind of put two and two together and tried to design a variable-depth groove pattern with the deepest part of the grooves right in the center and shallower areas in the grooves near the perimeter," Schweigert says. "That would give you the same kind of effect as a high moment of inertia (MOI) putter that gives you the same kind of ball velocity on mis-hits."
The insert that Ping created is made from aluminum and comes in each of the 12 Scottsdale TR ("True Roll") putters.
When Schweigert and his team used a robot to test the Scottsdale TR putters, they found that if a center-hit putt rolled 35 feet, a putt mis-hit on the toe side would roll 34 feet and one mis-hit on the heel would roll 33 ½ feet.
"Karsten Solheim [Ping's founder] really created the first big breakthrough in putting with the idea of inertia and heel-and-toe weighting,” Schweigert says. “This kind of attacks the same thing. It's about trying to get more consistent ball velocity off the face."
While all of the Scottsdale TR putters will be available in 33-, 34- and 35-inch models, Ping will also be offering them with an adjustable shaft with a range of 29 to 37 inches.
Several of the Scottsdale TR putter heads will look familiar, like the Anser 2 and B60 blade. There are also some new models like the Grayhawk, a mid-size mallet with a single alignment line. All of the Scottsdale TR putters feature the same dark, non-glare finish and a shaft band that indicates which swing type – strong arc, slight arc or straight – they are optimized for. The Anser B belly putter and Carefree L long putter will only be available with adjustable-shafts, so it will be easy to get properly fit.
The Scottsdale TR putters will cost $139-$149. The adjustable-shaft versions will cost $20 more. All of the clubs will start arriving in pro shops on Feb. 1.
