Inside look at Rory McIlroy's U.S. Open putter
Gear heads probably recognized the putter Rory McIlroy used during the U.S. Open as a Scotty Cameron for Titleist Studio Select Newport, but the new champ's flatstick has a few special features that make it unique.
The obvious feature is the finish. While the Studio Select putters available in stores are finished in a brushed chrome, McIlroy's prototype has a darker, chromatic bronze finish with black paint fill in the back instead of the standard red.
The "CAMICO" stamped into the heel portion of the flange stands for "Cameron & Company." The "GSS" on the toe stands for German Stainless Steel.
The standard Studio Select putters are made from 303 stainless steel. According to Cameron, German stainless steel is one of the best materials to use for making putters because it has such good feel, but it's too expensive to use for mass-produced putters. He makes "GSS" putters only for tour pros like McIlroy, Nick Watney and Dustin Johnson.
While he has experimented with several different putters over the past few seasons, McIlroy's go-to putter has been a Scotty Cameron Newport Fastback. However, according to the Team Titleist blog, "After a recent session with his putting instructor, Rory decided that the toe flow of the Newport GSS style was working better with his putting stroke."
Also from the blog: "The Scotty Cameron team built Rory the Newport GSS Prototype last season at the WGC-Accenture Match Play Championship. He's put it into play in a few times over the last year and has always kept it in his travel bag."
After his record-setting performance at Congressional, it's hard to imagine McIlroy benching this putter any time soon.
