Thirty players were greeted with letters from the R&A ordering them to offer up their drivers for a COR test. It's not clear if the tests were random or if the players were specially chosen by their manufacturer affiliation or driving distance average.
Welcome to Scotland!
Tim Rosaforte reports for Golf Channel on what appears to be a step-up in the effort to ensure there are conforming drivers in this week's Open Championship.
Keegan Bradley, Brendan Steele and Brooks Koepka all confirmed that their drivers all passed the COR test (coefficient of restitution, or spring-like effect) administered by the R&A.
This was the first time the R&A took measures that were not part of the distance insight project being done in conjunction with the USGA.
There are two ways of looking at this.
The sunny side up take would believe this is just part of normal monitoring and amidst some rumblings that this year's distance increase could be fueled by hot drivers.
The cynical take says this is the act of a desperate governing body looking for something to blame this year's increases on, instead of simply anticipating that a combination of technology, athleticism, fitting and a generation of players reared on modern clubs have passed the testing procedures by. AKA, anything not to do something about the Joint Statement of Principles.
