Grooves 101
What the Condition of Competition Regarding Grooves Means to You
The Condition of Competition pertaining to Wedges and Irons that was instituted by the USGA and the R&A in 2010 has caused its fair share of concern and questions among the golfing public. Callaway would like to help set the record straight, and clarify any confusion that you might have.
The Condition of Competition concerning grooves applies to play on the professional Tours and a small selection of other elite tournaments. For the vast majority of the golf played around the globe, the grooves found in existing Callaway irons and wedges are authorized by the ruling bodies until at least 2024.
Why the Rules Change?
Research by the USGA and R&A showed that modern groove configurations may allow some players to generate as much spin from the rough as they do from the fairway, potentially reducing the value of accuracy off the tee. The revised Rules are intended to restore the penalty of hitting into the rough.
The Condition of Competition was introduced only on the top professional Tours and at the Major Championships starting in 2010, and then at top amateur and other professional events starting January 1, 2014.
(A Condition of Competition is a special requirement within the Rules that is applied only in elite competitions by the USGA and R&A. Another example of this is the "one-ball condition," which requires Tour Professionals to play their entire round with the same model golf ball, a measure that is not typically adhered to during a regular round of golf.)
Are Callaway Irons and Wedges Affected?
It's important to note that the overwhelming majority of the golfing public is not affected by the groove rule until 2024. All of Callaway's existing iron and wedge models will continue to conform to the Rules of Golf until at least 2024. This includes:
Every iron and wedge ever created by Callaway, including the X Series JAWS Wedges, Diablo Edge Irons and Diablo Forged Irons.
Every Callaway Iron introduced after 2010 features grooves that satisfy the new Condition of Competition. RAZR X, RAZR X Tour, RAZR X Forged, RAZR XF, RAZR X Black and RAZR X HL Irons all meet the competition guidelines. Diablo Edge and Diablo Forged Irons also include grooves that meet competition standards. Grooves that conformed to the Condition of Competition were also available after April 1, 2010 in select Tour Authentic versions of recent iron models, including the X-22 Tour Irons, 2009 X-Forged Irons, X Prototype Irons, X Series JAWS Wedges and X-Forged Wedges.
How has Callaway tackled the Groove Rules?
As the leader in golf equipment innovation, Callaway has met the challenges set forth by golf's two ruling bodies head-on. While many golf club manufacturers will simply offer a standard V groove, Callaway has broken the mold again, delivering grooves that will provide all the shot-making control and spin that you can possibly attain under the Condition of Competition.
For those of you who must play—or choose to play—clubs with grooves that conform to the Condition of Competition, our groove design is another in a long line of breakthrough innovations from Callaway. Our designers prototyped more than 50 groove configurations, all conforming to the initial measurement protocol of the Condition of Competition. One was so good in its initial design that the USGA refined its groove parameters a second time late in the process.

Increased Greenside Control with the Tour i(s) Golf Ball
To further enhance your short-game capabilities going forward, Callaway developed the Tour i(s) Golf Ball, which has been met with overwhelming approval by our Staff Professionals around the world. How good is it?
When we asked Ernie Els to play a few holes with the prototype model, he didn't want to give it back. He put the ball in play in late 2009 at the WGC-HSBC Champions event in China, and finished second. Els even made a hole-in-one during the second round in Shanghai and said afterward: "That ball is unbelievable! This is the ball that I have been waiting for."
