The Vokey Tour Department has been buzzing lately, and it has to do with much more than the sound of the grinders.

In just two weeks, new Prototype Titleist Vokey Design SM4 wedges, the next generation of Spin Milled wedges from Master Craftsman Bob Vokey, will be making their PGA Tour debut at The Barclays.

Bob and his team in Carlsbad, Calif., have been busy the last few weeks grinding, shaping and finishing the new prototype wedges to the custom specifications of our Titleist Brand Ambassadors.

For the last year, Titleist Brand Ambassadors such as Adam Scott, Nick Watney and Rickie Fowler have been taking part in the testing and performance validation process for the Prototype SM4 wedges at Titleist's Oceanside (Calif.) Test Facility, offering ongoing feedback on a new groove design and profile improvements, as well as new lofts, bounce options and sole grinds.

At The Barclays, Bob, Vokey Tour Rep Aaron Dill and Director of Wedge Development Rick Nelson, will be working with players to get them dialed in to the new Prototype SM4 wedges and capture additional feedback.

We will continue to provide behind-the-scenes information and product details here on the Team Titleist blog throughout the seeding and performance validation process.

The new SM4 wedges are scheduled to be available for purchase in mid-November.

Team Titleist had a great time hanging out with Titleist Staff Professional Darin Stinson Wednesday afternoon at the PGA Championship.

Darin, the Head PGA Professional at Atlanta Athletic Club, gave us a lot of great insight into this week's major venue and the types of shots you need to be able to hit to succeed here, which you can watch in the above video.

One of 11 PGA Professionals at Atlanta Athletic Club, Darin also spoke about what it means to be the host PGA Professional at a PGA Championship, the PGA's flagship event. This year, 20 PGA Professionals are taking on Atlanta Athletic Club, having qualified via their finishes in the PGA Professional National Championship. Titleist Staff Professional David Hutsell, the PGA Director of Instruction at the Elkridge Club in Baltimore, won the event.

In total, there were eight Titleist PGA Staff Professionals in this week's field:

David Hutsell (Elkridge Club, Baltimore)
Faber Jameson (Falling River CC, Appomattox, Va.)
Danny Balin (Burning Tree CC, Greenwich, Conn.)
Rob Moss (Pepper Pike Club, Pepper Pike, Ohio)
Craig Stevens (Steel Canyon GC, Sandy Spring, Ga.)
Todd Camplin (Pinehurst Resort & CC, Pinehurst, N.C.)
Stuart Smith (Somersett CC, Reno, Nev.)
Dan Olsen (Walnut Hills CC, East Lansing, Mich.)

 Not long after Titleist Brand Ambassador Rory McIlroy damaged his Titleist MB 7-iron early in his round Thursday at the PGA Championship, a new one was already being assembled in the Titleist Tour Department in Carlsbad, Calif., just in case.

Rory damaged his 7-iron when hitting a tree root on Atlanta Athletic Club's par-4 third hole. He then handed the club off to a tournament official to bring it in for possible repairs.

Chris Tuten, Titleist Golf Clubs' Director of Tour Promotions, didn't want to take any chances. He immediately called in an order to the Titleist Tour Department for a new Titleist MB 7-iron with Project X 6.5 shaft, built to Rory's specifications: 1º upright, D2 swingweight, Golf Pride MultiCompound Yellow 58 Round grip.

(Per routine tournament regulations, The Titleist Tour Van left the property Wednesday afternoon along with all other club manufacturer vehicles.)

The 7-iron was shipped via overnight delivery, leaving Carlsbad at 4:28 p.m. (EST) and making stops in Memphis, Tenn. (11:53 p.m), Atlanta (3:50 a.m.), and Alpharetta, Ga. (4:30 a.m.).

The club arrived at Atlanta Athletic Club (Johns Creek, Ga.) at 7:25 Friday morning and was delivered immediately to Rory's locker.

Also sitting in the locker: Rory's damaged 7-iron, which had been deemed irreparable.

Just after 8 a.m., about 18 hours later, Rory was on the driving range with the new 7-iron in his bag, his right wrist and forearm heavily taped to support the strained tendon he suffered from hitting the root.

Rory, who despite the injury went on to shoot an even-par 70, teed off in Round 2 at 8:35.

As you'd expect, Atlanta Athletic Club's practice areas were jam-packed Wednesday as players dialed-in their games for the PGA Championship. The galleries were just as crowded, especially toward the right side of the driving range, where Titleist Brand Ambassadors Matteo Manassero and Rory McIlroy were practicing in adjacent spots (pictured below).

Check out Team Titleist's pictures from the day in the slideshow below, and stay tuned tomorrow for a few more updates from the week.

Titleist Staff Professional Rob Moss, the Head PGA Professional at Pepper Pike Club outside Cleveland, Ohio, is back at the PGA Championship for a third time this week at Atlanta Athletic Club.

Team Titleist caught up with Rob, a three-time Ohio Open champion, on the putting green Wednesday afternoon to talk about his strategy for taking on this major championship venue and his overall experience this week, which you can watch in the above video.
