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.

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).

Just hours after his World Golf Championships victory at Firestone, Titleist Brand Ambassador Adam Scott flew straight to Atlanta, checked into his hotel and went to bed, getting in some rest from a long week in order to get ready for another.

"It was pretty lame, actually," Adam said, laughing. "Maybe we'll save the celebration for after this week."

Perhaps Adam's fireworks on the back-nine Sunday at Firestone were sufficient.

Trusting a Pro V1 golf ball and a bag full of Titleist equipment, Adam closed out the tournament with a four-birdie, zero-bogey 31 on the back nine and ran away with a four-shot victory.

Tuesday at the PGA Championship, Adam checked in with Team Titleist to talk about some of the key shots he hit down the stretch at Firestone.

Check it out in the above video.

This week's winning formula at Atlanta Athletic Club: Hitting drives down the middle, and (lengthy) approach shots as high and soft as possible. In other words, beware the long rough and firm greens.

(Of course, solid putting will also help.)

Check out our slideshow from Tuesday at the PGA Championship to see how our Titleist Brand Ambassadors and Titleist Staff Professionals are dialing in their games for the year's final major.

The heat is on (and pushing 100º) at Atlanta Athletic Club, but it isn't keeping the world's best players (like Titleist Brand Ambassador Nick Watney, pictured below) from preparing for the season's final major.
