That's Titleist Brand Ambassador Bud Cauley, hard at work on the putting green at TPC Scottsdale.

Bud rolls his Pro V1x with a Scotty Cameron Newport 2 Studio Select.

He's also got new Titleist MB (712 Series) irons in the bag.

On approaches from 50-75 yards this season, Bud's average is 4-feet-7-inches from the hole.

Graham DeLaet uses a new Vokey Design SM4 wedge to help stretch his back before a range session.

Out on the course, Titleist Brand Ambassador Brendan De Jonge gets ready to hit his tee shot at TPC Scottsdale's par-3 16th, perhaps the most exciting hole in golf.

Hunter plays new Titleist AP2 (712 Series) irons and SM4 Vokey wedges. Why "HUCK?" Hunter's full name is Hunter Jefferson Huck Finn Haas.

A peek into Graham's bag.

Also limbering up...

...is Titleist Brand Ambassador Kyle Thompson, a graduate of the 2011 Nationwide Tour.
