Kelly Moser is always a popular guy during majors weeks.  Here he is unveiling one of the very first Scotty Cameron 2012 U.S. Open putter headcovers.

Titleist Brand Ambassador Bill Haas is making his fourth appearance at the U.S. Open this week.

Titleist Brand Ambassador Zach Johnson is also playing well heading into the Open.  He recently edged Jason for a big win at the Crowne Plaza Invitational at Colonial.

The 712 Series AP2 irons used by Titleist Brand Ambassador Ben Crane.  Check out the throwback headcovers on his fairway metals.

Zach played a practice round today with fellow Titleist Brand Ambassador Steve Stricker.

Defending champion, Titleist Brand Ambassador Rory McIlroy, is looking to recreate the magic he delivered last year at Congressional.

Titleist players arrived early on Wednesday morning to prepare as much as possible for the test that awaits them beginning Thursday.

Jason loves to experiment with his equipment and is a regular in the Titleist Tour Van.  With frequent adjustments, sometimes it pays to add a few notations on headcovers, as Jason did here with his 910F 13.5 degree fairway metal.

Rory arrived with a determined sense of purpose on Wednesday and spent a good deal of time honing his putting routine.

After his practice round, Bill shared some time with his growing fan base.
