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

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.

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

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.

Olympic Club is situated among San Francisco's steep rolling hills.  The fairways often cant opposite to the direction of a hole's dogleg (i.e. sloping right to left on a left-to-right dogleg).  This makes hitting the narrow fairways extremely difficult…

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