The competition on the PGA Tour heats up just outside Washington, DC, this week at Congressional Country Club.

A historically long and difficult course, which has hosted three U.S. Open championships and a PGA Championship, Congressional's Blue Course is a must-play track for many of the best players in the world. The field will look to build momentum this week, with the final two majors and homestretch of the 2013 season quickly approaching.

Among a pairings sheet deep with talent, 85 players in the field will trust a Titleist Pro V1 or Pro V1x golf ball for their success, more than five times the nearest competitor with 16 and more than all competitors combined.

Titleist is also the top choice in the sand, lob and approach wedge (133), and putter (51) categories.

From the Titleist Tour Van to the iconic Capitol Building tee markers and around the magnificently manicured grounds of Congressional, Team Titleist captured many of the moments earlier in the week when players like Titleist Brand Ambassador Adam Scott and Pro V1x loyalist Billy Horschel were polishing their swings and dialing in the performance of their Titleist golf ball.

Check out the video to see what Titleist Brand Ambassadors Bud Cauley, Marc Leishman, John Merrick, Ben Kohles, Jason Bohn, Brendan Steele, Erik Compton and many more were up to this week at the AT&T National.
