Team Titleist caught up with Titleist Brand Ambassador Erik Compton yesterday at the AT&T National, just a few days removed from his first-career victory at the Nationwide Tour's Mexico Open.

Erik, 31, a two-time heart transplant recipient, closed with a final-round 6-under 65 at a rainy, windy El Bosque Golf Club for a 17-under 271 and two-shot victory. The win pushed Erik to No. 2 on the Nationwide Tour money list, in prime position to earn a 2012 PGA Tour card.

“My lifelong goal has been to get to the PGA Tour and now I’ve done that,” said Erik, who has now made the cut in 12 of 13 starts this season on the PGA Tour and Nationwide Tour. He is also playing in this week's AT&T National on the PGA Tour.

Check out the above video to hear more from Erik on his victory, the Pro V1x golf ball and his Titleist equipment.

As the country's top PGA club professionals gathered for their 44th national championship at Hershey Country Club in Pennsylvania, the momentum and unmatched success of Titleist across every major equipment category was evident once again.

From golf balls to drivers, fairway metals, hybrids, irons, wedges and putters, more players made Titleist their top equipment choice at the 2011 PGA Professional National Championship than any other.

Not only did more players rely upon Titleist equipment with overwhelming success at the showcase event for PGA club professionals, David Hutsell, director of instruction at the Elkridge Club in Baltimore, won with it.

Below is our final set of pictures from this week's debut of the new Prototype Titleist AP1, AP2, CB and MB (712 series) irons at the PGA Tour's AT&T National.

The seeding and tour validation process for the new Prototype Titleist AP1, AP2, CB and MB (712 series) irons is officially underway at Aronimink Golf Club outside Philadelphia.

On Monday, several Titleist Brand Ambassadors were welcomed on the range with a box of the new irons, custom built to their specifications, including: Rickie Fowler, Greg Chalmers, Graham DeLaet, Troy Matteson, Matt Jones and Jimmy Walker.

Titleist Brand Ambassadors Scott Stallings (AP2) and Bobby Gates (MB) got to Aronimink early Sunday afternoon and had already gotten 36 holes in playing the new prototypes.

Late Monday afternoon, Titleist Brand Ambassador Geoff Ogilvy stopped by the Titleist Tour Van to check out his new Prototype MB irons. Geoff didn't head to the range, given that he was wearing a T-shirt and cargo shorts, but said he was excited to hit them Tuesday. As were many other players planning on a Tuesday arrival in Philly.

Check out the slideshow below for pictures from Monday's testing, and stay tuned for more pictures and updates from Aronimink throughout the week.
