The range at Aronimink Golf Club filled up early Tuesday morning with many of our Titleist Brand Ambassadors, ready for Day 2 of the seeding and tour validation process for the new Prototype Titleist AP1, AP2, CB and MB (712 series) irons.

It was a nonstop workday in the Philly sun for our Titleist Tour Reps and Golf Club R&D teams, introducing players to the new prototype irons, answering questions and collecting feedback and data crucial to the tour validation process.

Some of the players who hit their new prototype irons for the first time Tuesday included: Titleist Brand Ambassdors Nick Watney (pictured below), Bill Haas, Geoff Ogilvy, Jason Dufner, Ben Curtis and Johnson Wagner. By the end of the day, several of them had already made the decision to game the new prototype irons this week at the AT&T National.

Check out pictures from Day 2 in the slideshow below, and stay tuned for more updates later today from Aronimink.
