Jason Dufner set the course record at Oak Hill Country Club and tied the lowest round in a major championship on Friday, firing a 7-under 63 to take the lead at the PGA Championship.
The two-time PGA TOUR winner, and runner-up at the 2011 PGA Championship, accomplished the feat with a new set of Titleist 714 AP2 prototype irons in the bag. Dufner used the irons for the very first time last week at the World Golf Championships-Bridgestone Invitational and finished T4.
Dufner isn't the first player to have success with Titleist's new prototype irons after a few round. PGA TOUR rookie Jordan Spieth switched to the 714 AP2 irons at AT&T National and won two weeks later at the John Deere Classic.
