Chad Ramey’s first two trips to PGA National as a professional were largely forgettable. He might have a chance to change that this week. Ramey shot a bogey-free round of 7-under 64 on Thursday in the opening round of the Cognizant Classic in the Palm Beaches. He was tied with S.H. Kim for the 18-hole lead. Kim had an eagle and five birdies. They were both one stroke up on Cameron Young, Ryan Moore, Chesson Hadley, Austin Eckroat, David Skinns and Andrew Novak. No. 2-ranked Rory McIlroy opened with a 67.
