Novak and Griffin tied for the best round of Friday with a 6-under 66 to vault into a share of the lead. For Novak, it's a continuation of the best stretch of his career as he's coming off of a runner-up at the RBC Heritage. He seems to be carrying that positive momentum into this week.

PGA Tour rookies Isaiah Salinda and Kevin Velo shot 3-under 69 in alternate-shot play Friday to remain atop the leaderboard in the Zurich Classic.
