Woodland followed up on his opening 64 with a bogey-free 65 for a two-shot lead when he finished early on Friday afternoon.
"I'm very comfortable with where my game is right now," Woodland said. "I drove the ball in the fairway all day today."
Woodland's stats from the first two rounds are nearly identical. He hit 11 of 14 fairways in Round 2 – one more than Thursday – and hit the same number of greens (16) and took the same number of putts (28) in both rounds.
Woodland credited his work last week with instructor Butch Harmon.
"We changed a little bit with the putting, and I've seen putts go in the last two days more than I've seen all year," he said. "We're excited about where we're at and hopefully have a big weekend."
