McIlroy of Northern Ireland recorded four birdies against one bogey while carding a 68. The World No. 1 had three birdies on the front nine. His bogey was on the 14th hole.

Most frustrating to Woods was his performance on No. 13, when he needed four putts to complete the hole.
“That was a lot of shots. I hit the ball quite a few times, especially on the greens, and it was a long day,” Woods told reporters after the round. “I didn’t putt well today at all. I didn’t have a feel for it, I didn’t see my lines, I couldn’t feel my pace and I was just off.”
Talor Gooch (64 on Saturday), Max Homa (65) and South Korea’s Sung Kang (70) are tied for eighth at 7-under 206.
