“I would take that 6-under any day. In the beginning I made, on the first hole I made a 12-footer for par on the fringe. I just kind of kept the confidence with the putter going,” said the American.

“I thought off the tee I didn’t do so great, kind of missing fairways with the driver early. But here, you don’t hit too many drivers. You hit a lot of irons off the tee, hit a lot of 3-woods off the tee. So I thought those I did well. But hopefully I can clean up the driver on the weekend.”

Suh seeks a first Tour title in his 49th start since making his debut at this event in 2019.

Japan’s Hideki Matsuyama posted the low round of the week, a 65, and the only bogey-free round this week to move into second place at 7-under.

“I made some good par saving putts today, and as you mentioned, the course is playing tough, especially the greens,” said Matsuyama. “If the greens get even harder than they are now, it’s going to be a challenge this weekend. But today the putts went in and so I’m satisfied.

“I really like this golf course. I wish I could play it more in a non-tournament setting because it’s just fantastic here. But it is a difficult golf course and that’s the big challenge.”
