Hoffmann’s 8-under-par 62 eclipsed the Cherry Hills competition course record by two shots.
“It's such an honor, especially with all the history here and all the great championships that have been played here,” Hoffmann said. “It's really cool.”
Hoffmann started the day tied for 53rd and said he teed it up with the attitude that he had nothing to lose. He didn’t back off that after making birdies at eight of his first 12 holes.
“My goal is to go as low as possible,” Hoffmann said. “I don't think you should be out here if you're scared to go low. It was kind fun for me.
“That 59 number was a big goal for me, and it was possible, with three more birdies coming in. But, hopefully, I can pull it off tomorrow.”
With his big day, Hoffmann was among the top 10 on the leaderboard when he signed his scorecard. He is 68th in FedEx Cup points and likely needs to finish the BMW Championship third or better to advance to the Tour Championship in Atlanta next week.
“My goal all year has been to get into the finals and Atlanta,” Hoffmann said. “So, those first two rounds really hurt me, but, hopefully, a good one tomorrow can propel me up there.”
