Aldrich Potgieter took a peek at the leaderboard before lining up his last putt on a crest of the ninth green, knowing he had to make the 12-footer for birdie to break a tie with Kevin Roy .
The putt grazed the left edge, with Potgieter missing an opportunity to cap a record-setting day by taking the outright first-round lead at the Rocket Classic on Thursday.
"I was real eager to make that putt," he said.
Potgieter and Roy each shot 10-under 62 to break the tournament 18-hole record.
Detroit Golf Club has been one of the easiest courses since the PGA Tour made it an annual stop in 2019.
