Kevin Roy and Aldrich Potgieter each shot 10-under 62 on Thursday to break the Rocket Classic record and share the first-round lead.
Detroit Golf Club has been one of the easiest courses since the PGA Tour made it an annual stop in 2019. A pair of Korn Ferry graduates took full advantage.
Potgieter, the 20-year-old South African who grew up in Australia, started at No. 10 and set a tournament record with a 7-under 29 on the back nine. He added three birdies on his back nine and caught the left edge on a 12-foot putt on his final hole that would have given him a 61.
