The final round of the PGA Tour's Rocket Classic is Sunday at Detroit Golf Club, where five players, including Jake Knapp and Max Greyserman, are tied for second, just two shots back of Aldrich Potgieter's lead.

Jake Knapp broke the Detroit Golf Club course record Friday in Round 2 with an 11-under-par 61, breaking mark of 62 set Thursday at Rocket Classic.

Detroit Golf has seen plenty of low scores this week. It also has a three-way tie after 36 holes. A total of 86 golfers made the cut, a group that includes last week's winner at the Travelers Championship, Keegan Bradley.
