DETROIT (AP) — Davis Thompson tied a Detroit Golf Club record with a 9-under 63 to take the first-round lead in the Rocket Mortgage Classic. Thompson is in his third PGA Tour event as a professional. Brandon Hagy, Tom Lewis and Joaquin Niemann were two shots back. Seamus Power and J.J. Spaun shot 66, putting them another stroke behind the surprising leader. Defending champion Bryson DeChambeau got off to a shaky start, a day after parting ways with caddie Tim Tucker. DeChambeau shot an even-par 72, putting him in danger of missing the cut.
