DETROIT -- Michael Thorbjornsen made a 26-foot putt for birdie on his last hole to shoot 7-under 63 and reach 18 under to win his first PGA Tour title by two shots at the final Rocket Classic on Sunday. Thorbjornsen started the fourth round three shots behind leader Davis Riley, whose rough start opened opportunities for the field. He's the eighth first-time winner this season on the PGA Tour and the second straight, following Jackson Koivun's victory last week at the 3M Open. Junior Amateur over Akshay Bhatia, who has three PGA Tour wins. The PGA Tour is moving to a new model for 2028, effectively creating two tours and Rocket Mortgage decided not to exercise its option to host another tournament next year.
