DAYTONA BEACH, Fla. (AP) — Brad Keselowski celebrated a sweep of the Daytona duels as he debuts with his new team. Keselowski took an ownership stake in Jack Roush's organization and rebranded as RFK Racing. Keselowski drove the flagship No. 6 Ford to a win in the first 150-mile qualifying race for the Daytona 500. Chris Buescher won the second race for RFK and he and Keselowski will start side-by-side on the second row Sunday. A team owned by Floyd Mayweather Jr. qualified for the Daytona 500, and 52-year-old Greg Biffle came out of semi-retirement to make the field for upstart NY Racing. Biffle will be the oldest driver in the field when he makes his 15th start in the 500.
