Rookie Austin Cindric Wins NASCAR Daytona 500

This was the first career Cup victory for the 23-year-old Cindric, who was promoted from the Xfinity Series.

Roger Penske had one rule at the Daytona 500 for his drivers: Do not wreck each other.

His orders were followed Sunday night when Austin Cindric worked with teammate Ryan Blaney over the closing laps to win the Daytona 500 as a celebration of Penske's 85th birthday.

It was just one year ago that Penske drivers Cindric, Joey Logano and Brad Keselowski all crashed while racing for the win on the final lap at Daytona International Speedway. It took time for tempers to thaw as Penske made his expectations clear to his drivers.
