On the final lap, Brad Keselowski attempted to dart around Joey Logano, but Logano threw a block on his teammate that crashed them both. McDowell stayed right where he was, flat in the gas, and drove through a crash scene for a stunning upset at the Daytona 500.

A 100-1 underdog when the race began Sunday afternoon, McDowell won for the first time in 358 Cup starts when the checkered flag finally flew about 15 minutes after midnight. The race was stopped by rain for almost six hours and ended nine hours after the green flag waved at Daytona International Speedway.

NASCAR’s season opener was stacked with storylines. Denny Hamlin was trying for a record third-consecutive Daytona 500 victory, and the team he started with Michael Jordan was debuting with driver Bubba Wallace.

Kyle Larson was back after nearly a year in exile for using a racial slur, and reigning Cup champion Chase Elliott was going for his first Daytona 500 win.

And all the way at the back of the field, 1990 Daytona 500 winner Derrike Cope made what he said would be his final NASCAR start. At 62 he was the oldest driver in the field, and his upset victory 31 years ago was considered the biggest in race history.

McDowell didn’t take that title from Cope, partly because McDowell is a strong superspeedway racer capable of mixing it up with the usual suspects. 

McDowell was in the mix even before the two Penske cars derailed the finish. His Ford was strong enough to push Keselowski, and McDowell figured with the checkered flag in sight, he’d try to pass Keselowski as they exited the final turn.

Logano’s block of Keselowski — it seemed late, Keselowski had already started to pull alongside his teammate — triggered a fiery multi-car pileup that was in McDowell’s rearview mirror.

McDowell, who led less than half of a lap, drag-raced Elliott and Austin Dillon until NASCAR finally called a caution.

A batch of solid contenders were knocked from the race just 15 laps in by a 16-car accident that began at the front of the field. It thinned the pack and set up a showdown between Kevin Harvick and Hamlin.

Hamlin and Harvick had the two best cars but pit strategy ended Hamlin’s shot at winning a record third consecutive Daytona 500. The Ford drivers pitted first as a group, followed by the Chevrolets a lap later and finally the Toyotas.

But the Toyota group has just five cars and they couldn’t group back together to reclaim control of the race. It put Logano, Keselowski, and the Ford drivers out front, and Logano led the final 25 laps until Keselowski made his move.

McDowell held off Elliott and Dillon. Harvick finished fourth, and Hamlin was fifth after leading a race-high 98 laps.

Only 11 cars finished on the lead lap.
