One for the little guys: NASCAR's most memorable underdog wins

Over the seven and a half decades of NASCAR competition, the world's top stock-car racing organization has seen its fair share of underdog winners. Some of those underdogs, however, make for a better story than others. These are the four most memorable underdog wins in NASCAR history.

David Ragan, 2013 Aaron's 499

If there was ever a race that encapsulated a David vs. Goliath-esque battle, it was this one. On a rainy, cloudy day at the Talladega Superspeedway, Front Row Motorsports — still a decade away from consistent contention — saw the tandem of Ragan and David Gilliland finish 1-2. The Talladega triumph didn't come easy, either, as the two teammates had to fight off the dominant cars of Jimmie Johnson, Matt Kenseth and Carl Edwards. The win was the second and final victory of Ragan's Cup Series career, and also served as Gilliland's best career finish.

Trevor Bayne, 2011 Daytona 500

Bayne was 20 years and one day old when he somehow steered the famed Wood Brothers No. 21 Ford into victory lane at the Daytona 500 on Feb. 20, 2011. In a race that saw 16 caution flags, 74 lead changes and over 9,000 total passes, Bayne managed the tandem draft to a tee. Bayne's win in NASCAR's biggest race would end up being his only Cup Series victory as he was out of the Cup Series at the conclusion of the 2018 season.

Justin Haley, 2019 Coke Zero Sugar 400

Haley joined the list of NASCAR rain winners when he made a perfectly timed decision to stay on the racetrack during a caution period. To this day, the win is the only Cup Series victory for Spire Motorsports as well as the only victory of Haley's young career. There's plenty of time for both Haley and Spire to win again, but that rain-shortened Daytona win will always stand as the first for both parties.

Greg Sacks, 1985 Pepsi 400

If you asked the garage area who the favorite for the 1985 Pepsi 400 was, the unanimous answer would be Daytona 500 winner Bill Elliott. In the Cup Series' return to Daytona, Elliott would be the dominant car, but despite starting on the pole and leading 103 of the race's 160 laps, it would be journeyman driver Greg Sacks who would capture his first and only Cup Series win in a car that was supposed to bow out early on in the event. The DiGard Motorsports car was originally planned to be a start-and-park venture, but with both Sacks and the car proving to be capable of running up front, the team let the race play out. In hindsight, the decision was a good one as it ended up being the most monumental NASCAR upset of the 1980s.
