DAYTONA BEACH, Fla. — Brad Keselowski had his confidence shaken at Daytona International Speedway more than once.
He was a good plate racer, but never could find his way to victory lane at NASCAR's most famous track.
That changed Saturday night with a dominating performance that gave Team Penske its 100th career Sprint Cup Series victory.
More important, it gave Keselowski his long-awaited first win at Daytona.
Keselowski led a race-high 115 laps then held off Kyle Busch on a two-lap shootout that sent the race into overtime for one additional lap. It gave him his fifth career Cup win in a restrictor-plate race, but all the others had come at Talladega. He won on the Alabama track most recently in May.
"I don't care if it's not the 500. It's Daytona. This is huge," he said. "I love this place."
He loved it even when he came up frustratingly short, or not even close at all.
Keselowski said his futility at Daytona was "a kick in the you-know-what," but he and his No. 2 Ford crew kept chipping away at it even after he had a disappointing run in the season-opening Daytona 500.
"I got down on myself here," he said. "We came down here for the 500 and quite honestly we ran like dog crap, but my team worked on it. I didn't give up on them. I believe in my team and my team believes in me and we went to work and we put together a better car, and it really showed with a great effort from the whole team. I'm really proud of everybody."
The race was marred by a 22-car accident that collected more than half the field and thinned the competition for Keselowski. It really only left Kyle Busch as a legitimate contender, but a restart for a two-lap shootout that sent it into overtime forced Keselowski to earn the win.
He easily held off Busch, and challenger Kurt Busch was eliminated when he was knocked out of line by Joey Logano as they headed to the checkered flag.
Trevor Bayne finished third and was followed by Keselowski teammate Logano and Ricky Stenhouse Jr. as Ford drivers took four of the top five spots.
Keselowski credited a push from his teammate for helping him shake the Busch brothers on the final restart.
"I was able to get Brad a good push to clear and get a Penske car to victory lane, which is really cool," Logano said. "The 2 was the fastest car and he deserved to win the race."
It was a plan to work together and disrupt the Toyota contingent that used teamwork to dominate the Daytona 500. Instead, Kyle Busch was the only Toyota driver to finish inside the top 10.
Kyle Larson was sixth and the highest finishing Chevrolet. He was followed by Austin Dillon, who ended last year's race in an airborne accident, then pole-sitter Greg Biffle and Clint Bowyer.
Michael McDowell was 10th.
Tony Stewart, seeking his fifth victory in his final race at Daytona, was in contention until a late accident. He finished 26th.
Dale Earnhardt Jr. was the defending race winner, but never contended Saturday night and finished 21st. He was involved in the 22-car accident — his third consecutive crash in a plate race — but was able to continue to the finish this time.
"Miserable night," Earnhardt tweeted. "Had some gremlins in the steering."
