All of the crew members who work on Clint Bowyer's No. 15 team know they'll be out of a job in 12 more races. Like everyone else at Michael Waltrip Racing, they face an uncertain future in NASCAR following this week's announcement that the organization will close at the end of the season.

Bowyer insisted that wouldn't stop his No. 15 team from trying to win the championship.

It was a noble claim from the driver, who will likely be just fine and move on to another job in 2016. But there was no quit in the team Saturday night, though, as Bowyer grabbed a fifth-place finish at Bristol (Tenn.) Motor Speedway to remain in contention for NASCAR's playoffs.

"We desperately needed a solid run," Bowyer said. "Obviously, you're hungry for a win with this organization. It's fun to be a part of a group that can answer the call when you've got to dig down and reach down and get a little bit more to get in that Chase and be a part of an elite group.

"These guys are up for the challenge."

Bowyer is 15th in the Sprint Cup standings with two races remaining to set the Chase for the Championship field. He's holding the final transfer spot into the 16-driver field, and his finish Saturday night gave him a 35-point advantage over Aric Almirola.

It was a small victory for MWR, which learned Wednesday that co-owner Rob Kauffman had no plans to field cars in 2016. Bowyer was released from his contract, which still had two seasons remaining, and decided he didn't want to follow Kauffman to Chip Ganassi Racing.

It makes for an unsettling atmosphere at a time when Bowyer and his No. 15 team need to be nearly flawless.

Bowyer has little doubt they can stay focused and get him in the Chase. He noted that his team has been performing well for the last five weeks — four finishes of eighth or better, and he was inside the top-10 before he wrecked at Michigan — and the group understands the stakes.

"Let's face it, the last month these guys have answered the call and are really digging down deep and finding that extra something that you have to find for a championship-caliber team to compete and be a part of that Chase," Bowyer said.

Formula One

Lewis Hamilton won the Belgian Grand Prix from pole in Spa-Francorchamps, holding off Mercedes teammate Nico Rosberg and padding his lead in the Formula One championship standings.

The defending champion was two seconds ahead at the finish line for his sixth victory of the season in 11 races.

"An amazing weekend," Hamilton said. "I had great pace in the car. I was cautious at the end because of tires but I brought it home."

Hamilton's 80th podium pulled him level with the late F1 ace Ayrton Senna in fourth on the all-time list. Rosberg has 36, level with two-time champion Graham Hill.

Rosberg had a poor start and dropped from second to fourth before regaining the second position.

"I completely messed up the start," Rosberg said. "I tried everything but Lewis knew how to react."

Rosberg was in a rush to leave the circuit since his wife is expecting their first child "any time."

Hamilton's 39th career victory gave him a 28-point lead over Rosberg in the drivers' standings, with eight races remaining.

Romain Grosjean drove his Lotus to third place.
