Auto racing: Brian Vickers survives a fuel duel against Jimmie Johnson for Sprint Cup victory

Brian Vickers saved enough fuel to win in Michigan.

Closing in on the checkered flag with mostly fumes in his gas tank, there were only two possibilities for Brian Vickers.

BROOKLYN, Mich. — Closing in on the checkered flag with mostly fumes in his gas tank, there were only two possibilities for Brian Vickers.

Run out of gas and probably blow any chance at making NASCAR's championship chase — or make a bold move toward title contention by winning the race.

After a surprising gamble on gas by his crew chief, Vickers drove conservatively to conserve fuel. Then he pounced when race leader Jimmie Johnson's tank ran dry, taking the lead with two laps to go and holding on to win Sunday's Sprint Cup race at Michigan International Speedway.

Vickers had confidence in crew chief Ryan Pemberton, but he also had a sick feeling in his stomach during the last few laps.

"I've got to tell you, when you're coming to two to go, I'm still sweating bullets, no matter how much confidence you've got," Vickers said.

Vickers won his second career race, boosted his chances of making the chase and delivered the first checkered flag for Red Bull Racing.

It was the second time in two races at Michigan this season that Johnson's crew gambled on gas and lost. Johnson also was in the lead when he ran out of fuel in June, handing a win to Mark Martin.

"Certainly frustrated," said Johnson, who was 33rd. "We've won one race on fuel mileage ever. It's just what we're not good at. I think it's a little too risky for us to even try it."

Jeff Gordon finished second, followed by Dale Earnhardt Jr., Carl Edwards and Sam Hornish Jr. Series points leader Tony Stewart, who clinched his spot in the chase by starting Sunday's race, finished 17th.

Enumclaw's Kasey Kahne was 11th and Greg Biffle of Vancouver, Wash., was 20th.

With three races left before the cutoff for NASCAR's season-ending championship chase, the win provided a significant boost to Vickers' chances of qualifying. Vickers jumped one spot in the standings to 13th, and is only 12 points behind Martin for the 12th and final chase qualifying spot.

Martin apparently ran out of gas on the final lap and finished 31st.

It also was the continuation of a wild weekend for Vickers, who won the pole Friday and then spent Saturday sparring with Kyle Busch.

Vickers and Busch both are trying to climb into the top 12 in Sprint Cup points to qualify for the chase, and their rivalry ratcheted up during Saturday's Nationwide race when they raced for the lead on the final lap and both were passed for the win by Brad Keselowski.

They exchanged words afterward, a confrontation Vickers called "ridiculous" and "unnecessary" Sunday night.
