Stewart earned the pole since qualifying at Pocono was cancelled due to rain on Friday, but had to start last in a backup car after wrecking in Saturday's practice. He beat Carl Edwards out of the pits by a little more than a car length and then captured the lead with 37 laps remaining. "Smoke" drove the final 102.5 miles without refueling his No.14 Chevrolet to become the first driver/owner to win a Cup race since Ricky Rudd did it in September 1998 at Martinsville.

"(Crew chief) Darian Grubb was giving me the intervals and just kept me running the pace he wanted me to run," Stewart said. "We're just thankful we could make it."

Stewart collected his 34th career victory. He won at Pocono for the second time, with his first victory come here in June 2003.

The two-time Cup Series champion also became the fourth driver to start from the back of the field and win this year. He joined Matt Kenseth (Daytona), Kyle Busch (Las Vegas) and Brad Keselowski (Talladega).

Edwards, who led the most laps with 103, finished second. He too gambled on fuel in the closing laps.

"I'll probably be happy later today, but right now, to be that close to victory and to not win, that is frustrating," Edwards said.

Edwards led the series with nine wins in 2008, but has yet to record a victory this year.

Midway through the 200-lap race, Edwards had to pit for fuel earlier than expected after his crew did not fill the car with enough gas on his previous stop. He benefited from a caution shortly after when the leaders came on to pit road.

David Reutimann finished third, followed by Jeff Gordon and Stewart's teammate Ryan Newman.

Marcos Ambrose was sixth, while Jimmie Johnson coasted home in seventh after running out of fuel on the final turn of the last lap.

"At the end, we were just playing a fuel game, and I didn't play it well," Johnson said.

Johnson overcame a penalty for pitting too early during a caution, which forced him to the back of the lead lap at the half-way point.

Juan Pablo Montoya, Jeff Burton and Sam Hornish Jr. completed the top-10.

Stewart won the all-star race, a non-points paying event, last month at Charlotte.

"It was nice to get that all-star win this year, but it was nice to get that first point win too," he said. "It's nice to extent the point lead."

Stewart's lead is now 71 points over Gordon and 103 ahead of Johnson.

Denny Hamlin finished 38th and dropped to 12th in points, while Mark Martin fell to 13th, just two points behind Hamlin, after a 19th-place run.

Hamlin's car lost power and stalled on the track in the opening laps, forcing the first caution and then setting up a double-file restart, a new rule NASCAR implemented last week.

Dale Earnhardt Jr. lacked grip on the track throughout the day and ended up finishing 27th in his second race with crew chief Lance McGrew. Earnhardt also made slight contact with David Stremme, sending Stremme into the wall on lap 112.
