WATKINS GLEN, New York (Ticker) -- After a week in which he feared losing his ride, was fined and disciplined by NASCAR, Tony Stewart this time channeled his anger into an impressive victory at the Sirius Satellite at the Glen on Sunday.

Stewart was fined $10,000 and put on probation by NASCAR on Tuesday for hitting a photographer last week in Indianapolis. Team sponsor The Home Depot also fined him an additional $50,000 for his conduct and Stewart was instructed to take anger-management classes to learn to control his temper.

Stewart led three times for 35 of the 90 laps and dedicated the victory to his team and Indianapolis Star freelance photographer Gary Mook, whom he punched after fading out of contention late in the Brickyard 400.

"I owe this all to my Home Depot team and that they stuck with me this week," said Stewart, who earned $165,303. "It's been a tough week for all of us. I've done a lot of things to hurt this race team. We've also done a lot of great things. It's nice to be able to come back and run like we did."

The 31-year-old driver regained the final lead from Ryan Newman with 19 laps remaining and overcame a red flag caution with three laps to run. Newman recorded his fifth consecutive top-five finish and tops all drivers in that category with 10.

"I just didn't get into Turn 10 real well," Newman said of Stewart's pass. "He got down under and just went by me for the lead."

Newman moved into the lead for the Rookie of the Year championship ahead of Jimmie Johnson, who was 16th.

NASCAR halted the race to clean the 2.45-mile Watkins Glen International course of debris caused by Kenny Wallace, who lost control of his Chevrolet in Turn 10 and spun across the gravel before slamming into the foam barriers. He was not injured.

Stewart tied Matt Kenseth with his series-best third win of this year and gave Pontiac Grand Prix its first triumph at the upstate New York track since Kyle Petty in 1992. It was Stewart's second road-course win and 15th career.

More importantly, Stewart also gained 104 points on Winston Cup leader Sterling Marlin, who lost a cylinder and hobled home 30th.

Robby Gordon was third for his fourth top-10 result in the last five races. He led 21 laps and made side contact with Stewart.

"Tony tried to drive by me and locked up his brakes and got into the side of me," Gordon said. "As far as what I did to Tony after the race, that was just a little love."

Gordon gave Stewart a little brush on the side following the checkered flag.

Road-course specialist P.J. Jones was fourth, giving A.J. Foyt Racing its top finish in Winston Cup in three years.

Pole sitter Ricky Rudd rounded the top five after leading just the first three laps.

Mark Martin was 10th to move back into second place in the standings, 53 points behind Marlin.

The race had seven cautions for 18 laps and nine drivers exchanged leads 12 times.
