Busch dominates on way to win at Pocono

LONG POND, Pa. (AP) — Kurt Busch made it a clean sweep for Roush Racing at Pocono.

With veterans Rusty Wallace and Mark Martin trying desperately for one last shot at glory on the mountaintop, Busch spoiled the going away party and kept moving toward another Nextel Cup title.

Busch dominated each end of the Pennsylvania 500 on Sunday and raced to his second win of the season, joining teammate Carl Edwards as winners for owner Jack Roush this year at Pocono Raceway.

‘‘This is Pocono perfection for Jack this year and for us to dominate today, it’s just a tribute to what the crew is doing for me — and that’s building great race cars,’’ said Busch, who earned his 13th career victory.

Busch is also building a case for a second straight NASCAR Nextel Cup championship. He remained steady in fifth place in the points race, 262 behind leader Jimmie Johnson.

With only six races left to determine who qualifies for the ‘‘Chase for the Cup,’’ there’s little room for error. Dale Jarrett holds the 10th — and probably final — spot over Jamie McMurray (nine points back) and Carl Edwards (12 points behind).

The ‘‘Chase for the Cup’’ begins at New Hampshire International Speedway on Sept. 18.

‘‘I got out of the car and said, ’I think I can still do this,’’’ Wallace said.

Wallace, a four-time winner at Pocono who is retiring, was second in his final race at the 2.5-mile triangle track. Perhaps driving his last race at Pocono, Martin finished third in the No. 6 Ford. Carl Edwards followed his win here in June with a fourth-place finish.

While Wallace is firm in his commitment to retire, Martin may have his farewell tour extended another year because Roush is without a driver for the No. 6 Ford next year.
