Auto racing | Sprint Cup star Stewart makes himself at home in Nationwide

LOUDON, N.H. — Tony Stewart isn't running many races in the NASCAR Nationwide Series this series, so he's making the ones he does drive in count.

The two-time Sprint Cup champion, who hasn't been having much luck and has no wins in the top stock-car series this season, drove away Saturday with the Camping World RV Sales 200, his fifth victory in seven Nationwide starts in 2008.

Stewart got good track position, restarting third after taking just two tires during his final pit stop on Lap 129 of the 200-lap event at New Hampshire Motor Speedway. He took the lead on lap 136 from fellow Cup star Carl Edwards on lap 136 and led the rest of the way.

Teammates Denny Hamlin and Kyle Busch finished second and third.

Greg Biffle of Vancouver, Wash., was 19th, and Spanaway's Derrike Cope was 30th.

The No. 20 Joe Gibbs Racing Toyota that Stewart drove has won eight of 17 races this season, including all five by Stewart and one each by Hamlin, Busch and heralded rookie Joey Logano. Busch also has two wins in his No. 18 entry and another in the Braun Racing car already this season.

Crew chief Dave Rogers made the two-tire call that Stewart credited with putting him in position to win.

"I look up and they're all coming," Rogers said of the last pit stop for the leaders. "It was a parking lot and I knew if we got back in traffic, we would never make it to the front."

The race ended under caution after Greg Biffle, racing side-by-side with Brad Keselowski for 10th place, appeared to touch the track apron and lose control, sliding hard into the outside wall.
