TALLADEGA, Ala. -- Tony Stewart snapped his 43-race winless streak on Sunday at Talladega Superspeedway, getting the victory when NASCAR ruled Regan Smith drove below the yellow out-of-bounds line to get by Stewart on the final lap.

NASCAR decided Smith's move was illegal, and Stewart earned his first win of what's been a frustrating final season at Joe Gibbs Racing.

In making his first Sprint Cup Series trip to Victory Lane, Stewart crossed Talladega off the list of four active tracks where he'd failed to win a race. Stewart finished second a maddening six times before this win.
