DOVER, Del. - A penalty to Jimmie Johnson was all Tony Stewart needed to break out of a four-month slump.
After Johnson was assessed a drive-through penalty for jumping the final restart - a sanction Johnson protested vehmently - Stewart passed Juan Pablo Montoya on Lap 398 of 400 to win Sunday's FedEx 400 benefiting Autism Speaks at Dover International Speedway.
The victory was the first of the season and third at Dover for Stewart, who has notched 42 of his 48 career wins after May 31. Stewart finished .788 seconds ahead of Montoya, who matched his career-best NASCAR Sprint Cup Series finish on an oval track.
Jeff Gordon came home third, followed by Kyle Busch and reigning Cup champion Brad Keselowski. Johnson finished 17th, the first car one lap down, smarting from a penalty he felt was unjustified.
