DOVER, Del. - Ryan Newman overcame a flat tire that cost him two laps, then gambled on fuel and completed a sweep Sunday of the races at Dover International Speedway.

He went the final 106 laps without stopping to get his seventh win this season, benefiting from two late caution flags that slowed the field for 12 laps. Newman didn't have to race hard to get the first lap back because of NASCAR's new rule awarding a lap to the highest-scored car off the lead lap.

Although it worked out for him, Newman is opposed to the new rule.

''I just don't want to see guys get their lap back and not earn it,'' he said. ''Once we got our lap back it was just sort of a fuel mileage race.''

This was the first Winston Cup event in history in which racing back to the flag stand under caution was prohibited. NASCAR outlawed the practice after Dale Jarrett's wrecked car sat precariously in the middle of the track as others attempted to unlap themselves or improve their positions a week earlier in New Hampshire.

Newman regained the second lap by staying on the track on lap 328. Then, on old tires, he held off hard-charging Jeremy Mayfield, who harassed him for 10 laps until Newman opened a five-car-length lead with 15 laps to go.
