JOLIET, Ill. - Ryan Newman and an empty gastank spoiled Kevin Harvick's bid for three straight Chicagoland Speedway victories, with Newman pulling away at the end to win the Tropicana 400 on Sunday.

Newman and Harvick both pitted to top off their tanks on lap 198 of the 267-lap race, hoping to stretch the fuel to the end. Newman made it, and Harvick didn't.

Newman got out of the pits first and took the lead for good on lap 210 when the drivers ahead of him all pitted under caution. Harvick worked his way to second on lap 225 and was close behind when the green flag waved on lap 240 for a restart following the last of seven caution flags in the race.

Harvick, one of only four drivers who have won the first two races at a new track since NASCAR's modern era began in 1972, couldn't catch Newman's Penske Racing South Dodge.

Newman kept edging ahead, moving out to a lead of more than 1 second before Harvick's Richard Childress Racing Chevrolet suddenly slowed three laps from the end.

''He had a fast race car and I was really worried about him until he ran out of gas,'' Newman said. ''I got out there in the clean air and that was pretty much the biggest thing,'' Newman said.
