Jason Line raced to his fourth Pro Stock victory of the season Sunday in the Torco Racing Fuels NHRA Nationals to move closer to securing his first NHRA POWERade world championship title.

Cory McClenathan and Eric Medlen also won their divisions in the $1.6-million competition at Virginia Motorsports Park, the 21st of 23 events in the series.

Line, who set a U.S. performance record of 6.558 seconds during the weekend and scored the single race maximum of 138 points, leads teammate Greg Anderson by 119 points. In the final, the former NASCAR dyno operator drove his Pontiac GTO to a 6.597 at 208.42 to hold off Tom Martino, 6.645 at 207.78 also in a GTO.

``This is such a huge, huge step toward the championship,'' said Line, who can clinch the title if he scores 20 more points than Anderson in the ACDelco Las Vegas NHRA Nationals on Oct. 26-29. ``It was tough to race Greg in the semifinals because we all knew what was on the line, but we just raced like we have all year: straight up.

``This whole team is special, from the guys at the track to the guys at the shop. It's good that no matter what, the championship is staying with us.''

McClenathan powered his Top Fuel dragster to his 29th career victory and fourth at VMP with a final-round performance of 4.644 seconds at 304.74 miles an hour. He held off Rod Fuller, whose dragster lost traction at the start.

Medlen earned his second Funny Car victory of the season and sixth of his career, defeating Cruz Pedregon in the final. Medlen's Ford Mustang posted a 4.814 at 301.00, while Pedregon's Chevy Monte Carlo ran 4.873 at 297.02.
