FORT WORTH, Texas - Helio Castroneves dominated the Firestone 550 at Texas Motor Speedway to take sole possession of first place in the IZOD IndyCar Series championship standings through eight of 19 races.
Driving the Chevrolet-powered No. 3 AAA Insurance Team Penske car, Castroneves led 132 of 228 laps on the 1.5-mile, high-banked oval and won by 4.6919 seconds over reigning series champion Ryan Hunter-Reay in the No. 1 DHL car for Andretti Autosport.
"It was just the setup; we did a lot of homework. Awesome job everyone," said Castroneves, who broke a tie with Johnny Rutherford for 12th on the all-time Indy car list with his 28th victory.
Castroneves broke a tie with Marco Andretti, who led 57 laps early and placed fifth, to move 22 points clear heading to the Milwaukee IndyFest on June 15 at the Milwaukee Mile.
It was the first victory of the season for Team Penske and the sixth different team to hoist a trophy in Victory Circle.
"Helio drove a flawless race and a key victory in our season based on where we were in the standings," team owner Roger Penske said. "It probably was the best execution we've had in a long time. Helio now leads the points and that's critical as we are in this stretch of oval races."
Tony Kanaan, who started 13th in the No. 11 Sunoco "Turbo" car, finished third and Ed Carpenter posted his best finish of fourth at the track.
