Helio Castroneves, who last month won the Indianapolis 500 for the third time, beat Penske teammate Ryan Briscoe off pit row on the final stop and held on for the final 46 laps to win at Texas Motor Speedway on Saturday. Briscoe was dominating the race, with more than a 10-second lead before a caution flag on the 150th of the 228 laps bunched the field. Castroneves worked past Marco Andretti after that restart and was on the tail of his teammate when A.J. Foyt IV crashed 15 laps later. When everybody went into the pits for the final time, Castroneves had a 6-second stop, beating Briscoe and Scott Dixon out by more than half a second. Castroneves' winning margin was 0.39 seconds. It was the 16th career victory for Castroneves. Australian Briscoe finished second for the second consecutive week, though took over the season points lead from Scott Dixon. Marco Andretti was fourth and polesitter Dario Franchitti, the Ganassi teammate of Dixon, finished fifth. Danica Patrick was sixth, ending her streak of four consecutive top
