Driver-owner Ed Carpenter, now driving only on ovals, won the IndyCar Series race Texas on Saturday night after staying in front of Will Power during a two-lap shootout after a late caution.

On the final green-flag stop with 35 laps left, Carpenter beat polesitter and season points leader Power off pit road. Team Penske driver Power made things worse when he was penalized for speeding out of the pits.

Power was sixth, and Carpenter had a lead of about 18 seconds over Juan Pablo Montoya, when Takuma Sato's engine blew and his car caught fire with 10 laps left.

While the top four cars stayed out during that caution, Power went in for fresh tires. He then made a charge after the final restart to finish second.
