Scott Dixon, Ganassi, St Petersburg 2012Scott Dixon has conceded that he did not have the pace to fight Helio Castroneves for the victory in the closing stages of Sunday's IndyCar race in St. Petersburg.

The Target Chip Ganassi Racing driver, who finished second, lost the lead to Castroneves when the Brazilian drove around the outside of him at Turn 1 with 27 laps remaining. Once ahead, Castroneves quickly pulled out a gap that Dixon said that he simply could not close down.

"Helio was a man on a mission," he said. "I don't think we had the pace. [I was] probably a little too cautious on Turn 1 where he did go around the outside - I didn't push the envelope too much. I was trying to envision a finish here. So that's the way it went.

"He was rocketship fast, and kind of in a class of his own today. That was all we had."
