Roger Penske won't reveal motive for bringing Allmendinger to IndyCar finale

Roger Penske, needing nothing short of a miracle for Helio Castroneves to win the IndyCar title in next week's season finale, will run a third car for AJ Allmendinger in what's presumed to be a strategic move to aid their championship chances.

But if the plan is for Allmendinger to try to snatch points away from championship leader Scott Dixon, Penske wouldn't show his hand.

The team owner insisted Allmendinger will run the No. 2 car at Auto Club Speedway in Fontana, Calif., next Saturday night as a farewell to sponsor Izod.

IndyCar said last month Izod would not return as title sponsor of the series next season. Izod is also a Penske sponsor and was on Allmendinger's car in two of the five IndyCar races he ran this season.
