Sonoma, Calif. ? A late-race collision between teammates Dario Franchitti and Marco Andretti on Sunday at Infineon Raceway left both drivers fuming and gave Scott Dixon a victory and a narrow lead in the IndyCar Series championship with two races remaining.

Although Franchitti refused to openly criticize his 20-year-old Andretti Green Racing teammate, he said, “Marco was out there trying to win the race, and we were out there trying to win a championship.

“A case, I guess, you know, he had his priorities, I had mine. I’d really like to look at the accident, talk to him before, you know, making further comment on it.”

Franchitti, who came into the race with an eight-point lead over Dixon in the championship, started from the pole and dominated the Motorola Indy 300, leading 62 of the 80 laps on the 2.26-mile, 14-turn road course.

Dixon, the 2003 series champion, stretched his fuel more than the other leaders almost all day and came off pit road just ahead of Franchitti on lap 68. With cold tires, the New Zealander had to yield to Franchitti heading into turn one, but did hold off another Andretti Green driver, Tony Kanaan, for second place at that point.

Andretti was the last of the leaders to pit, and he also came out just ahead of Franchitti on lap 69. But, unlike the veteran Dixon, last year’s top rookie tried to hold off Franchitti, and the two banged together, with the son of team co-owner Michael Andretti spinning out and Franchitti’s car sustaining damage to the front wing and suspension.

The incident brought out the first full-course caution flag of the day and, after the restart on lap 72, Dixon and Helio Castroneves, who already had passed Kanaan, both easily drove past Franchitti, struggling with the handling of his damaged car.

“We’re teammates, and we look after each other, and that shouldn’t happen,” Franchitti said of the contact with Andretti.

The younger Andretti wasn’t as tactful after a quick visit to the infield medical center.

“I gave racing room, and I was hoping he would race me clean,” said Andretti, whose only IndyCar victory came on the Sonoma road course last year. “I hate to think he’d do anything intentional.”

There was one more caution flag for a collision between Scott Sharp and A.J. Foyt IV, but the race finished under green with Dixon holding off Castroneves to take a four-point lead over Franchitti heading into next week’s race at Belle Isle in Detroit.

Sam Hornish Jr. finished fifth, followed by Danica Patrick.
