FOUNTAIN, Colo. — Scott Dixon won the Honda Indy 225 under a yellow flag Sunday for his second IRL victory this season.
Dixon, who also won the IRL's season-opening race at Homestead, Fla., led 89 laps, including the final 84. Two cars spun out in the final 10 laps, producing two yellows.
Season points leader Tony Kanaan was runner-up for the second straight week, followed by Gil de Ferran, the race's defending champion.
Dario Franchitti, in his first race since breaking a vertebra in his lower back in a motorcycle accident April 4, was fourth. Sam Hornish Jr. took fifth, the highest finish for a Chevrolet engine this season.
Dixon, who led five laps after a flurry of pit stops early in the race, made an inside pass on de Ferran to take the lead again on the 142nd lap. Seven laps later, Kanaan passed de Ferran to move into second.
Dixon extended his lead over Kanaan to nearly 6 seconds before a yellow flag on the 215th lap after Dan Wheldon spun coming out of Turn 4.
The green light came back on on Lap 219, but one lap later Roger Yasukawa hit the wall in Turn 1, bringing out another yellow and depriving fans of a restart and another sprint to the finish, as happened last week at Texas Motor Speedway.
"It was a bit of a shame," said Dixon, a 22-year-old native of New Zealand. "It's always nice to have a race at the end."
Kanaan was unable to overtake Al Unser Jr. in last week's race.
"That's just racing," Kanaan said of the yellow. "It happens."
Kanaan, who started on the pole on the basis of having the fastest lap in the final practice session before qualifying was rained out, took the first-lap lead but relinquished it to Helio Castroneves on Lap 2.
Castroneves led for the next 46 laps, with teammate de Ferran second and Kanaan third.
De Ferran passed Castroneves in traffic on the 48th lap.
Fast-closing Tomas Scheckter moved into second place on the 63rd lap and then overtook de Ferran with an inside pass on the 77th lap.
Castroneves faded to seventh after getting high on the track and losing speed, and drivers soon began pitting.
Hornish, running in the top 10, ran out of fuel and coasted into the pits.
After a brief caution because of debris on the track, de Ferran moved back into the lead after Scheckter collided with Felipe Giaffone in the pits. Giaffone pulled out of his pit and tapped tires with the incoming Scheckter, who then was required to make another lap before pitting.
Scheckter would finish eighth.
Unser, who had slow practice times this week and started 20th in a 22-car field, wound up 14th.
