Scott Dixon won his second IZOD IndyCar Series race at the Edmonton City Centre Airport on Sunday, though it did not come without its share of controversy.
Helio Castroneves was assessed a non-appealing penalty for blocking Team Penske teammate Will Power on the 93rd lap of the 95-circuit Honda Edmonton Indy.
He refused to head into the pits for his drive-thru penalty, and dropped to 10th place in the official results after being assessed a 20-second penalty to his time.
An angry Castroneves confronted three race officials after climbing from the car, grabbing one by the collar, but it was no use. It was the second time in three years that a blocking penalty on Castroneves took a race win from him. The other instance occurred at Belle Isle in 2008, where Justin Wilson eventually took the victory.
So Dixon and Power, the past two winners of the event, stood 1-2 on the podium at the end, with Dixon's Chip Ganassi Racing teammate, Dario Franchitti, placing third.
It was Ganassi's second victory of the day. The other came with driver Jamie McMurray in NASCAR's Brickyard 400, held at IndyCar mecca Indianapolis Motor Speedway. Ryan Briscoe and Ryan Hunter-Reay rounded out the top five.
The two biggest surprises in qualifying, E.J. Viso (sixth) and Simona de Silvestro (seventh), had wildly divergent days. Viso was unable to maintain his position directly behind the sport's top two teams, but rebounded to finish eighth, as KV Racing Technology cars swept positions six through nine.
Meanwhile, de Silvestro ran strongly for much of the race, a necessary boost for HVM Racing, but finished a disappointing 22nd after her fuel pump broke with eight laps to go.
And finally, critics of Milka Duno may see some relief, as she was put on probation for the rest of the year during the race weekend. Series officials have cited her failure to meet minimum standards of performance, such as maintaining 107% of the leader's speed, and poor decision-making on the track (to the ire of many of her competitors).
