After his victory in Sunday's Edmonton Indy, Helio Castroneves acknowledged a feeling of redemption for his loss by penalty on the airport circuit in 2010.

Castroneves had been the runner-up in three of the past four Edmonton races, and was leading late in the 2010 contest when he incurred a penalty for blocking. Scott Dixon went on to win that race. The degree to which that still stings the Brazilian when he was asked if this win took away from his anger about 2010.

“Take away? I don't think so. I think people remember that. Maybe some people would disagree with me, that's not my second win.

“We have to turn the page. I'm never going to forget what happened, but I've certainly got to move on. Today was a great day, so we finally can say we won here.”

Teammate Will Power, who surged from 17th to third place, said he thought Castroneves's win was a bit of racing karma.

“It's funny. In this sport, or life in general, what goes around comes around. You generally get what you deserve,” said Power. “He was right there last year, almost won it. He won it this year. So, you know, when something unjust happens to you, usually something comes back to replace that or make up for it. That's what I understand. It's the same as you do something bad to someone on the track, you know something is coming for you…”

Castroneves' 0.8sec triumph over Rahal Letterman Lanigan's Takuma Sato continued the domination of Team Penske in Edmonton. The team has won three of the five races at the track since the Champ Car/IRL merger.

Castroneves also moved past Power into second place in the standings with his win, and is 23 points behind Ryan Hunter-Reay, who finished seventh at Edmonton. Power admitted he is impressed with his teammate's turnaround in form.

Yeah, he's stronger than ever this year,” the Australian said of Castroneves. “He's been really consistent on days that he can't win. When he can win, he absolutely executes.

“If you go back a couple years, you understand he's always a guy in contention for a championship. To me it's not a surprise. He's definitely worked on driving details, adopted some of what I do, and I take some of what he does. So collectively we're faster.

“What I was impressed with this year, he actually switched to be a left-foot braker, which might have helped him, actually. That's pretty impressive because that's hard to do.”

Power is just three points behind Castroneves in third with four races to go. Mid-Ohio is next up in two weeks.
