Edmonton, Canada (My Sportsbook) - Will Power became a first-time winner in the IndyCar Series with a dominating performance in Sunday's Rexall Edmonton Indy at Edmonton City Centre Airport circuit.

Power started on the pole and led 90 of 95 laps, relinquishing the top position only when he pitted. He held a one-second lead over his Team Penske teammate Helio Castroneves before the race ended under caution for an incident involving Tomas Scheckter with less than two laps to go.

"The first stint was really tough, but then I relaxed, and it felt very good at the end," Power said. "The car was really good all the time."

Power joined Penske at the beginning of the year as a test driver and fill-in for Castroneves while he was on trial for federal income tax evasion charges. When Castroneves was acquitted and returned to racing in April at Long Beach, CA, Power moved from the No.3 car to a third Penske entry (No.12). He finished second at Long Beach.

Last week, Power finished third on the streets of Toronto - his first start since a fifth-place run in the May 24 Indianapolis 500.

Power's first IndyCar win came in his 21st start. He has finished no worse than sixth so far this year.

"Everything has gone so well this year, and I'm really glad to be a part of this team," he added.

Castroneves' runner-up position gave Penske a one-two finish for the second time this season, with the first coming last month at Texas, as Castroneves captured the victory and Ryan Briscoe came in second.

"(Will) did a hell of a job today, and I'm happy for him," Castroneves said. "It was a big battle out there. It was very hard and tough, and towards the end, I was pushing as hard as I could."

Scott Dixon from Chip Ganassi Racing came in third, while Briscoe was fourth. Dixon, the defending series champion and last year's winner at Edmonton, took a three-point lead over his teammate Dario Franchitti, who finished fifth.

"It was a tough race, but I think lap traffic played to our advantage," Dixon said. "The last part of the stint I was really trying to hold on."

Paul Tracy, Graham Rahal, Justin Wilson, Robert Doornbos and Marco Andretti were sixth through 10th, respectively. Danica Patrick finished 11th.

The 95-lap event featured a horrifying moment during a round of pit stops in the early going when the ethanol fuel pump filling Tony Kanaan's car remained opened after his stop, soaking the Andretti Green Racing driver.

As Kanaan exited his pit stall, the fuel ignited with Kanaan scrambling to escape from his car. Crew members from Penske and Panther Racing quickly extinguished the flames.

Kanaan suffered burns on his thumbs and face. He will be re-evaluated by Indy Racing League medical officials later this week before the series heads to Kentucky Speedway.

"I felt the spray, and I knew it was fuel," Kanaan said. "At that point, I wanted to get out of my pit so I wouldn't get my guys burned, and then I closed my eyes and held my breath as I tried to get out."

Kanaan ended up finishing 21st.
