New Zealand's Scott Dixon has regained the Indycar championship lead after finishing third at Edmonton.
Dixon's three points clear of his Target team-mate Dario Franchitti, who's 11 clear of the Australian Ryan Briscoe.
The defending champion Dixon had been running second behind the Australian winner Will Power more for most of the 95 lap race , when Helio Castroneves squeezed past with 10 laps to go for a Team Pernske one-two .
Power was well clear on his way to his first in an Indycar race when Tomas Scheckter crashed with two laps to go and the race ended under caution with Briscoe fourth and Franchitti fifth.
