Team Penske took a 1-2-3 in Friday afternoon practice for Sunday's IZOD IndyCar Series race at Edmonton's airport track. Championship leader Will Power was in front for most of the session, followed by teammates Ryan Briscoe and Helio Castroneves.

The dominant Penske and Ganassi teams had filled the top five in the early running as well, until Dreyer & Reinbold's Justin Wilson got among them -- and then kept improving until he was within a few tenths of Power.

But Power had more speed in hand and improved to a 1m01.6689s lap, to secure the top spot ahead of Briscoe, Castroneves and Ganassi's Dario Franchitti, with Scott Dixon pushed back to sixth in Ganassi's other entry as rookie Takuma Sato made a spectacular last-gasp run to grab fifth for KV Racing Technolgy.

KV had three cars in the top 10 again -- EJ Viso and Paul Tracy were eighth and ninth, followed by Tony Kanaan (Andretti Autosport).

The session saw three brief stoppages for yellows, caused by Bertrand Baguette crashing his Conquest car, Milka Duno (Dale Coyne) spinning and stalling, and Tomas Scheckter sliding into a tire wall.
