Qualifying times: Firestone Indy 225.

Helio Castroneves and Sam Hornish Jr appear determined to give their team boss Roger Penske something to remember in the last race at the track he built. The two Marlboro Penske runners secured the front row of the grid for Sunday's Firestone Indy 225, the 100th Indy Racing League event and the last at Nazareth Speedway which shuts its doors at the end of the year. Castroneves won this race by less than two tenths of a second last year from Hornish, who then was driving for Panther Racing.

Championship leader Tony Kanaan will line up third, with his on-form Andretti-Green Racing team-mate Dario Franchitti alongside. Franchitti won last week at Pikes Peak and enjoys the short tracks. Seemingly out of form after a very strong mid-season is the Rahal-Letterman team - Kanaan's closest title challenger Buddy Rice starts 10th, a place behind his team-mate Vitor Meira.

The Firestone Indy 225 is due to take the green flag at around 2pm Eastern Time on Sunday, that's 7pm in the UK. Check back to Crash.net for a full race report and results.
