Castroneves tops Carb Day practice

The Penske driver set his time of 40.1929 seconds on only his third lap and then remained unbeaten for the rest of the hour.

His team-mate Will Power completed a Penske one-two as he prepared for what could be his last IndyCar Series race of the year, with Ryan Briscoe emphasising Penske's pace in fifth place.

Mario Moraes impressed again in third place, and with his team-mates Townsend Bell and Paul Tracy taking ninth and 12th, KV Racing Technology looks in extremely good shape going into its second Indy 500.

Dan Wheldon suggested he will rapidly move forward from his 18th place on the grid by going fourth quickest for Panther Racing today, with Ganassi duo Dario Franchitti and Scott Dixon, and fourth-place qualifier Graham Rahal (Newman/Haas/Lanigan) completing the top eight.

Davey Hamilton set a promising 10th-fastest time in the best of Dreyer & Reinbold's four entries - but it was an underwhelming session for race's only other four-car squad, Andretti Green Racing, as its top runner Tony Kanaan was back in 11th.
