Rossi dominates first practice at Road America IndyCar race.

Alexander Rossi topped the 27-car field in the first practice session of the NTT IndyCar Series at Road America with a best lap of 1m41.7790s. David Malukas and Alex Palou followed in second and third place, respectively. The newly-paved track and Firestone's new tires produced impressive speeds, with Rossi knocking more than three seconds off his most impressive lap prior to the repave. The session provided an opportunity for teams to understand the differences between the tires used last week and the new Firestone Reds.
