IndyCar conducts overnight track work to prevent further Indy pitlane spins

In the morning session, 2016 Indy winner Alexander Rossi spun his Andretti Autosport machine as he straightened up on the warm-up lane beside the short chute between Turns 1 and 2.

Then, in the afternoon running, four-time 500 winner Helio Castroneves lost control of his Meyer Shank Racing car on the warm-up lane and spun across the grass and hard into the outside wall at Turn 2.
