de Silvestro tops opening practice at Indy
 |
| De Silvestro with team boss Michael Andretti |
Andretti Autosport Honda driver Simona de Silvestro turned a lap at 222.314 mph to lead the opening practice session for the 99th running of the Indy 500.
Sage Karam was the fastest Chevy in 2nd at 221.50 followed by four Hondas of James Jakes, Conor Daly, Gabby Chaves and Oriol Servia.
None of the drivers have their cars trimmed out this early in the first test of the speedway aero packages, so look for faster times as the month progresses.
