(INDIANAPOLIS, Ind.) -- Simon Pagenaud won his third career IndyCar race Saturday but took a back seat to the headlining story after a crash began the 2014 Grand Prix at Indianapolis. Pole-sitter Sebastian Saavedra's car failed to start to begin the inaugural event and two fellow drivers crashed directly into the back of him, setting off a violent chain reaction.
A standing start was used to commemorate the first-ever road race at the famed Indianapolis Motor Speedway. Saavedra's car stalled when the lights went out and was eventually struck by Carlos Munoz and again by Mikhail Aleshin.
"We just followed protocol," said Saavedra, who walked away from the wreck as did the other drivers involved. "As soon as I released the clutch, it went from 11,000 rpm to zero. This should not have happened, unfortunately."
All three drivers were treated on-site for minor injuries and cleared by IndyCar to participate in practice for the Indy 500 on May 25. Indianapolis Mayor Greg Ballard was the official race starter and suffered minor injuries when he was hit by debris. Ballard did not require stitches and was released by medics at the venue.
