In one of the most dramatic moments in Indy 500 history, Danny Sullivan took the lead from Mario Andretti on lap 120. But as he was completing the pass, Sullivan's car stepped out, and he lost control. He spun directly in front of Andretti in turn one, doing a complete 360°. Andretti veered to the inside and slipped by unscathed, while Sullivan's car somehow avoided contact with the concrete wall. Sullivan remarkably gathered control without stalling the engine, and continued in the race. About twenty laps later, Sullivan managed to re-pass Andretti for the lead, this time cleanly. Sullivan led the final 61 laps, and scored his first and only Indy victory. It was the fifth Indy win for car owner Roger Penske (Penske Racing), tying the record at the time held by Lou Moore.
