 Gordon's chance to win was soon greatly damaged when he missed Turn 10 and had to use the pitlane to rejoin the circuit.Because he clipped a wall in the incident, he suffered a puncture (just like in Toronto) and made an unscheduled green flag pit stop, dropping to 17th and handing the lead to Nigel Mansell.While Mansell established an 11-second lead, Michael Andretti passed Unser for 2nd place, recovering his position he lost in the early laps when he had a right rear puncture.
