Behind the McLarens, Piquet was maintaining third ahead of the Williams pair of Patrese and Mansell. The Italian opened a small gap on his teammate and closed on Piquet, making several attempts to pass the Brazilian. However, he spun on lap 53, letting Mansell past. The Englishman was no more successful in trying to pass Piquet, and he retired on lap 66 when his brakes failed and he spun into the wall. By lap 59 Prost was putting in a succession of fast laps, extending his lead to over 30 seconds and lapping the whole field up to the fifth-placed Rial of Andrea de Cesaris.
