It was the third Grand Prix victory for Alboreto, who also became the first Italian driver to win for Ferrari since Ludovico Scarfiotti at the 1966 Italian Grand Prix. British driver Derek Warwick finished second in a Renault, some 42 seconds behind, with Alboreto's French teammate René Arnoux third.
Goodyear dominated qualifying filling six of the top seven places with Michele Alboreto securing his first career pole position. Ferrari Teammate René Arnoux was second, followed by Keke Rosberg in the Williams FW09-Honda. 
Alboreto led all 70 laps and was even able to retain the lead during pit stops, despite Piquet pushing through without stopping. 
Piquet found himself third after the stops, but faded as the race neared its conclusion. Arnoux moved into third until he was caught by Rosberg. Piquet's BMW engine blew and with a lap to go and Rosberg ran out of fuel, allowing Arnoux to join Alboreto and Warwick on the podium. Rosberg was classified fourth, with de Angelis fifth and Stefan Bellof completing the top six in his Tyrrell 012-Ford.
