As the rain began to fall yet again the Williams pitted for wet tyres, with Senna staying out on dry tyres. Senna's decision proved correct as the track began to dry quickly. Prost suffered a problem in the pits when the Williams pitted for dry tyres. This pushed him down into fourth position, a full lap behind Senna. As it began to rain for the fourth time, Barrichello pitted, losing his second-place position to Hill. Barrichello quickly retired due to fuel pressure problems. Senna won the race (by over one minute) with Hill in second and Prost in third.
