radioed Senna to slow down to ensure a safe 1-2 finish, allowing Prost to gain six seconds. On lap 67, Senna lost concentration at Portier, causing him to spin his McLaren into the barrier and damage the car's front suspension. Immediately afterwards, he went to his home in Monaco to contemplate losing a race that he had dominated from the first time he took to the track for free practice on Thursday morning; the McLaren team did not even hear from him until that evening, when he walked into the pits as they were packing up. Prost thus took his fourth Monaco win in five years, with Berger some 20 seconds behind and Alboreto a further 21 seconds back. Warwick finished fourth after a race-long battle with Palmer, while Patrese recovered from his collision with Alliot to take the final point, passing the other Lola of Yannick Dalmas on the last lap. Patrese's point was also the first-ever World Championship point scored by a Judd-powered car and his first point for Williams.
