Senna made his pit stop three laps before Prost, enabling him to take the lead thanks to a slow stop for Prost with a sticking front wheel, but traffic on the Mistral Straight (including a less than helpful Piquet who most likely enjoyed seeing Senna lose the lead to Prost at close quarters) and a gearbox problem allowed Prost to close right up to him and then overtake him on lap 61 as they lapped Alex Caffi and Pierluigi Martini at the Signes corner. Meanwhile, Berger reclaimed third only for Alboreto to pass him again during the pit stops, while Mansell suffered his seventh consecutive retirement, dropping out on lap 49 with suspension problems, though he had been dropping back for a number of laps with power loss from his Judd V8 engine. After returning to the pits and getting himself cleaned up, the Englishman left the circuit profoundly fed up with the performance of the Williams, fuelling ongoing speculation in the press that he would leave the team at the end of the year to join Ferrari after the Italian team had announced they would not be keeping Alboreto for 1989. Despite the rumours turning out to be correct, Mansell continued to deny he was joining Ferrari.
