Nannini exited the train when he pulled in to change tyres. This promoted Mansell to 7th, which he quickly turned into 5th by passing Boutsen and Caffi in quick succession. He then set about closing the 17-second gap to the leaders, and was promoted to 4th when Berger pitted for tyres. Having caught up to the leading group, Mansell passed Prost for 3rd. Patrese's Williams then began to develop a problem with a holed radiator, which slowed him and bunched up the leading group. Eventually, Patrese's holed radiator became so bad that both Senna and Mansell were able to pass him in the space of a few corners. Patrese retired from the race shortly afterwards.
