past both the McLaren and the Ferrari. Attrition kicked in as the race continued, with brakes in particular becoming a big issue. Fabi was the first brake-related retirement on lap 47, followed by Johansson on lap 49 and Prost on lap 54. Piquet's brakes also failed on lap 59, leaving Berger, Senna and Alboreto as the top three followed by Boutsen and Patrese. In the latter stages of the race Senna made a charge, closing to within eight seconds of Berger, before the Austrian pulled away again, setting the fastest lap of the race on lap 72. Berger crossed the finish line just under 35 seconds ahead of Senna, with Alboreto the only other driver on the lead lap and Boutsen, Jonathan Palmer in the second Tyrrell and Yannick Dalmas in the Larrousse completing the top six after Patrese suffered a late oil leak. In post-race scrutineering it was discovered that the brake ducts on Senna's Lotus were oversized, resulting in his disqualification from the race. Alboreto was duly promoted to second, giving Ferrari a 1-2 finish, with Boutsen third, Palmer fourth, Dalmas fifth and Roberto Moreno sixth, scoring the AGS team's first World Championship point. The only other classified finishers were Christian Danner in the Zakspeed, de Cesaris and Patrese. Dalmas did not receive the two points for his fifth place, as he was driving Larrousse's second car and the team had officially entered only one car for the championship. Race classification * Dalmas did not receive points towards the Drivers' Championship or the Jim Clark Trophy, as he was driving Larrousse-Lola's second car and the team had officially entered only one car for the entire championship.
