of Gerhard Berger in the Ferrari, though late in the race he was hampered by a down on power engine thanks to a cracked exhaust on his car, and rounding out the points was his teammate Alessandro Nannini. Nannini had been fighting for 3rd place with Piquet, but despite being consistently quicker in the corners, he had to yield to superior Honda power on the straights. Piquet and Nannini banged wheels at the Tosa hairpin, and a couple of laps later the Italian lost 4th place to his teammate after another wheel banging dual with the reigning World Champion caused him to spin at Tosa. Nannini dropped to 7th with Boutsen, delayed 2 seconds by Nannini's spin, now charging after Piquet. A fired up Nannini then put in the fastest atmospheric lap in a climb back into the points and 5th place. Nannini had to settle for 6th though after being passed on the last lap at the Acqua Minerale chicane by a grass-cutting Gerhard Berger, now charging thanks to being lapped and having to drive one less lap on fuel. Some were surprised that Berger wasn't penalised for the move and while Ferrari team boss Cesare Fiorio claimed it was necessary for Berger to avoid a crash with Nannini, television replays suggested otherwise. Both Senna and Prost recorded a fastest race lap faster than Nelson Piquet's qualifying time and both McLaren drivers had lapped the entire field up to and including Piquet in 3rd place by lap 56 of the 60 lap race. That was actually good news for Piquet and Berger in their turbo powered cars against the atmospheric Benettons as it meant they had to do one less race lap on their allowed fuel and could push harder for the final three laps of the race. Prost's second place earned him 6 points which saw him surpass his and McLaren teammate Niki Lauda as the all-time career points leader, with 421.5 to Lauda's 420.5 points. In what had become standard practice at McLaren since Prost's disqualification for being 2 kg underweight at the 1985 San Marino Grand Prix, both McLarens stopped within metres of taking the chequered flag. Prost had started the last lap some 7 seconds behind his teammate but was only 2.334 behind at the flag as Senna had driven only as fast as he needed to both win and conserve fuel at what was
