Formula 1 - 1989 - Round 03 - Monaco GP

The first start was aborted when Patrese stalled his Williams. At the second start, for which Patrese was relegated to the back of the grid, Senna was first into Sainte-Dévote and Prost could do nothing but slot behind him. The McLarens proceeded to pull away from the field, while behind them Williams were in all sorts of trouble, as both Boutsen and Patrese had to stop for new rear wings. Nigel Mansell went out on lap 20 with more gearbox issues for Ferrari and one of the talking points of the race came on lap 33 when de Cesaris attempted to pass Nelson Piquet at Loews Hairpin. The predictable accident occurred and some choice words were exchanged between the two drivers (while still in their respective cars) and a huge traffic jam was caused. Brundle was looking good until he had to stop for a new battery and dropped back to seventh.

Senna continued to dominate the race while Prost, having been slowed by the Piquet-de Cesaris incident (he lost over 20 seconds to Senna in one lap having to wait for clear road to get moving again), could not recover and finished second behind his team mate. He was also held up for many laps trying to lap the Ligier of former Renault team mate René Arnoux who ignored both his mirrors and the blue flags prompting BBC commentator James Hunt to describe Arnoux's explanation of why he was so slow as "Bullshit" on live television. It was Senna's second win at Monaco and he did it the hard way, his McLaren losing first and second gear later in the race and disguising it to his best so Prost wouldn't react and push for the lead. Modena benefited from Brundle's stop and finished third, scoring his first points in Formula One and Brabham's last podium finish. Alex Caffi, Michele Alboreto, and Brundle, who was promoted to sixth on the final lap as a result of the retirement of Ivan Capelli, completed the point scoring positions. Caffi achieved both his and Dallara's first points.
