For 1989, de Cesaris moved to the Marlboro-sponsored Scuderia Italia squad. Early results were again promising. By now one of the more experienced drivers in the field, de Cesaris was on course for a podium position in Monte Carlo, before being taken out by triple world champion Nelson Piquet at the Lowes Hairpin. De Cesaris lost his temper after the accident and berated Piquet's Lotus team upon returning to the pits. Two races later, after an early delay, he was being lapped by Dallara teammate Alex Caffi when he ran his fellow Italian into the wall, robbing his team of a potential podium. De Cesaris finished third at the next race in Canada, behind Williams drivers Thierry Boutsen and Riccardo Patrese in a rain-soaked race. The race would be the last time de Cesaris stood on the Formula One podium.
