Marc Marquez took victory at the San Marino Grand Prix, whilst Jorge Lorenzo crashed to enable Valentino Rossi to extend his championship lead to 23 points. The conditions wreaked havoc with the riders, with many who started on slicks changing to wet tyres, before changing back to finish back on slicks. Bradley Smith finished second, despite not pitting at all during the race, with Scott Redding remarkably completed the podium, even though he crashed early on.
Title leader Rossi had lead the race, but decided to ditch the wet tyres later than his rivals. Marquez and Lorenzo pitted two laps before the Italian, giving them the advantage. However Marquez was gifted the victory with six laps to go as Lorenzo came off.
Loris Baz finished fourth, with Rossi fifth and Danilo Petrucci sixth. Dani Pedrosa could only finish ninth after missing his pit board four times, with the Britain’s other rider Cal Crutchlow eleventh.
Rossi now leads the championship by 23 points, with reigning champion Marquez a further 40 points behind. Johann Zarco took yet another Moto2 win, and Enea Bastianini took the victory in Moto3, with Danny Kent finishing sixth.
