Italy’s Valentino Rossi won his second MotoGP race of the season in Argentina after world champion Marc Marquez crashed out in the closing stages.
Nine-time world champion Rossi overhauled Spaniard Marquez, with Italy’s Andrea Dovizioso taking second and Briton Cal Crutchlow third.
Marquez, struggling with his tyres, clipped Rossi’s back wheel when trying to regain the lead and went down.
Officials reviewed the incident but decided that no action was necessary.
“I am sorry about this, he touched me on the corner and I hope he is OK,” said Rossi.
“The bike was great and now two victories already. I think we will be able to fight to the end.”
Britain’s Danny Kent won the Moto3 race for the second week in a row, while compatriot Sam Lowes was third in the Moto2 race.
