It was Dovizioso’s third win this season and the 11th of his MotoGP career.
Lorenzo was in a tight battle with Marquez for second until he fell with two laps to go. That handed second to Marquez, while Cal Crutchlow finished third.
Lorenzo got back on his bike and finished 17th.
Marquez now leads Dovizioso by 67 points, while Valentino Rossi — who finished seventh — dropped from second to third in the standings, 70 points behind.
Francesco Bagnaia won the Moto2 race and Lorenzo Dalla Porta won the Moto3 race at the Misano World Circuit Marco Simoncelli.
