Marc Márquez finished 13th on his return to the circuits after recovering from surgery and missing the last six races of the championship
Francesco Bagnaia, in top form, took pole to lead Ducati's dominance in qualifying for the Aragon Grand Prix. The Italian celebrated twice as his rivals for the title, Aleix Espargaró and Fabio Quartararo, finished on the second row.
Winner of the last four races, Bagnaia posted a time of 1:46.069 to snatch pole by 0.090s from his factory Ducati teammate Jack Miller and Gresini Racing's Enea Bastianini, who completed the front row.
“I think this is my best lap. I had never done such a perfect lap," said Bagnaia, second in the championship standings 30 points behind Quartararo. “It is the best way to end this Saturday, watching the race. We are strong, but Fabio is strong too, so starting at the front is definitely an advantage."
Aprilia's Espargaró, three points behind Bagnaia in the overall standings, finished fourth ahead of Pramac Ducati rider Johann Zarco as Quartararo put his Yamaha into sixth on his final lap.
Honda rider Marc Marquez, a six-time MotoGP champion, finished 13th on his return to racing after recovering from surgery and missing the last six races of the championship.
Suzuki rider Joan Mir withdrew from the Aragon GP weekend after the third practice session due to an ankle injury sustained in his accident at the Austrian GP last month. The 2020 world champion will also sit out next weekend's Japanese GP at Motegi
