Australian MotoGP rider Jack Miller has qualified fourth on the grid for the Aragon Grand Prix with championship leader Marc Marquez chalking up his ninth pole of the season.
Honda rider Marquez, 93 points clear of Italian Andrea Dovizioso with six races remaining, lapped the anti-clockwise MotorLand circuit near Alcaniz, with a best of one minute 47.009 seconds in what is his home event.
Quartararo, runner-up to Marquez at the previous San Marino GP and the only non-Spanish rider to start on pole so far this season, was 0.327 slower for the non-works Petronas Yamaha team.
Yamaha’s Spaniard Maverick Vinales completed the front row with Queenslander Miller one back having provisionally held a front row spot before Quartararo’s last lap.
“It would have been nice to get onto that front row but fourth, we’ll take it,” Miller told Motogp.com.
“We put in some really hard work in FP4 and even yesterday in FP2, trying to work out what the tyre is going to do.
“We got some work to do tonight to dial the bike in just a little bit more but very happy, we’ve done a great job so far this weekend and I’m looking forward to hopefully a strong race.”
Dovizioso was a distant 10th for the works Ducati team with Italian great Valentino Rossi sixth for Yamaha.
Sunday will be five-times MotoGP champion Marquez’s 200th grand prix start in all categories.
Spaniard Pol Espargaro, who rides for KTM, will miss the race after fracturing his left wrist when he crashed in practice.
