Petronas Yamaha's Fabio Quartararo became the youngest ever MotoGP pol sitter at 20 years, 14 days after setting a new Circuito de Jerez – Angel Nieto lap record in qualifying, a 1:36.880 seeing the Frenchman beat teammate Franco Morbidelli by 0.082 as the new Petronas Yamaha SRT outfit lockout the front of the grid, with Repsol Honda's Marc Marquez in third, 0.090 behind Quartararo. At the start of the session it was Repsol Honda's Jorge Lorenzo who led the field onto their first flying laps and stalking the number 99 was teammate Marquez, and the reigning champion was able to take full advantage of Lorenzo’s draft to set a 1:36.970. Marquez emerged on his second set of Michelin slicks before the rest and it was looking good for the Honda rider to move the goal posts further from his rivals, but he lost time in the last sector and it was as you were when the rest of the field ventured back out on fresh rubber. Lorenzo wasn't faring so well however, and a crash at Turn 2 ruined his qualifying. Quartararo then put in a sensational lap to go into P1 with a blistering 1:36.880 - the best lap of the weekend and a new lap record, just ahead of Morbidelli, who propelled himself into P2, 0.082 off his teammate and 0.008 ahead of Marquez. At this point, Marquez was gearing up for his third run. A tenth down in the first sector wasn’t what he was looking for and, in true 93 fashion, he was on ragged edge – but this proved costly. Horribly out of shape at Pedrosa Corner, he then compromised his hot lap even further with a huge front end slide at Turn 7 to end his pole position hopes, handing Quartararo his maiden MotoGP P1 grid slot start. It means Petronas Yamaha took a sensational Spanish GP qualifying 1-2. Marquez completes the front row, just ahead of Ducati's Andrre Dovizioso in fourth, with Q1 graduate Maverick Viñales piloting his factory Yamaha to P5 after a good second run in Q2 to finish 0.234 from pole. Last year’s pole man Crutchlow completes the second row in sixth. Danilo Petrucci, a late crasher at Turn 1, will start seventh after looking strong all weekend. The Italian only 0.3 from P1 as he’s joined by Takaaki Nakagami (LCR Honda Idemitsu) - his best qualifying in the premier class - and Alex Rins (Suzuki) on the third row.
