Marc Marquez weathered a late challenge from his fellow Ducati riders to claim pole for MotoGP's 2025 Aragon Grand Prix.
Marquez's pole looked virtually assured after the opening Q2 runs, in which he was alone in dipping into the 1m59s range and did so with just one flying lap - but he suddenly came under threat in the closing minutes of the shootout.
As Marquez backed out of his first push lap on the soft, his brother Alex and VR46 Ducati rider Franco Morbidelli both overhauled him on the timing screens, meaning the six-time champion now had to improve.
But he did just that, lowering the benchmark to a 1m45.704s with the aid of the best third and fourth sectors of the session.
Morbidelli was then just 0.026s off Marquez after three sectors of his final attempt, but couldn't keep it up in the final sector, leaving him third behind both Marc and Alex - the latter limited to one bike after crashing in Saturday morning practice.
Pecco Bagnaia made it a Ducati 1-2-3-4, having recovered from a poor opening run in Q2.
And the top eight ended up fully made up of Ducatis and KTMs, with Pedro Acosta (KTM), Brad Binder (KTM), Fermin Aldeguer (Gresini Ducati) and Maverick Vinales (Tech3 KTM) all slotting in close behind Bagnaia.
Fabio Quartararo (Yamaha) repaired the damage of his messy Friday by fighting through Q1 but could only muster ninth in Q2, his run of three successive MotoGP poles coming to an end.
Fabio Di Giannantonio (VR46 Ducati) also made it through Q1 - putting things together on his final lap - but was in the end the last of the Ducatis in 10th.
The Hondas of Joan Mir and Johann Zarco were last in Q2, both over a second off, with Mir having destroyed one of his bikes in a fast Turn 2 crash in pre-qualifying practice.

Raul Fernandez had looked on course for a Q2 spot before being thwarted by Di Giannantonio at the last moment - and will start on row five alongside the Yamahas of Jack Miller and Alex Rins.
There was just 0.154s in Q1 between fifth-placed Rins and the fastest time of the session, yet a chasm of over 0.6s between Rins and sixth-placed Miguel Oliveira, Miller's Pramac team-mate.
British Grand Prix winner Marco Bezzecchi's session fell apart spectacularly, with an instant crash at Turn 3 on his first Q1 flyer and then a technical issue on his second bike that convinced him to return to the pits.
Reportedly without any quick fix available, he was sent out again for one flying lap - which was only enough to snatch the penultimate spot on the grid from Somkiat Chantra.
