Looks like a ride height device failure that caused Raul Fernandez to retire. Unfortunate, he was running in the top-six.
It's a sixth straight Sprint win for Marc Marquez in Austria and a first MotoGP win of any kind at the Red Bull Ring.
Alex Marquez takes yet another second place and a first premier class podium in any MotoGP race in Austria.

Acosta losing some time to Bezzecchi but still has 0.8s for the final podium spot.
Binder fifth after passing Fernandez before the Spaniard dropped out.
Marc Marquez now to the lead at turn three on lap 10. Small mistake from Alex at the chicane.
0.2s now between the front two, Acosta now 2s off the lead and 1s clear of Bezzecchi.
Looks like a crash for Raul Fernandez, he's dropped from 6th to 19th.
Bagnaia has now dropped to the very back of the field after running on at turn one. And he's now pitting to retire.
A lot of track limit warnings out there: Acosta, Bastianini, Aldeguer, Quartararo, Mir.
Alex Marquez continuing to lead. Acosta now 1.4s off the lead, so it's between the front two for the win here. Half-a-second between them at half-distance.
Morbidelli's run on at the chicane and dropped back to 12th.
Bagnaia now back to 15th as Jorge Martin goes through. Mir next up for Bagnaia.
Acosta's overshot turn four and lost a lot of time with that, he's now almost a second off the lead.
Front three starting to get away from Bezzecchi in fourth now. Acosta still right with the front two, though.
Bagnaia, by the way, still 14th and can do nothing with Marini ahead.
Still Marquez leading Marquez, fastest lap for Alex that time. Acosta has a track limit warning.
Alex Marquez continues to lead at the end of lap two, but Marc is all over him. Acosta right there in third, too, Bezzecchi just falling off slightly. Then it's Fernandez in fifth from ninth on the grid.
Acosta up to third past Bezzecchi at turn 2a.
Strong start from the Spaniard from seventh on the grid.
Aldeguer also span off the line, he was directly behind Bagnaia in sixth but somehow came out of it all ahead of Bagnaia and inside the top-10 in ninth.
It's lights out in Austria for the MotoGP Sprint, and a holeshot for Alex Marquez, Marc Marquez second and Bezzecchi third.
Awful start for Bagnaia, he span off the line and is 14th.
Riders are off on their warm-up lap ahead of the Sprint. 14 laps of the Red Bull Ring coming up.
With Marc Marquez as far clear in the championship as he is, perhaps the main battle in terms of points now is between Francesco Bagnaia and Alex Marquez over second.
The position currently belongs to Marquez, 48 points ahead of Bagnaia, and the Gresini rider starts in front this afternoon after being only 0.016s behind Bezzecchi in Q2.
But Bagnaia has won two Sprints and five GPs at the Red Bull Ring and has looked good in terms of pace this weekend - coming from third, the Italian should be capable of a strong performance this afternoon.
There was some light rain around after qualifying earlier, but it's full dry now.
30C air temperature and 43C track temperature currently being recorded.
Still over 10 minutes before the start so time to change, but at the moment the tyre choice is almost uniform.
Everyone on soft-compound rear tyre and medium-compound front. Only Pedro Acosta is on something different, as he has chosen the hard-compound front tyre - for now at least.
Home race for KTM this weekend and, despite a promising Friday, Saturday hasn't gone quite as hoped so far.
Maverick Vinales has withdrawn from the weekend after being declared unfit after qualifying as he continues to recover from the injuries he sustained in Germany before the summer break.
Brad Binder made it directly through to Q2 in Practice, but was only 11th this morning.
Pedro Acosta was second-fastest to Marquez yesterday afternoon, but could only manage seventh in Q2.
The best-placed KTM on the grid is Enea Bastianini in fifth, but even he has struggled at times this weekend, most notably in Practice yesterday when he ran on at turn four on multiple occasions.
Acosta is probably the rider most likely to make something for KTM, but coming from the third row will not be easy. Bastianini is in a better position on the grid but he has been less consistent than his Spanish colleague.
