Acosta down to a 1m28.381s now, he's over 0.6s clear of Marini now.
Marini the latest rider to go into the top-three with a soft rear.
Acosta also on the soft rear now and he improves his benchmark to a 1m28.507s. He's now 0.485s ahead of Marini in second.
Few run-ons in the last few minutes for Marc Marquez, first at turn one, then turn four. Not looking perfectly comfortable out there. Currently P6 in the session.
Martin out on the soft rear and jumps up to second, 0.162s ahead of Bezzecchi but still over 0.2s behind Acosta.
Moreira off again at turn four. He's gone straight on three times there in the first 25 minutes of this session.
Morbidelli has also run on at turn four. No crash for the Italian.
Crash for Zarco at turn four. As he was walking away, Moreira just narrowly avoided him as he ran on through the gravel.
So we mentioned Bezzecchi's decent start to the session earlier. He used the soft rear to do that. Quartararo also on the soft in third. Everyone else in the top-10 on the medium rear.
Decent start from Bezzecchi up in second place, better than this morning when he was sixth.
Still almost 0.4s behind Acosta, though - the Murcian still the only rider in the 1m28s.
Pace immediately a step up on FP1, or two or three steps.
Acosta straight down into the 1m28s and he leads by 0.4s ahead of Quartararo.
Moreira in the tow of Marc Marquez on his first flying lap. Almost cleaned the pair of them out as he lost control under braking. Well gathered in the end by Moreira.
Practice is underway in Austria as the Red Bull Ring pit lane opens.
Dry conditions as this morning for Practice, but much clearer skies.
Still not the warmest, though, with 20C air temperature and 19C track temperature.
Moto2 Practice is over at the Red Bull Ring. Salac ends fastest from Ortola and Holgado.
MotoGP coming up in just over 10 minutes.
Unreal save here from Eddie O'Shea in the Moto3 Practice!
Unfortunately for O'Shea it didn't do much for his position - P23 at the end of the session.
Into the final 15 minutes of Moto2 Practice now, meaning just half-an-hour before MotoGP starts.
Guevara still fastest from Alonso and Ortola in the Moto2 session, and looks like Sergio Garcia's bike has expired between turns five and six.
Moto2 currently on track for its Practice session. Izan Guevara was strong this morning, inside the top-three, and is currently fastest by almost 0.3 seconds ahead of David Alonso in Practice.

Austrian MotoGP, Red Bull Ring - Friday Practice Results

It's a perfect start to their home weekend for KTM - it's a 1-2 for them in FP1, Acosta ahead of Espargaro.
Martin takes third ahead of Marc Marquez, Zarco, Bezzecchi, Fernandez, Alex Marquez, Moreira, and Luca Marini who rounds out the top-10.
Pol Espargaro in the tow of Acosta goes up to seconds. New tyres front and rear for the Vinales replacement at Tech3. Still only Acosta in the 1m29s.
Alex Marquez, currently P6, has run off at turn four. Unsure what's happened, but his left downwash duct has become dislodged exiting turn three. Quite bizarre, never seen that before. He's made it back to the pits.
