Portuguese MotoGP at Portimao: Sprint race as it happened!

The shootout for pole is go in Portimao! 

It's Alex Marquez and Acosta who advance to Q2 as Espargaro is the first rider to miss out. 

Acosta goes nearly three tenths quicker than Alex Marquez. What a lap from the rookie.

Riders are now heading back out for the second and final runs. Acosta leads Marquez with Aleix Espargaro the first rider currently missing out on Q2.

Alex Marquez and Pedro Acosta are currently dominating the early running as Acosta leads Marquez by 0.012s.

MotoGP Q1 at Portimao is underway!

Up next is Q1 which will see Pedro Acosta look to make his way through to Q2.

After a relatively quiet session from the title hopeful Jorge Martin pushes his Pramac Ducati from 15th to eighth. The Spanish rider improves again to sixth as the chequered flag comes out.

This looks good for Vinales upcoming qualifying - he would have gone faster on his next time attack but hit traffic on track!

Acosta is really impressing here as he goes lower again. Maverick Vinales keeps the pressure on and takes over with a 1m 38.720s

As we head into the final five minutes Brad Binder has begun to move up the order, claiming seventh, while championship leader Francesco Bagnaia also improves to fourth from 15th for Ducati.

Rookie Acosta is back on track and back on top of the timesheets - his 1m 39.115 takes over as the best time in the session.

The pit boxes remain busier than the track  -  the current top five in the session are Marc Marquez, Maverick Vinales, Fabio Quartararo, Pedro Acosta and Marco Bezzecchi. Miguel Oliveira heads out on home soil to see if he can make his way into the top ten.

Jack Miller is having a mini repair job after something flew off of his Red Bull KTM at turn one - the Australian is currently 12th, but only half a second off the top time.

Marco Bezzecchi is next to find improvements, moving from eighth into the top five as most of the riders are now in the pits as we hit the half way mark in FP2.

It is a quick moving session, with Marc Marquez moving ahead just seconds later, with his lap taking him from seventh to first!

Another push from Vinales sees him move into p1 in the session - the Aprilia rider has been suffering with stomach issues this weekend.

It is Alex Rins who now sits in second behind his team mate, with Maverick Vinales third.

Acosta is dethroned by Fabio Quartararo! The Yamaha man is now top with just over twenty minutes remaining.

The Marquez brothers are among the first to set lap times with Marc fourth and Alex briefly top before Pedro Acosta moved to the top of the timesheets

FP2 is live! The bikes head out on track for the half an hour session before qualifying  in the Algarve.

The track conditions from Friday have all been cleared - the track is much cleaner and the weather air as we head into the first MotoGP session of the day.

Good morning and welcome to coverage of the second day of the Portimao MotoGP. FP2 is due to get underway at 10:10 am UK time.
