As it happened: Bagnaia wins first MotoGP Sprint of the year in Portimao

And we're underway with MotoGP P2 at Portimao!

Practice 2 is coming up in ten minutes time. The top ten at the end of P2 will gain direct access into Q2.

Good afternoon and welcome back to action from day-one of the Portuguese MotoGP.

It looks as though A. Marquez is going to end his first official session as a Ducati rider fastest...

Mir finds even more time as he goes second behind Marquez.

Big improvements from Mir as the Repsol Honda rider goes P3. Great opening practice for the former Suzuki rider.

A. Marquez goes fastest with a time of 1:338.782s.

Alex Marquez goes second - great lap from the Gresini rider. 

Some riders have chosen to fit new tyres and get a banker lap in during the closing stages of P1. 

Bagnaia goes second after finding pace on used tyres, although Martin still leads by two tenths. 

Under 15 minutes to go as Martin continues to lead the way from both Marquez brothers.

Joan Mir goes seventh as early signs from Honda are that they could be fighting for better results than initially thought. 

Martin's early pace is certainly laying down a marker. The Spaniard is nearly four tenths clear of M. Marquez. 

Make it Martin who jumps back to the top of the leaderboard with a sub 1m 40s lap. 

Marc Marquez has gone quickest after following his brother Alex, closely. 

Di Giannantonio has suffered a highside at turn five. Rider appears to be okay. 

Miller leads the way from Marini, as Bagnaia and Quartararo are both back out on track. 

The rain has stopped and lap times are beginning to come in.

Only Zarco and Jack Miller are currently out on circuit. 

Conditions are improving as Marini and Bezzecchi remain on-track with dry tyres. 

Luca Marini, Johann Zarco and Marco Bezzecchi are the only riders to set a flying lap thus far.

Big highside for Franco Morbidelli at turn eight as wet conditions have caught out the Italian. 

The track is soaking wet in sector one but appears to be in better condition in other parts.
