Kimi Antonelli pits for fresh mediums, so this appears to be the start of the window for a second stop for some teams.

Those who have come in have done around 18 laps on the mediums, but Oscar Piastri appears to be aiming to go the distance on them.

Fernando Alonso is into the pits for a second time and puts on fresh mediums. He did 18 laps on his first set.

Well, we had some excitement with Lewis Hamilton pulling off several impressive overtakes but things have become a bit of a procession now as most drivers appear to be in tyre-saving mode.

Lewis Hamilton does his quickest lap of the race so far and could be in with the chance of an overtake move on Alex Albon in the next couple of laps. There's 1.2 seconds between the two.

We know the McLarens have been good with their tyres this year and keeping them in check for longer than their rivals.

Now we've got two drivers from the same team battling it out for the championship on different compounds of tyre.

Lando Norris runs wide at Turn 10 and that's a bit costly as he loses more than a second to Oscar Piastri. The gap is now 9.2 seconds.

Not too many close battles in the top 10 at the moment.

Yuki Tsunoda is perhaps the closest to an overtake as he closes in on Pierre Gasly in 11th.

Lando Norris is looking strong where is he but he's unable to make any inroads into Oscar Piastri.

We will find out sooner or later because Piastri will start putting in some quick laps because he will want to use up that tyre if he's made a decision to go to a hard tyre.

Then he will come out ten seconds behind Norris and then he's got a bit of a race on his hands.

Now Lando Norris does the fastest lap to keep the pressure on Oscar Piastri should he pit again, which looks likely.

This is what you expect when you've got a downpour. You get a lot of rubbish dragged onto the track and so when you go to the slick tyre, the slick tyre picks up all the grit on the tyre and then starts to cut the tyre.

Now Oscar Piastri is the fastest man on the track and increases his lead slightly over Lando Norris to 8.3 seconds.

"The medium tyre is degrading fast."

Carlos Sainz is over the radio to say the medium tyres are degrading fast.

Franco Colapinto certainly seems to be struggling with them as he sees three cars pass him as he drops to 17th.

"I think it will be tough [on the medium tyre] to get to the end."

Oscar Piastri does not sound convinced his mediums will last until the end of the race. He's on mediums whole Lando Norris is on hards.

Lando Norris has done another fastest lap which is a good four-tenths of a second faster than Oscar Piastri.

Norris seems to be very happy on these tyres and they should be durable, they should get him to the end of the race without too much loss of performance.

Oscar Piastri continues to look comfortable out in the lead and has an eight second advantage over Lando Norris.

Meanwhile, Isack Hadjar pits for the second time to move onto hard tyres.

And Gabriel Bortoleto gets his wish as he uses the tow before sweeping past Nico Hulkenberg down the straight and into ninth.

Gabriel Bortoleto is behind his team-mate Nico Hulkenberg in 10th and is getting a bit frustrated. He feels he is faster than Hulkenberg and says over the radio that he needs to let him go.
