Norris has been warned about lockups into Turn 1. "They'll end this stint," he is told. We've seen some big smoke signals down there this weekend, and more would spell disaster today.
Perez is going very slow, and it looks like we will get both Cadillacs failing to finish. He makes it to the pits, but questions will be asked as to whether completing the lap with a damaged car was within the rules.
No further action for Leclerc on a yellow flag infringement.
Williams, and particularly Sainz, fill the villain role this weekend. Erratic driving repeatedly in FP sessions, and then colliding with the leader while lapping at the rear of the field. Has Sainz ever had a worse weekend?
Antonelli is defending from Norris, but this will be a simple move with boost on the straight.
Out of the final corner, Norris pins it and throws it to the inside of Turn 1, he holds the lead with the switchback into Turn 2. Cool and collected from Norris.
A five-second penalty for Sainz. That is incredibly lenient, especially given the magnitude of the effect it has had on the race.
Somebody get Sainz an appointment at Specsavers, please. This is not the first time he's been in the thick of it this weekend.
"Don't talk to me," is the clear message from Piastri. He is less than pleased that McLaren put him out in traffic, and has cost him the victory.
Norris is now pulling clear of Piastri. Verstappen leads from Antonelli.
Norris comes out of the pits in the lead, and this will sting for Piastri, who has done nothing wrong.
The incident is under investigation, but that will be no consolation for Piastri.
Piastri reports contact with Sainz. The Williams driver was busy battling with Alonso, and Sainz pulled across on Piastri, making contact and putting the Australian onto the grass. There will be a hefty penalty, but it could already have killed Piastri's race.
Piastri is having an adventure out there, getting sideways when trying to pass the traffic. That was very rude from the backmarkers.
In comes Leclerc from fourth. It sounds like Antonelli may not be able to make the one-stop work, as he complains about the tyres.
Antonelli is with Leclerc now and is searching for any opportunity to make a pass. Leclerc, like Norris, is going long on this stint.
There is a chance that McLaren has blinked early here, with Ferrari forcing their hand.
Piastri comes out ahead of Hamilton by three seconds. Norris needs to pit now to have any chance of staying ahead of Hamilton. He may elect to stay out and go long, taking the tyre offset to the end, which may help him against Piastri later on.
Norris complains that McLaren "won't let me" pit. He's the second driver on the track though, so it's Piastri's decision.
But Hamilton is flying on his new hards, so McLaren has to pit one of the cars.
In comes Piastri.
Hamilton finds a way through, and Norris demands to 'box this lap'. The mechanics come out, but both drivers continue. "Lando, we can't, I'm afraid."
In comes Hamilton for a second stop on lap 31. Fresh hard tyres. This looks almost like a three-stopper now, with more than half the distance remaining.
The wing adjust wasn't completed, and Hadjar is now ahead of the Ferrari.
A third wide moment of the race for Norris. This time, it's up at Turn 4. He goes across the aggressive kerbing, but is now 1.5s back on his team-mate.
Hamilton and Leclerc are about to get some bad news, as Antonelli comes charging up to the pair of Ferraris. Verstappen has now managed to pull 2.6s clear of Hamilton.
McLaren is still targeting 'plan A', but Piastri reports that his tyres "aren't great". Norris will take some extra momentum from that.
A thing of beauty. Verstappen's lunge on Hamilton.
Turning to Aston Martin briefly, we've given the team a lot of stick, but for the first time this year, Alonso is lapping in the top 10. Or at least, he was. Lawson pushes him back down to 11th.
In comes Antonelli on lap 22. Possibly calling time on a one-stop plan. A 2.1s stop, and he returns to the track in sixth place.
