F1 Miami GP live commentary and updates - sprint race

And...breathe. That was a pretty wild sprint, wasn't it? Thanks for joining us, and stay across Autosport and Motorsport.com for all the reaction from the sprint race and qualifying.

Oh, and don't forget to join us for qualifying later and for the race on Sunday at our Race Center Live! We'll have some special guests for a watchalong throughout the Miami Grand Prix.

We might have a few more penalties too - Albon's under investigation for a safety car infringement, while Bearman and Hulkenberg will have to see the stewards for an unsafe release. 

Spare a thought for Antonelli - the first corner was tough, but fair from Piastri, but the clout with Verstappen's Red Bull in the pitlane rather put a damper on his day.

Russell takes fifth over Stroll, as Lawson and Bearman complete the points-scorers - but surely, a penalty is coming Lawson's way, which might promote Tsunoda up to eighth.

Lap 18

We're going to finish under the safety car. Norris looked like he was in a tricky position with an extra lap on inters, as McLaren chose not to double-stack - but it's worked out nicely for the Briton here. 

Lap 17

With Verstappen handed a penalty and Lawson now under investigation, Bearman and Tsunoda might find their way into the top eight here.

"Really good stop guys, great job," Hamilton says; he was treading water in sixth before his stop, but the early Ferrari pit call pulled him up to third.

Lap 14

"There's a lot of debris, Turn 13/14", says Norris. He's after a safety car, as he's surely going to lose time to Piastri when he pits. Hamilton passes Verstappen for third - the Ferrari driver seemed to time his stop perfectly. 

Lap 13

Norris is forced to continue on the intermediates for another lap - Piastri pits from the lead. Russell and Alonso both stop, as Antonelli has to come in again.

Lap 12

Norris is right on Piastri's tail now, and will have DRS on his team-mate. Verstappen pits - but Red Bull release their driver into the path of Antonelli! This has broken Verstappen's front wing, while Sainz now has a punctured tyre following another incident! It's drama here!

Lap 11

Hamilton pits, and both Stroll and Sainz follow suit. Softs for Hamilton, while the others join Tsunoda on mediums.

Lap 11

DRS is now enabled. "It's dry enough for slicks," Antonelli says; and Tsunoda duly obliges with a set of medium tyres. Can the Red Bull driver make up the time?

Norris is now just 1.7s off Piastri now, so it looks like he'd spent the early laps saving a little bit. The McLarens have dropped Verstappen.

Lap 10

Russell has a little wide at Turn 7 and loses a bit of time to Antonelli - but he's angling for a switch between the two cars. Norris is closing on Piastri, while Albon is hustling Hamilton as the Ferrari driver is struggling slightly.

Lap 9

Piastri says the track is drying, but less quickly than anticipated. Meanwhile, Antonelli's continuing to come under fire.

"Inter is a bit faster than slick, but only by a little bit," Sainz says. Will we get any gambles?

Lap 8

Piastri is now three seconds up on Norris, with Verstappen a further 2.5s back. Russell's right on Antonelli's tail, as Hamilton's now under attack from Albon.

"I have no visibility, I don't know if it's the coating but it's terrible," Verstappen says. 

Lap 7

Antonelli went a touch wide at Turn 11, but preserves fourth. The cars look very tentative out there, as they're trying to find wet track off-line to keep the tyres cool.

Sainz tries to pass Ocon at Turn 17, but goes wide on the exit and narrowly evades the wall. Ocon retains 12th. 

Lap 6

No further investigation on the Antonelli/Piastri scuffle at Turn 1. Verstappen, meanwhile, has been noted for starting out of position on the grid. That's usually a slam-dunk, as it's sensor-based, but the stewards say no further action.

Lawson, meanwhile, is struggling to see with a crack in his visor causing it to mist up. 

Lap 5

Norris has broken away from Verstappen by over a second, as the top 10 appears to have spaced out slightly.

We got a replay of Bearman threading his car down the inside of Bortoleto and Doohan into Turn 1 - a nice little move there.

Lap 4

Piastri's already 1.7s up on Norris, who's trying to clear off ahead Verstappen. Antonelli's managed to stabilise to keep Russell behind, but a bit of youthful over-exuberance there into the first corner as he didn't fancy ceding the corner.

"It's drying very quickly," Piastri says. Anyone for slicks in a couple of laps?

Lap 3

Alonso's up to eighth, as Lawson makes up five spots to shuffle up to ninth - ahead of team-mate Hadjar, who's come under attack from Stroll.

Antonelli's about to park up in the pole slot, followed by the two McLarens. They're trying to hoover up that final bit of tyre temperature to get a good start.

The medical car is turning some laps, and the spray is nowhere near as bad as it was a few moments ago. It's still got the back end out, mind - so I don't think it's slick weather just yet. 

"No more rain expected currently," Ocon is told by engineer Laura Mueller. "We might finish on slicks," the Haas driver has suggested. 

Okay, make that 12:28. Maybe Brushy McGee was slacking, who knows? 

Sprint restart time

Our Saturday race should begin at 12:25pm local time - so, that's in just over five minutes' time. 

We KNEW the little spinny sweeper truck brush could do it. Good work, Brushy McGee - we'll make sure you're properly compensated for your work.

We've got a sweeper truck attempting to disperse some of the water on-track to ensure we get up and running reasonably soon. It still looks damp and overcast, but hopefully a small spinny brush can work its magic to de-wettify the circuit.

The drivers will park up in the pitlane, and we'll wait for the track to dry a bit before we get rolling again.

Lance Stroll reports that water was getting between his visor and his tear-offs, making visibility even more difficult. And it seems pretty unanimous around the field - "the worst visibility I've ever had in a racing car," was Piastri's view of the situation.
