MIAMI GRAND PRIX FREE PRACTICE TWO - AS IT HAPPENED

With 1:29.938

Leclerc is third, Perez third, Hamilton in fourth.

Verstappen set no time after his struggles, and Sainz is down in 11th.

We'll have practice and qualifying coverage tomorrow and the full race on Sunday. Thanks for reading today.

Yet again a problem for Red Bull. If Ferrari put in a solid performance this weekend it could give them a huge advantage if the Austrian-sponsored side can't get their act together soon.

Russell first, Leclerc second, and Perez third. For now.

Hamilton, Alonso and Norris are the next three. This could be the most competitive race of the season.

Latifi for Williams is out on the side on the right, but it should be easy to get it off the track at the moment. It should be straightforward to roll it behind the barriers, but we're stopped for now.

Hamilton is third fastest on his out lap, too. Have they fixed their big problem?

Verstappen and Stroll in the clear for now.

There are more problems for Red bull. There seem to be flames on the right rear, and there are potential problems - there's an investigation over and incident between the Dutchman and Lance Stroll.

If he really cannot steer it's hard to imagine he will be found at fault, but let's find out.

Sainz is fastest so far, on 1:30.964.

Almost all of the rest of the pack are out on an out lap. Just Bottas and Sainz not running for now.

Here's the Spaniard just spinning out.

He's out on a corner again. This is getting painful to watch as the Spaniard fails at one session after another to keep his car on the track. At some point this will cost him his position in the team.

The drivers are all pushing hard today as they look to discover the best places to take advantage of the new and unknown track.

Some trouble for the German, and he is back into the pits. It appears very unlikely he'll be back out today.

Is this... Is this banter?

We're a few minutes away until the day's second and final practice session gets underway.

Here is the AlphaTauri getting into a hot, on-the-beat funk about his team bothering him during the first session.

Here's the moment that Sainz slipped up and almost damaged his car - he was fortunate to escape with a puncture only, and will presumably be fine for the second session, which begins in around an hour.

Here is our report from the first session, with Max Verstappen lurking in third.

Mercedes' Andrew Shovlin is content with the start from George Russell (second) and Lewis Hamilton (eighth) after the first practice session.

In a little over an hour we'll be back out for the second session.

That's it for FP1, with a time of 1:31.098 giving Leclerc the best time of the session.

Russell in second, Verstappen third.

The Ferrari man has the eighth fastest time of the day so far, but there is a little problem as he suffers a puncture and has to come back in.
