Full live text commentary for the F1 United States Grand Prix Sprint at Circuit of The Americas in Austin, Texas
Trouble in the Red Bull camp? Tsunoda accuses Lawson on the radio of intentionally being slow in the corners to disrupt him - the Japanese is down in 13th, ahead of the Alpines with both Gasly and Colapinto having a wild moment each on their initial runs
Work to do for Piastri though as he slots into seventh place behind Verstappen, Leclerc, Norris, Hamilton, Antonelli and Sainz
Norris rebounds back to the top of the timesheets but it's only briefly as Verstappen goes quicker still moments later
Antonelli sets the early standard in Q2, followed closely by Sainz and Bearman
Q2 is go - McLaren looked a bit vulnerable in a scruffy session but let's see what happens when the new tyres go on
16- Bortoleto
17- Ocon
18- Stroll (20th after penalty is applied)
19- Albon
20- Hadjar
Albon leaps to eighth... and then drops right back down again because his lap time has been cancelled.
It leaves him 19th, ahead of only Hadjar.
Stroll also had his lap time cancelled and he is 18th, being joined by Bortoleto (16th) and Ocon (17th) in the drop zone
Tsunoda and Colapinto live to fight another day after Albon and Stroll's cancellation come to their rescue
Colapinto pops into 15th, demoting Bortoleto - all eyes on Albon now, but he has just set the fastest S1 of all
Ocon, Stroll, Colapinto and Albon are now facing the Q1 drop zone as a flag drops
Verstappen on new boots displaces Russell to move to the top of the timesheets by 0.104s
Elsewhere, Hulkenberg is up in fifth
Russell and Antonelli punch in a 1-2 to give the others a benchmark to aim for - two minutes remaining
Lando Norris in a little bit of trouble here as he can only manage seventh fastest despite being quickest of all in Sector 2.
Less than 4 minutes in this session remaining
Charles Leclerc heads up the timesheets from Verstappen, Hamilton, Sainz and Alonso.
The drop zone is occupied by Stroll (who has a penalty), Colapinto, Albon (who abandoned his first lap), Bortoleto (who had a lap cancelled) and Hadjar (who won't head out again after his crash).
Final flyers about to get underway
Lando Norris doesn't exactly hit the ground running again as his first flying lap is nixed by a sliding rear out of Turn 8, which leads to him running right off track at the fast-following Turn 9.
Let's try that one again
Charles Leclerc moves to the top, 0.065s quicker than Verstappen with Hamilton third, Alonso fourth and Piastri fifth.
Worth noting that Verstappen, Piastri and Norris (who has just started his first flying lap) are on used tyres for now though
Fernando Alonso goes quickest, followed by George Russell and Kimi Antonelli in third.
Well, until Max Verstappen moves to the top
Nico Hulkenberg is first across the line with his team-mate Gabriel Bortoleto chasing him - advantage the German between the Sauber drivers.
Oliver Bearman splits the Saubers with his first flyer
Bit of a clamour a full 3 and a half minutes before the session restarts as every driver piles out of their pit box...
Don't know about you, but I'd be tutting loudly and waving my hands around if I was stuck at a traffic light for more than 30 seconds.
F1 drivers are clearly made of different stuff
The wind is up at COTA, which might help explain how Hadjar got so unsettled before crashing into a barrier emblazoned with a pasta brand
He was the first to go through the eases at full speed, so might be something to watch when the session resumes
Zak Brown concedes he may have been a touch hasty in his assessment of the Sprint Race T1 crash that eliminated his McLaren drivers, telling Sky Sports F1 that he can't really pin the blame of Nico Hulkenberg as he had done.
A heavy thump for Hadjar as he rounds the high-speed esses at the start of the lap.
The rear of the Racing Bulls getting away from him as he entered the final fast right-hander and with the barriers not terribly far from the track, it's a big wallop that leaves his car heavily damaged and Hadjar at the back of the grid tomorrow.
Bad news for everyone else, Hadjar was the first driver to attempt a lap, so that's some scrubbed tyres with no lap times for the rest of the field
Isack Hadjar is into the barriers with considerable damage to his Racing Bulls
Driver appears to be ok as he bashes the steering wheel in frustration but the session has been stopped to clear his second-hand car
The drivers have taken so long to crawl out of the pit-lane to ensure there is space between themselves and the car in front that both McLarens are now queued up and about to hit the track again
A queue in the pit-lane as the drivers wait for the green light...
They don't include McLaren though, still some busy bees working around the cars but the drivers are seated and settled
A day to forget for Lance Stroll.
The Aston Martin driver had already damaged his car at Turn 1 in the concertina melee during the Sprint Race but then went and finished the job later on in the race when he torpedoed Esteban Ocon at the same corner towards the end.
There was little doubting that Stroll - coming from a looooong way back and locking up as he tried to get it stopped - was at fault for the incident that eliminated both drivers, so it's little surprise stewards have acted accordingly and given him a five-place grid penalty on wherever he qualifies now
Right, that's enough talk about the Sprint Race, let's focus fully on qualifying for Sunday's full 56-lap Grand Prix...
McLaren has something to prove, Verstappen is the man in form and Russell is keeping its foot in.
Sprint Race qualifying threw up a few surprises - time to see if this more important grid-forming session will throw up a similar result
