Qualifying at the Circuit of the Americas is now underway.
That's according to Ted Kravitz: "Not the case with Lewis Hamilton's car. The Sprint showed their tyre wear is off the scale. They have made changes, not as many with George Russell though.
It's a late one here in the UK with qualifying at COTA kicking off at 11pm BST.
It should be worth the late night though with four teams likely in the hunt for pole.
- Red Bull seem to be back to their best with Verstappen controlling the sprint race from pole position
- Ferrari's race pace and tyre wear was impressive. However, Leclerc expects qualifying today to be more difficult
- Norris happy with third in the sprint as he feels Verstappen and Ferrari have the edge
- Big changes needed for Mercedes after tyre troubles in the sprint
- Haas head of the midfield with both cars in the points
