A late red flag for an Alex Albon crash meant a very unusual order in final practice for Formula 1's Las Vegas Grand Prix.

Key moments

• Russell fastest from Piastri
• Williams fast but Albon causes red flag
• Ferrari doesn't get a run on softs
• Verstappen can't show his hand either

George Russell led the session for Mercedes, ahead of Oscar Piastri's McLaren and an extremely surprising appearance in third place by Williams's American rookie Logan Sargeant in third.

But that picture is a skewed one.

Most drivers were finding that their best pace came on a second, third or even fourth flying lap on a set of softs, with cool-down laps in between.
