Following a disrupted first day of running on Thursday night and Friday morning, most of which was held behind closed doors, fans were welcomed back into the grandstands to witness final practice on the streets of Las Vegas.
With the track re-opened for road traffic during the day, action got underway at 8:30pm local time on a circuit with different grip levels compared to how the drivers left it at 4am earlier in FP2 on the same the day.
Ferrari drivers Charles Leclerc and Carlos Sainz continued where they left off after taking a 1-2 in FP2, leading early doors in the same positions.
The first 20 minutes were marked by an odd duel between Leclerc and Kevin Magnussen, the Monegasque driver holding up the Haas driver before the latter seemed to return the favour.
At the halfway mark Red Bull got involved at the front, with Sergio Perez leading the way on softs by virtue of a 1m35.146s lap, before world champion Max Verstappen went half a second quicker with a 1m34.653s effort.
On softs Williams' Albon then split the Red Bulls and the Ferraris with third, on a circuit that his team is tipped to perform well at.
It took until the final quarter for the top times to tumble again, Russell beating Verstappen's benchmark by 0.068s as the track continued to grip up and more drivers shifted to qualifying simulations.
