Leclerc set the early pace in Free Practice 1, which was curtailed after only eight minutes due to a water valve cover working loose and smashing the bottom of team-mate Carlos Sainz’s car.
He also paced FP2 with a fastest time of 1m35.265s, after a lengthy delay while repairs were conducted to the track.
The hugely anticipated first running on the new 3.9-mile street track didn’t last long. The water valve cover issue that sidelined Sainz’s car brought the session to an early end after just eight minutes.
Sainz's Ferrari crawled to a halt between the Bellagio and Paris hotels on the Strip, his onboard camera showing that his car had been rendered immobile by an impact from something on the track.
