Sergio Perez has ended the final practice session from Miami as the fastest driver, setting a 1:30.304 for Red Bull.

Just under two-tenths of a second behind the Mexican was Charles Leclerc for Ferrari, whose final effort before the chequered flag elevated him into second place.

The Dutchman was forced to brake heavily as he started to spin, before coming to a stop just short of the barrier.

Fernando Alonso was fourth for Alpine, while Sebastian Vettel was an encouraging fifth for Aston Martin, ahead of compatriot Mick Schumacher in sixth.
Carlos Sainz, who ended Friday with a crash, was seventh, leading the second Haas car of Kevin Magnussen.
Alexander Albon was ninth, while Lando Norris rounded out the top 10 for McLaren.
Mercedes’ strong pace from FP2 didn’t come to fruition in the final practice session, with Lewis Hamilton and George Russell ending the session in 15th and 17th respectively.
While Alonso produced a strong time for Alpine in fourth, team-mate Esteban Ocon had limited running after he crashed his car.
The Frenchman lost the rear of the A522 as he rounded Turn 13 and suffered hefty damage after hitting the concrete wall.
