Carlos Sainz was third with Sergio Perez 0.598 seconds behind his teammate and also set his best time relatively early on.

Valtteri Bottas was seventh ahead of Nico Hulkenberg, was is racing at the Miami GP for the first time.
Mercedes suffering big issues in Miami
It’s been downhill for Mercedes since George Russell led Lewis Hamilton in FP1, with both drivers complaining about different issues in final practice.
The seven-time world champion was 13th, with Russell in 10th behind Alex Albon of Williams.
Hamilton thought he was losing a lot more time on the straights compared to normal, whilst Russell was struggling at Turn 2 over the bump, complaining of hopping.
Should the track not come towards them for qualifying, Mercedes may struggle to reach Q3.
Fernando Alonso and Lance Stroll were 12th and 14th for Aston Martin as they also appear to be lacking performance compared to earlier in the season.
