Lewis Hamilton made a good start to the weekend on which he can clinch a sixth world title with fastest time in Mexican Grand Prix first practice.
Hamilton needs to out-score team-mate Valtteri Bottas by 14 points to seal his sixth world title on Sunday.
The headline lap times are hard to read – not only was Leclerc running on harder tyres, which suggests his lap was the de facto fastest of the session, but Albon and Bottas, who were 0.6secs off the pace, set their best lap times before the red flag and the others after it, when the track would be in better condition.
