Max Verstappen completed a practice double for Sunday’s Mexican Grand Prix by edging out Lando Norris.
After leading the way in the first running at the Autodromo Hermanos Rodriguez in Mexico City, Verstappen – who has won 15 of the 18 rounds so far – set the fastest time in the day’s concluding running.
The Red Bull driver finished 0.119 seconds clear of McLaren’s Norris, with Charles Leclerc a quarter of a second back in his Ferrari.
Home favourite Sergio Perez finished fifth, three tenths behind Red Bull team-mate Verstappen, while Lewis Hamilton took seventh for Mercedes, a third of a second down.
Verstappen has dominated this year, and wrapped up his third successive world championship in Qatar earlier this month.
And the Dutchman will head into the remainder of the weekend in the breathless Mexico City air as the man to beat.
The high-altitude venue, which sits 2,200 metres above sea level, can often throw up anomalies, and Valtteri Bottas was a surprised fourth for Alfa Romeo, with Daniel Ricciardo sixth in his AlphaTauri, just three tenths off the top.
Hamilton finished a close second to Verstappen in the United States a week ago before he was disqualified for running an illegal floor on his Mercedes.
But despite his post-race exclusion, Hamilton hoped his speed in Austin would enable him to challenge Verstappen here.
However, the seven-time world champion failed to challenge the top of the leaderboard on Friday, finishing 11th and seventh respectively in the two sessions.
George Russell, who sat out the opening running as Mercedes blooded academy driver Frederik Vesti, finished 10th, half-a-second behind Verstappen.
Earlier on Friday, Ollie Bearman made history by becoming the youngest British driver to take part in a Formula One weekend.
Bearman, 18, competing for American outfit Haas, ended his F1 debut in 15th, only 1.6 sec slower than Verstappen and three tenths adrift of Nico Hulkenberg – a veteran of 200 grands prix – in the other Haas.
Bearman also finished one place ahead of double world champion Fernando Alonso.
F1 teams must run a rookie driver at least twice during the season and Chelmsford-born Bearman was handed his chance to impress, breaking the British record previously held by Norris.
Norris was three months shy of his 19th birthday when he took part in practice for McLaren in Belgium in 2018 before he was promoted to a race seat the following season. Bearman turned 18 in May.
The teenager, a member of the Ferrari academy, has taken four victories in F1’s feeder series Formula Two and is sixth in the standings ahead of next month’s season finale in Abu Dhabi.
