Miami Grand Prix: Charles Leclerc on pole as Ferrari take front row lock-out

Charles Leclerc led Carlos Sainz in a Ferrari front-row lock-out at the inaugural Miami Grand Prix.

The Dutchman made an error at Turn Five, running wide, swearing on the radio as he realised he had messed up.

Red Bull's Sergio Perez was fourth ahead of the Alfa Romeo of Valtteri Bottas and Lewis Hamilton's Mercedes.

Qualifying was held in front of a phalanx of celebrities led by former First Lady Michelle Obama at a race that has quickly jumped to the top of the list of Formula 1's most glamorous and sought-after events.

A crowd said to be 82,500, after tickets sold out within a day of going on sale last year, cheered Leclerc as the championship leader crossed the line for his third pole in five races so far this year.

"It is incredible to be here and see how the sport has grown in the US in the last few years," Leclerc said. "It's amazing."

Leclerc referenced the error he made chasing Perez for second place at the last race at Imola, which dropped him from third to sixth and cost him seven points in the championship.

"The last weekend hasn't been great for me - I did a mistake in the race," he said. "But today went well.

"Red Bull are extremely quick in the straight lines. We are quick in the corners and it will be a tight challenge and hopefully we will come out on top."

Verstappen bounced back from a difficult Friday in which he lost plenty of running because of overheating problems in the first practice session, a gearbox change which delayed his start to the second, and then a hydraulic leak.

"Overall, I was pretty pleased with qualifying," he said. "I only did four or five laps yesterday. Today was about learning the track and the car.

"I was pleased to be so competitive. Overall we did a good job but we have to stop making the weekends so difficult. The car is handling quite well and I am looking forward to it."

Sainz, too, bounced back from a difficult Friday, when he crashed heavily early in second practice.

To be only 0.19 seconds behind his team-mate, a renowned expert qualifier, after that was a decent achievement. He pipped Verstappen by just 0.005secs.

Mercedes flatter to deceive

Mercedes failed to live up to the promise they had shown through Friday practice, when George Russell was consistently close to the top of the times and actually ended the day fastest after the team introduced upgrades to their car.

Before qualifying, team boss Toto Wolff had cautioned against expecting too much of the team, saying: "We need to be also honest with ourselves: it's not like that we have brought a ground-breaking solution."

And he was proved right, as both drivers struggled throughout the session.

Russell in fact failed even to make it into the final part of qualifying and ended up 12th, saying to the team: "I don't think that was good enough. I just didn't have the confidence in the car today."

Hamilton fared better. He had a tricky first session and was on the verge of being knocked out at the first hurdle until a strong lap right at the end of it, but he was Mercedes' strongest performer after that.

But even so, he was unable to get close to the dominant forces of Ferrari and Red Bull, and was even beaten by former team-mate Valtteri Bottas in the Alfa Romeo by 0.15secs.

Alpha Tauri's Pierre Gasly and Yuki Tsunoda were seventh and ninth, split by McLaren's Lando Norris, with Aston Martin's Lance Stroll impressing by making it into the top 10.
