F1 Brazil GP: Lando Norris wins sprint as Oscar Piastri cras...

Lando Norris reinforced his Formula 1 championship lead after winning a red-flagged sprint race at Interlagos, while title rival Oscar Piastri crashed out of third.

Norris started Saturday morning's 24-lap race from pole, with the Sao Paulo circuit still damp in places following overnight showers. The medium-shod Briton held the lead from soft tyre starter Mercedes' Andrea Kimi Antonelli and Piastri, who had also opted for mediums.

But Piastri crashed out of third on lap 6 after slipping on Turn 3's wet inside kerbs, veering into the outside wall. Behind the Australian, Nico Hulkenberg and Franco Colapinto followed his example with nearly identical spins, with Hulkenberg escaping with minor repairs to his Sauber while Colapinto's heavy smash in the Alpine brought out the red flag for barrier repairs.

Norris controlled his lead on a rolling lap 9 restart, while behind him George Russell briefly snatched second away from Mercedes team-mate Antonelli, before the Italian rookie retaliated into Turn 4.

Reigning world champion Max Verstappen managed to fend off Fernando Alonso for fourth, after having passed the Aston Martin driver at the start of the sprint – Alonso unable to make his restart choice for the soft tyres pay off against the Red Bull on mediums.

But Verstappen, who had complained of his car's lack of grip throughout Friday, found similar struggles to get his RB21 to turn in, leading to a barbed exchange between the Dutchman and his race engineer.

Ferrari's Charles Leclerc and Lewis Hamilton followed in sixth and seventh, with Hamilton having won several spots off the start after only qualifying in 11th on Friday.

At the front, Norris initially maintained easy control until he started losing the benefit of his fading soft tyres, with Antonelli's longer-lasting mediums allowing him to get within DRS range.

Following a poor lap from the leader, lap 21 of 24 was the first opportunity for Antonelli to start sniffing around Norris' gearbox. But that was about as close as the teenager would get, with Norris hanging on to his first sprint win of the season.

Russell was third behind Antonelli, followed by a frustrated Verstappen. On lap 22, Leclerc capitalised on a slide from Alonso to breeze past the Spaniard for fifth, 10 seconds behind Verstappen, with Hamilton seventh.

Alpine's Pierre Gasly grabbed the final points place from Lance Stroll late on.
