Lando Norris stretched his Formula 1 championship lead to nine points after winning Saturday’s São Paulo sprint, while McLaren teammate Oscar Piastri suffered a major setback with a crash that dealt a heavy blow to his title hopes.

The McLaren duo began the day at Interlagos separated by just one point, with Norris starting from pole and Piastri lining up third on the grid.

But the Australian’s race came to a sudden end on lap six of 24, when he lost control on the wet kerb at Turn 3 and spun into the barriers — a costly error in a season defined by fine margins.

The sprint was red-flagged two laps later for barrier repairs, resuming under a rolling start with Norris leading from Mercedes pair Kimi Antonelli and George Russell.

Antonelli briefly looked poised to challenge for victory, closing to within a second of Norris on medium tyres compared to the Briton’s softs. However, the charge was halted when Sauber’s home favourite Gabriel Bortoleto suffered a frightening crash on the final lap, bringing out double yellow flags.

Bortoleto’s car went airborne and slammed into both sides of the wall, but the Brazilian quickly reassured his team over the radio that he was unhurt. After being checked at the medical centre and released, he jogged back down the pit lane to rejoin his crew.

Norris ultimately crossed the line 0.845 seconds ahead of Antonelli, with Russell completing the podium as Mercedes reclaimed second place in the constructors’ standings from Ferrari.

Red Bull’s reigning world champion Max Verstappen finished fourth, leaving him 39 points behind Norris in the overall standings. Ferrari’s Charles Leclerc took fifth ahead of Aston Martin’s Fernando Alonso, with Lewis Hamilton seventh and Alpine’s Pierre Gasly collecting the final point.

“It was tough — that makes the win even more rewarding,” said Norris. “It’s never easy here in Brazil. Mercedes were quick; I expected us to be a bit better, but they did a good job. I’m not sure how much of that was down to tyres, but I’m happy with the result.”

For Piastri, it marked another disappointing chapter in recent races, though he remained optimistic ahead of Sunday’s main event.

“I’ll try to put this behind me,” said the Australian, who lost the championship lead to Norris in Mexico last month. “There are plenty more points on offer tomorrow, so the better I do in qualifying, the stronger our position will be.”

McLaren team principal Andrea Stella struck a balanced tone after the session. “It’s just an episode,” he said. “Oscar has shown great pace this weekend. We’ll regroup, repair the car, and focus on the big points tomorrow.”
