McLaren's Lando Norris extended his championship lead to nine points as he won the Sao Paulo Grand Prix sprint race while team-mate and title rival Oscar Piastri crashed out.
Piastri lost control through Turn Three on lap six of the race and spun into the barriers, the latest in a series of blows to the Australian's title chances.
The race was stopped after both Sauber's Nico Hulkenberg and Alpine's Franco Colapinto crashed in the same place, fortunately neither hitting Piastri's car or each other.
When the race restarted, Norris held off a challenge from Mercedes' Kimi Antonelli to take the win, while the second Mercedes of George Russell took third from Red Bull's Max Verstappen.
The race ended just after Gabriel Bortoleto had a high-speed crash in his Sauber at the end of the pit straight.
Bortoleto was trying to pass Williams' Alex Albon but appeared to hit a wet patch on the track as he braked. He smashed into the inside wall and then spun wildly across the track into the barriers on the outside.
