Lando Norris unexpectedly gave up the win in Saturday's Qatar Grand Prix sprint race, having led from lights out.
The Brit, no longer fighting for the drivers' championship after Max Verstappen wrapped up the title in Las Vegas, allowed team-mate Oscar Piastri past him on the final straight to pay back the latter's sacrifice in Brazil.
Meanwhile, Max Verstappen struggled mightily with his Red Bull in the early stages, losing places and dropping all the way out of the points on the opening lap as he dealt with snaps of oversteer, although he worked his way back up into eighth place.
The result all but knocks Red Bull out of constructors' championship contention, with McLaren adding a further 14 points to the gap between the teams. Sergio Perez, who finished 20th out of 20 runners, did not help his team's cause.
