McLaren made a statement in their constructors' championship fight against Ferrari and Red Bull on Saturday in Qatar, extending their narrow lead in the last sprint race of the year.
Lando Norris led from lights to the final corner, before handing the victory to team-mate Oscar Piastri over the finish line to pay the Australian back for his own sacrifice in the sprint race in Brazil.
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.
