Hamilton could only qualify down in 11th during Friday's sprint qualifying, being beaten by British teenager Ollie Bearman in the Haas, and his weekend went from bad to worse as Sergio Perez, Franco Colapinto and Nico Hulkenberg all passed him.
Piastri had previously said that he may give up the victory in order to help Norris' drivers' championship battle, with all eyes on team orders as the race continues.
McLaren's Brazil championship challenge
While McLaren were desperate for a one-two in the sprint race in order to extend their gap over Ferrari and Red Bull in the constructors' championship standings, all eyes were on the drivers' championship battle.
