McLaren's Oscar Piastri won for the fourth time in six races this year as he beat team-mate Lando Norris in an action-packed Miami Grand Prix.
Both McLaren drivers fought intense battles with early leader Max Verstappen's Red Bull as they moved up to the front of the field.
Piastri, who started fourth, drove a race of clinical excellence to pass both Mercedes' Kimi Antonelli and then Verstappen to assume the lead, before managing his gap to his pursuers to the end.
Norris, who dropped back to sixth on the first lap after running wide while battling for the lead with Verstappen, was also decisive in making up for his earlier misfortune.
Norris ate into Piastri's lead through the second half of the race but the Australian kept him at arm's length.
