The first outing of the Miami Grand Prix is starting, and Ferrari looks to continue their successful streak starting from Bahrain and Australia into Miami. Ferrari's two drivers Charles Leclerc - who is leading the Drivers' Championship coming into the race - and Carlos Sainz Jr. lock out the first two rows of the grid. In the race, Verstappen immediately takes second from Sainz, and would take the lead by the ninth lap. Soon, McLaren's Lando Norris makes contact with Pierre Gasly of AlphaTauri, bringing out the safety car. Leclerc's old tires soon give him a disadvantage, which Verstappen exploits in his first victory in Miami. Leclerc finishes second ahead of his teammate.
As the season continues, Ferrari continues to make errors that end up costing their drivers the win; in Monaco, Leclerc leads the race as Sainz is brought in - but Leclerc, having been told to come in too, follows Sainz into the pits - only being told to stay out after he had already came in for his stop - handing Red Bull's Sergio Pérez the victory as Leclerc finishes fourth; in Baku, both Ferraris - Leclerc leading - retire due to mechanical failure with Verstappen winning; and in Canada, both Ferraris stay out again and are inconvenienced by their old rubber, handing Verstappen the win once again.
At a rainy Silverstone qualification, Sainz scores his first pole position in his career, and Leclerc, having spun earlier in quali, takes third. The race starts with a big crash for Zhou Guanyu, red-flagging the race. The race starts with Sainz, having retained his grid position, getting a good start; by lap ten, Sainz continues to control the field, but makes an error, allowing Verstappen to take the lead. However, the Red Bull driver reports a puncture and pits, allowing Sainz to take the lead again with Leclerc behind. Soon, the Ferrari pit wall tells Sainz to give the position to Leclerc as Esteban Ocon retires due to mechanical issues, bringing out a safety car. As Leclerc is told to stay out on his old tires, Sainz is brought in for fresh rubber. The race restarts and Sainz overtakes his struggling teammate for first, going on to win his first race in his career.
