Lewis Hamilton is already on the back foot at the Miami Grand Prix, with his Ferrari struggles continuing in an FP1 session ended by a red flag.
Since moving to Ferrari ahead of the 2025 season Hamilton has struggled to get to grips with his new machinery and could only put his SF-25 P13 ahead of sprint qualifying later today.
Hamilton's team-mate Charles Leclerc, meanwhile, ended the session in P2, three and a half tenths behind session leader Oscar Piastri.
Max Verstappen, Carlos Sainz and Alex Albon rounded out the top five in FP1, whilst Lando Norris was unable to set a representative lap time on the soft tire prior to the red flag coming out.
The Haas of Ollie Bearman ended the session prematurely after spinning out and crashing into the wall at Turn 12 with just over four minutes of the session remaining.
With vehicles having to come onto the track and retrieve his car, the red flag remained as the clock ticked down to zero.
