SEPANG, Malaysia -- Heavy rain halted proceedings for much of FP1 in Malaysia before Max Verstappen ensured Red Bull would finish the session on the top of the timesheets.
15 minutes before FP1 began, light rain started to fall on the Sepang International Circuit but it quickly intensified forcing race control to delay the start of the session. For 30 minutes the only track action fans were treated to was that of the Mercedes AMG Safety Car.
When the pit exit finally opened it was Fernando Alonso and the Ferraris of Sebastian Vettel and Kimi Raikkonen who first ventured onto the track.
