Free Practice 1 in Singapore was led by Max Verstappen, as Red Bull’s expected pace managed to shine through round the lengthy street circuit. Lewis Hamilton ran the halo device early on, and finished the morning fourth, whilst Rosberg was slightly down on his teammate but more down on luck – he crashed into the wall and damaged his front wing. Jenson Button also stopped out on track after just three minutes of the session, causing a virtual safety car thanks to a fuel system issue.
