Image source, Getty ImagesThere'll be smiles galore down at Red Bull after they laid down a marker to Mercedes in opening practice for the Singapore Grand Prix.
Max Verstappen topped the timesheet, with Daniel Ricciardo second quickest as Nico Rosberg crashed out and Lewis Hamilton finished fourth.
It would suggest Red Bull are primed to take the fight to Mercedes this weekend but, as ever, you can never write off the Silver Arrows...
Second practice gets under way at 14:30 BST, but we'll be powering up this live page again at 14:00.

Max Verstappen, in his last race weekend as an 18 year old, finishes quickest in first practice, pipping his Red Bull team-mate Daniel Ricciardo by five hundredths of a second.
Lewis Hamilton was fourth, 0.6s behind Verstappen but whereas the teenager set his time on ultrasofts, Hamilton's came on softs.

No time: Grosjean
Max Verstappen finishes quickest in first practice for the Singapore Grand Prix.

Would love to see F1 cars hammering it down the Bund but I'm not sure the rest of the city's streets would lend itself to a decent street circuit.

My gut instinct is there is a lot more to come from Mercedes but there is cause for optimism that Red Bull can give them something to think about this weekend. What we are again seeing here is an indication of how Red Bull have leapfrogged Ferrari.
Lewis Hamilton runs wide at Turn One but rejoins the track with minimum of fuss.
He's fourth with five minutes to go. Max Verstappen leads with Daniel Ricciardo second and Sebastian Vettel third.

Nico Rosberg is back in the pits minus the front wing and with a puncture on his front left.
Crash for Nico Rosberg! He slams his Mercedes nose first into the barrier at Turn 18. He's OK and able to reverse and limp home.
Jenson Button is out on the circuit and has been for a while now after a problem early doors saw him come to a halt.
He is P16 with 1:49.615 and is not completely happy with how his McLaren is handling at the moment, saying second and third gear "feel very poor on the throttle".
It's a photographer's dream in Singapore now with the sun having set and the moon taking its place in the sky. As ever, it looks absolutely stunning. Only Hong Kong, for me, could rival Singapore for its beauty as a possible night race venue. Have always wanted to see an F1 race there.

He's currently 14th quickest in first practice.
Max Verstappen is back on top after a 1:45.823, so the top of the order with just under 30 minutes to go looks like:
1) Verstappen 2) Ricciardo 3) Vettel 4) Hamilton 5) Rosberg 6) Sainz
