Kimi Raikkonen has topped the second practice session in Singapore, beating Lewis Hamilton to the fastest time by just 0.011s. The Finn's fastest lap was a 1:38.699, with the gap to the Red Bull's behind indicating that it will be a two-horse fight this weekend between Ferrari and Mercedes.
The Red Bull duo finished in third and fourth, with Max Verstappen leading Daniel Ricciardo. Verstappen was over half a second down on Raikkonen, which will disappoint the energy drink squad, as it was hoping to be closer than usual this weekend to Ferrari and Mercedes.
Valtteri Bottas was fifth, while Sebastian Vettel didn't complete his qualifying simulation lap. The German hit the wall at Turn 21 and immediately returned to the pitlane, where Ferrari found a radiator leak that put an end to his session.
Vettel finished in ninth place, behind Carlos Sainz, Romain Grosjean and Fernando Alonso, who all finished in sixth, seventh and eighth respectively. Nico Hulkenberg made it two Renault's inside the top ten, after setting the tenth fastest time.
Sergio Perez failed to get inside the top ten, missing out by just a tenth of a second. He was ahead of Marcus Ericsson and teammate Esteban Ocon. After crashing in FP1, Charles Leclerc had a smoother session and ended in fourteenth.
Kevin Magnussen couldn't match the pace of his teammate Grosjean as he could only manage fifteenth. Stoffel Vandoorne found some pace after being the slowest driver in the opening practice session and ended in sixteenth.
The two Toro Rosso's followed with Brendon Hartley going one-tenth quicker than teammate Pierre Gasly. Williams rounded out the time sheets and look to be in for another tricky weekend, with Lance Stroll heading teammate Sergey Sirotkin.
