Suzuka, Japan - Lewis Hamilton limbered up for this weekend's Japanese Grand Prix by going fastest in Friday's first free practice almost half-a-second quicker than Mercedes team-mate Valtteri Bottas.
The Briton, who controversially took his eighth chequered flag of the season in Russia last week after Mercedes ordered Bottas to let him through, clocked one minute, 28.691 seconds on super-soft tyres at Suzuka.
Ferrari's Sebastian Vettel, now trailing Hamilton by 50 points with only five races left this season, was fifth fastest on the timesheets 0.994 seconds back.
Red Bull's Daniel Ricciardo set the third fastest lap with Ferarri's Kimi Raikkonen fourth quickest.
Hamilton, who whizzed into the pits on his scooter 10 minutes after the start of the morning's free practice, survived a hairy moment early on, reacting superbly to avoid smashing into Pierre Gasly's dawdling Toro Rosso on entry to the chicane.
