HIGHLIGHTS: Watch the best action from the opening practice session of the Russian GP
The on-track action got underway ahead of this weekend's Russian Grand Prix on Friday morning at Sochi – and there was plenty going on as the drivers got their first laps of the circuit under their belts.
Although there was a familiar name at the top of the time sheets with Valterri Bottas posting the quickest time for Mercedes, his team mate Lewis Hamilton ended up down in 19th after a session hampered by lock-ups and flat spots on his tyres.
Elsewhere there were two crashes in the session with both McLaren's Carlos Sainz and Williams' Nicholas Latifi ending up in the barriers minus their rear wings, while Romain Grosjean also spun in his Haas, though he kept it out of the wall.
