Esteban Ocon was first on track and first to set a lap, posting a 1m31.125s on the medium compound which proved to be enough for an early edge over Lewis Hamilton on softs.
The Ferrari duo then set their first laps of the session on softs and, of the two, Carlos Sainz posted the faster time with a 1m30.748s, three tenths clear of Charles Leclerc's first lap as the Monegasque recovered from his FP2 crash on Friday.
