Team Summary:
The opening Friday practice would see a wet track as drivers started to come out for their installation laps using the full wet tyre. Amongst them would be both Williams drivers who would pit after single laps. Drivers coming out later were on the intermediate tyre and with twenty minutes of the session completed no times had been set. It was expected that the wet track would remain for the rest of Friday. Ricciardo would set the first time with a 1m:55.266 but Verstappen would move ahead with a 1m:53.644 with both on the intermediate tyre. But Ricciardo would set a 1m:51.512 to again be quickest. With fifty five minutes remaining both Williams drivers were back out running on the intermediate tyre.

Bottas was now fastest using the intermediate tyre with a 1m:48.806 followed by Ricciardo, Verstappen, Alonso, Sainz and Raikkonen in sixth. Everyone was on the intermediate tyre as Raikkonen went fourth but Sainz would take this spot. Ericsson was now fifth followed by Raikkonen, Alonso, Leclerc, Norris and Vettel tenth. The session would be red flagged as a result of drivers dragging gravel onto the circuit when they went off. The session would restart with just under forty minutes remaining with both Williams drivers returning. Hamilton would move up to third behind Ricciardo. Verstappen would jump up to second. Hamilton would go quickest with a 1m:47.502 to be ahead of Bottas. Vettel would move up to sixth followed by Grosjean and Sainz. Leclerc was now 10th while the Williams drivers had both pitted and were currently 17th and 19th.

With fifteen minutes remaining the track would empty but both Williams cars would return running on the used intermediate tyres. With the end of the session the top ten would be Hamilton, Bottas, Verstappen, Ricciardo, Vettel, Raikkonen, Sainz, Grosjean, Leclerc and Ericsson tenth. For Williams their drivers would finish the session in 15th and 19th with Sergey ahead of Lance. Not much could be read into this result as the track conditions were changeable but Sergey certainly needs to show an improvement as he no doubt chases the second seat at Williams for 2019.
