Ex-NFL player Jonathan Martin detained by police over social media post
The post, which was uploaded to the Instagram story of Jonathan Martin '08, featured a shotgun surrounded by shell casings. It was not immediately clear whether Martin posted the photo himself and he was not under arrest Friday afternoon.
"With the weather conditions being up and down, and the loss of track time we had yesterday, it made sense to keep Valtteri in the vehicle this afternoon", said the Briton in a team review of the day's action. "It is handling good so far". You can always improve it but in terms of lap times we are doing well, so we don't really have big issues.
"Last year I did not perform on the level I should have and I learned a lot from that".
McLaren's Stoffel Vandoorne was third fastest on the day, just 0.001secs quicker than Verstappen, but the Belgian was using the fastest hyper-soft tyre, which is three grades softer than the soft used by Vettel, so the time can not be directly compared.

I think like this it works well. I don't know yet but in terms of general operation it's been very smooth so it's good to come here, switch on the auto and be able to run.
In contrast to Hamilton's limited running, Bottas has already racked up 152 laps of testing, the equivalent of two and a half race distances, after he was given an entire day behind the wheel on Tuesday.
Although early test runs aren't the be all and end all, Red Bull's new vehicle looks to be pretty fast. Toro Rosso will also be pleased with the 82 laps completed by Pierre Gasly, marking another day of Honda not being bad (a surprise, I know).
