Lewis Hamilton topped the time board, despite sitting out the final 15 minutes. Mercedes team-mate Nico Rosberg came in behind him.
The Mercedes pair were the only drivers to exhibit the super soft tyres in that first session.
But the big news was Daniel Ricciardo's crash at Turn 15, which saw his Red Bull hoisted off the track like a yo-yo.
Will Red Bull get the Pritt Stick out in time to glue together the Australian's car for FP?

Charlie's not fibbing. We've just seen a fella out there with a soldering iron, sparks flying like it's the 4th of July.
Can you imagine getting on a plane 10 minutes after a bloke was out there soldering the wing?
Have fun, boys.

FIA F1 director Charlie Whiting tells Sky Sports FP2 will start on time.
"Small bolts had come loose at the end of the kerbs on Turn Six and 12. So we've taken the bolts out and welded the kerbs to each other. Everything's new, they've done the best they could and we just needed to do a bit of fixing."

Image source, Rex FeaturesSafety concerns have emerged about the new circuit in Baku after a series of cuts to tyres caused by kerbs.
There are doubts about whether Friday’s second practice session, scheduled for 1400 BST, can go ahead as officials grapple with a solution.
Most teams suffered cuts to the left rear tyres of their cars in the first session earlier on Friday and a qualifying session for the GP2 series had to be cancelled.
Teams say it is not clear exactly which kerbs are causing the problem.

Any chance we can just ask all the drivers to completely avoid the kerbs? No?
