With that we'll call time on this live text coverage of Bahrain GP practice. Final practice gets under way at 12:30pm GMT tomorrow with qualifying at 4pm GMT. Remember, qualifying is on Friday afternoon and the race is at 3pm GMT on Saturday. Until then, go well!
Mercedes on top with Red Bull struggling... we'll see how accurate that'll be come this time tomorrow and Saturday. Now it is time to crunch the numbers and come up with the answers.
So, a Mercedes 1-2 to end FP2. Nobody would've told you that was going to happen at the start of the day. Has Mercedes turned up its engines more than the rest at this point of the weekend? We'll probably find out the truth this time tomorrow.
Tsunoda locks up into Turn 1 to dampen his run on these softs. Verstappen, Russell and Alonso are lapping in the high 1m36s with everyone else in the 1m37s or 1m38 region. But again, fuel loads and engine modes are largely unknown.
Norris is spending his race run tucked up behind Ocon's Alpine. It isn't entirely clear why but at least he's getting a good feel for his car in dirty air.
The lap times coming in are also reflecting the race run feel too. So, Norris didn't get a clean quali lap in at all in FP2, as he is bottom of the times and 2.2s off the pace. The rest, minus the Red Bulls, are close enough to where we would've predicted.
That looks to be it for the qualifying runs, as most drivers return for a stint on used softs and appear to be full of fuel. This is normally when everyone starts a race sim so in terms of outright lap time, that should be your lot.
Meanwhile Russell makes it a Mercedes 1-2 as he goes second with a 1m30.580s. Both Mercedes are running very low to the ground with a lot of sparks coming off the floor.
Verstappen chips away at his personal best in this session to go third with a 1m31.161s. He's still got four-tenths to find to catch Hamilton but it is early days yet.
Almost everyone has pitted from their first runs, and at the bottom of the times is all the medium-shod runners - including the top four from FP1 who set their times on softs earlier.
Fuel loads, engine modes, blah blah blah. Almost nobody will be running full beans and with a light car until qualifying, but this isn't the order we would've expected going on testing.
Just like FP1, it is pretty blowy out on the track and remarkably chilly compared to what we're used to coming to Bahrain. Or, a British summer night, to give it an accurate description.
Alonso pops up to second with a 1m31.035s to go within a quarter of a second of Hamilton's leading effort. Verstappen has belatedly joined the fun and is on his out-lap.
TV replays prove our suspicions were correct with Bottas, he did just roll over the pit exit line while he prepared for a practice start. The pit exit lights turned green a few seconds later and then he got going. At most, that will probably be a reprimand for the Finn.
There is a pretty even split between those on softs and those on mediums at the start of FP2. Still no sign of Verstappen, Russell and either Aston Martin.
