Magnussen returns to the pits, having completed 101 laps. He's the first man to hit a century of laps this afternoon.
Raikkonen looks likely to join Magnussen in that club shortly, too. He's just ticked over to lap 98.
The Iceman is out on track with Verstappen, Ocon and Palmer.
Raikkonen has started his 100th lap. Edge of the seat stuff in the media centre.
@openthedrs, Hamilton went out this morning, Bottas in the afternoon. 10 cars, 11 drivers.
15 minutes left and Verstappen, Magnussen, Ocon, Kvyat, Bottas and Giovinazzi are on track at the moment.
Nobody is setting the timing screens alight at the moment, with the majority on longer runs and lapping in the 1:24s.
@Sian Yep, pretty good, but remember the Ferrari and Mercedes have set times in the 1:20s.
Bottas heads out again. He's on course to clock up 100 laps in just one afternoon!
The most laps for a single driver is 116 for Magnussen. The Mercedes drivers combined have completed 165.
And that's the end of the session. The chequered flag comes out as Bottas crosses the line for the 100th time.
Final times and a report coming your way.
