15:32 Bottas is matching the pace of the Ferraris now, so the gap is only 6.1s as he actually makes up some time by the end of lap 22. That's a personal best for Bottas, 4-5 tenths of a second quicker than the top two.
15:33 Lance Stroll has kissed the troublesome right-hander at the Swimming Pool. It was a delicate touch and shouldn't hamper the 13th place man.
15:33 So what's going on with Raikkonen? Vettel is one second down on him over the line, and Bottas has the gap down to 5.5s now to the leader. Time for the leader to respond.
15:34 Hamilton remains 10th and reporting that he's struggling with the rear tyres.
15:35 Bottas continues to take chunks of time out of the Ferraris, as Raikkonen approaches traffic.
15:35 Vettel is 1.0s behind Raikkonen now, the closest he's been since the start of the opening lap.
15:35 Vettel continues to bring the gap down - he's inside a second at 0.8s now. Raikkonen has closed up to Button, who is 19th.
15:36 "Come on, how close do I have to get?" says Raikkonen, who wants blue flags for Button. He's told Button is not being shown "solid blue" lights yet - which is the instruction that forces backmarkers to get out of the way immediately.
