Hamilton wins after overtaking Bottas at start - Mercedes' 5th one-two victory in a row
Vettel damages tyres challenging for lead at start
Norris and Stroll out after collision
Lap 21/66
Max Verstappen comes in but goes back out on the red softs. That means he will have to pit again later on for a late onslaught. No move so far from Mercedes, with Hamilton going even faster to move seven seconds ahead.
Vettel is the only one of the top 13 to be on the mediums and not the softs.
Lap 20/66
The Ferrari mechanics sprint out, each holding a medium tyre. Sebastian Vettel finally gets his wish. A bit of a slow stop.
He went in at fifth position and comes out at 10th. Ouch.

Vettel: "Do you have a gap?"
Engineer: "No not yet."
Vettel: "You should find one then, I don't care if there's traffic. Pit me when you can."

Lap 19/66
Race leader, fastest man on track. It's all Lewis Hamilton.

Lap 18/66
Vettel's sounding a bit stroppy over the team radio, wanting to get rid of those tyres that he himself wrecked with an ambitious attempt to take the race lead on the first lap.
It didn't work out too well, but at least he gave it a go. "Pit me when you can," is him pleading to come in.

All the top 10 are wearing the soft tyres.

Haas could be zooming up this table by the end of the day. Mercedes currently heading for a one-two finish again. Something familiar about that.

Haas are on course for best of the rest title and a good points haul. Romain Grosjean seventh and Kevin Magnussen eighth, just as they started.

There we go, Ferrari may have done it a few laps late, but Charles Leclerc overtakes his team-mate.
Lap 13/66
The orange-clad Max Verstappen fans are in Spain in great numbers. But, not for the first time this season, it's looking a bit lonely for the Dutchman. Three seconds off Bottas in second and five clear of the fourth-placed man.
That is now Charles Leclerc as Sebastian Vettel, on the damaged tyres, moves over to let his team-mate through. Why they didn't do that a couple of laps earlier? Who knows?

The big climber is Nico Hulkenberg so far. He's advanced five places after starting from the pits. Lando Norris has dropped six spots after going wide early on.
Kayleigh: Who’s going to have their race ruined by Ferrari’s inability to work out decent pit strategies? Find out on this weeks episode of Ferrari Don’t Know What They’re Doing!
Stewart: "Charles is faster than you. Can you confirm you understand this message."
Andrew Ives: @danielricciardo must be feeling pretty sick down in 12th miles behind the Red Bull. Brave move to @RenaultF1Team but he must be regretting it every lap.
Lap 11/66
Charles Leclerc attacks Sebastian Vettel. No talk of being held back by his team. Leclerc weaves left, weaves right, but there is no way through. We spoke of two Mercedes potentially taking each other out? What if the Ferraris do that?

We have an interesting situation at Ferrari: Vettel flat spotted his tyres, and Charles Leclerc is within a second of Vettel - he's done the fastest first sector and he's now being held up by his team-mate.
In China, they were quick to swap positions, so will they do so today?

This is how it stands at the moment. Lewis Hamilton will jump back to the top as long as he finishes ahead of Valtteri Bottas.
