2014 Bahrain Grand Prix Sunday - Bahrain GP

It's looking like minor points for Red Bull. Vettel is 10.6s behind Button in ninth, and Ricciardo is just behind him in 10th.

Massa is right up behind Bottas in the battle for third. Perez is edging ever closer though, as is Hulkenberg. This could be a fascinating finish.

Hulkenberg blasts past Alonso and duly takes sixth. Next on his radar is Perez, 3.6s up the road.

Alonso will now look in his mirrors and await an attack from Button, who is 2.5s behind.

Ricciardo wastes no time in passing Magnussen too.

Massa tells Williams: "we need a better strategy".

Ricciardo goes around the outside of Raikkonen to take 12th place.

Personal best lap for Perez in fifth as he hunts down the Martini-liveried cars in front.

Alonso is sixth, but has an incredibly quick Hulkenberg closing fast.

Vettel passes both Magnussen and Maldonado to get into 11th.

EDD STRAW: "Pace on the medium tyre is certainly better than expected. If you look at Rosberg compared to Hamilton, the laptime gap has generally been around the 2-3 tenths level for much of their stints. This will certainly tip the dial more towards a two-stopper for some in the field."

Twenty laps remaining, and the Williams are running third and fourth again.

Ericsson had reported that he was losing power and was ordered to immediately stop his Caterham.

Hamilton's lead is almost up to 10s now at the front.

Hulkenberg's pitstop brings him out behind the Perez/Alonso battle.

Ericsson parks his Caterham at the trackside.

This a low key race for Magnussen, who is told he's racing Maldonado (who seems to be on course for one stop less) for position. Eleventh position, that is.

Button joins the Force India in the pitlane - this battle will rage until the finish.

Hulkenberg pits from third.

But Perez pretty much immediately repasses the Ferrari.

Perez has rejoined behind Alonso.

Button's got within 2.5s of Hulkenberg in the fight for third now.

Massa now passes Ricciardo.

Perez and Vettel both pit. Here we go.

"OK Lewis, you're safe on fuel, so no more lift and coast," Mercedes tells Hamilton, who replies "I heard you, man, I'm looking after my tyres."

Bottas grabs seventh from Ricciardo into Turn 1 as Raikkonen makes his second pitstop with 23 laps to go.

Vettel, who is running a lonely sixth, is told to "hang in there, we need a few more laps."

Hulkenberg's dropped out of DRS range from Perez now. That battle's quietened down.

Rosberg is 8.5s behind Hamilton now.

Massa flies past Raikkonen on the back straight.

Chilton tells Marussia that the right hand side of his cockpit is getting hot.

Bottas instantly gets onto Ricciardo's tail. Raikkonen will soon have Massa right behind him.

That looks like a timing error - Button's first sector is now absolutely fine!

Bottas makes it past Raikkonen on the back straight. Now he chases Ricciardo.

Button's had a rather sluggish first sector - the middle sector's fine, so something must have happened.

Bottas has caught back up and trying down the outside into the downhill Turn 8.

Ricciardo finally squeezes past Raikkonen for seventh.

Hulkenberg's edging ever closer to the back of his team-mate, and must be about to launch an attack.

They need to be careful though, because Button's nibbling away at the gap to the Force Indias - though Vettel is another 5s further back.

Massa is now bearing down on the Raikkonen, Ricciardo, Bottas fight too.

We've eased past halfway now, and it's going to be fascinating to see how the strategy choices play out at the front.

Rosberg's been told the difference between the compounds is not as much as first thought. That means a late charge on the softs might not be as profitable as first though.

Now it's Ricciardo who is all over Raikkonen's rear wing again.

The Williams very nearly ploughed into the back of the Ferrari. "What is he doing??" Bottas asks over the radio.
