'Over from the start': Daniel Ricciardo wrecked in fresh Renault 'disaster'

Daniel Ricciardo admits his Russian Grand Prix hopes were wrecked by damage caused by a first-lap incident which eventually forced his Renault car to retire early on Sunday.

The Australian, who had qualified in 10th place for the race in Sochi, was involved in a three-car clash with Haas driver Romain Grosjean and Alfa Romeo's Antonio Giovinazzi at turn four which left him with a rear-left puncture and aerodynamic and balance problems which greatly hindered his efforts.

He was eventually retired from the race by his team on lap 25 having been unable to make inroads from the back of the field.

"Unfortunately, our race was pretty much over from the start," Ricciardo told his team's website.

"I had too much damage on the car to carry on, which is a shame.

"I got hit and had a puncture and damage to the floor. I'll look at it with the perspective that if I qualify higher up the grid then I'm less likely to be in the bad stuff.

"I'll take responsibility for that, but in terms of the accident, I was just a passenger."

World champion Lewis Hamilton won the race ahead of teammate and closest rival Valtteri Bottas in a surprise Mercedes one-two.

Ricciardo's teammate, Nico Hulkenberg, crossed the line in tenth place position, at least salvaging a point for Renault.

Hamilton ends Ferrari run

Hamilton snatched victory in a surprise Mercedes one-two after Ferrari argued over team orders and were undone by a virtual safety car.

Hamilton also banked a bonus point for the fastest lap of the race to stretch his lead to 73 points over teammate and closest rival Bottas, who finished second, with five rounds remaining.

Ferrari's Charles Leclerc finished third after an early radio controversy with Sebastian Vettel, whose retirement on the 28th of 53 laps brought out the virtual safety car that ironically cemented Hamilton's lead.

Mercedes's victory was their sixth in a row in Sochi, the team having won every Russian Grand Prix since the first in 2014.

The victory was the 82nd of Hamilton's career, and ninth of the season, leaving him nine short of Michael Schumacher's all-time record of 91.

"It feels like a long time coming, it feels like the first time as well," said Hamilton, now closer than ever to a sixth title, of his first win since Hungary on the eve of the August break.

"It's just incredible to have this result today, considering how quick they (Ferrari) were off the start. Just keeping up with them was an incredibly hard task.

"Honestly I try not to think too much about the championship. One race at a time and one step at a time...one foot in front of the other. We don't want to stumble."

Ferrari had arrived in Sochi after a hat-trick of wins and looking set for another triumph after Leclerc seized pole position for the fourth race in a row by a comfortable margin.

But the Italians tripped themselves up with a strategy that involved Leclerc allowing Vettel, starting in third place, to slipstream the Monegasque off the start and take the lead into turn two.

The deal was for the German to hand back the place once Ferrari had settled into a one-two formation but instead Vettel began banging in a series of fastest laps to Leclerc's consternation.

"Sebastian will let you by next lap," the 21-year-old was told over the radio on lap four.

But Vettel, a four-time world champion, refused to ease off and said Leclerc would need to close a gap of some 1.3 seconds to make that possible.

Leclerc was already smarting after being undone in Singapore by a strategy that worked in Vettel's favour, with the team radio again crackling with anger as the youngster vented his feelings.

"You put me behind. I respected everything," he said as it became clear Vettel, winner in Singapore after more than a year off the top of the podium, was clearly faster and had no intention of easing off.

"I respected. I gave him the slipstream," he added later.

Leclerc pitted from second place on lap 23 and came back out in fourth. Vettel made his stop three laps later, trading places with Leclerc while Hamilton led.

Two laps later Vettel coasted to a halt by the side of the track, and the virtual safety car period gave Hamilton the chance to take a free pitstop and come back out ahead of Leclerc.

The Monegasque made another pitstop on lap 31 when the real safety car was deployed after George Russell crashed in his Williams, resuming in third and unable to pass Bottas.
