Hamilton closes in on title after Japanese GP win

Suzuka, Japan - Lewis Hamilton romped to victory at the Japanese Grand Prix on Sunday to close in on a fourth world title after Sebastian Vettel retired with engine failure four laps in.

The Briton dominated from pole, steering his Mercedes to a crushing eighth win of the year, stretching his Formula 1 championship lead over Vettel to 59 points with just 100 left to play for.

Double podium finish for Red Bull

"Honestly I could only have dreamed of having this kind of gap," said Hamilton after holding off a late charge from Max Verstappen in Suzuka.

"The team has done a phenomenal job, they're just so meticulous so a big thank you to the guys."

As it happened: 2017 Japanese GP 

The Red Bulls of Verstappen -- who stunned Hamilton to win in Malaysia last week -- and Daniel Ricciardo secured a double podium for the second successive race.

Valtteri Bottas finished fourth in the second Mercedes with Kimi Raikkonen's Ferrari taking fifth and Esteban Ocon sixth for Force India.

Spark plug issue on Vettel's car

As Hamilton powered to his fourth victory in Japan, Vettel's title hopes suffered a potentially fatal blow with four races left after a nightmare start from the front row.

Ferrari mechanics worked frantically on the grid to fix a spark plug issue before lights out and Vettel was quickly complaining of a lack of power.

The German, who finished fourth in Malaysia and crashed from pole in Singapore before that, plummeted to sixth on the first lap before being told to retire the car as Hamilton roared away into the distance.

"It's just a pity in the two races with the reliability issues," said Vettel, who led the championship just six weeks ago.

"But now it's important to get some rest and give my all for the last four races and see what happens."

The warmer conditions were supposed to favour the Ferraris but Hamilton ruthlessly took a stranglehold on the 53-lap race, backing up his record-breaking pole performance on Saturday.

Verstappen raised pulses over the final two laps but ultimately his charge was too little too late to prevent a fourth successive Suzuka win for Mercedes.

Also in the points, Sergio Perez finished seventh for Force India ahead of the two Haas cars of Kevin Magnussen and Romain Grosjean with Felipe Massa holding off Fernando Alonso's McLaren to take 10th for Williams.
