Hamilton needs Suzuka F1 hat-trick

Lewis Hamilton will have to dig deep to overcome the heartbreak of Malaysia as he heads into Sunday's Formula One Japanese Grand Prix, needing a third straight win at the Suzuka circuit to revive his flagging title prospects.

The triple world champion's hopes of claiming a fourth title were dealt a heavy blow on Sunday at Sepang, forced to retire with a blown engine while leading comfortably with 16 laps remaining.

That allowed Australian Daniel Ricciardo to score his first win of the year ahead of Red Bull teammate Max Verstappen in the team's first one-two finish since the 2013 Brazilian GP.

Had Hamilton won, scoring a landmark 50th career victory, he would have vaulted back to the top of the overall standings ahead of Mercedes teammate Nico Rosberg.

He needs to bridge a 23-point gap to the German, who finished third in Malaysia after being spun around and dropped to the back of the field by Ferrari's Sebastian Vettel at the start.

Vettel will drop three grid places in Japan as punishment.

"It's not how you fall, it's how you get back up," Hamilton told reporters.

"If I can find strength from within to be able to come to these next races and perform like I've performed this weekend then, providing the car holds together, good things will come."

Reliability issues have plagued Hamilton's 2016 campaign, prompting him to hint at a conspiracy.

"Someone doesn't want me to win this year. My question is to Mercedes. We have so many engines made but mine are the only ones failing this year," he told BBC Radio 5 Live.

"Someone needs to give me some answers because this is not acceptable. We are fighting for the championship and only my engines are failing. It does not sit right with me."

Hamilton turned a deficit of 43 points to Rosberg earlier in the season into a 19-point advantage over the German with six wins from seven races, but is running out of time to mount another comeback with only five races left.

Rosberg, whose Finnish father Keke took the 1982 title, is keeping his focus squarely on Japan.

"I'm quite liking my approach of just seeing it as a weekend-on-a-weekend basis so don't have such thoughts and just accepting the way it went today," he said.

"Next is Suzuka where I want to try and win again."

Mercedes can win the constructors' championship on Sunday for the third year in a row.
