locked in an intense fight for the Formula One championship, and preparing for his 200th career start, Nico Rosberg pulled out a stunning lap to snatch pole position for the Singapore Grand Prix on Saturday.
Rosberg, who trails championship leader and Mercedes teammate lewis Hamilton by two points, put himself in the best possible position for a third consecutive race victory by qualifying more than half a second faster than Red Bull's Daniel Ricciardo in second.
"For my 200th appearance, definitely one of my top three laps ever," Rosberg said. "It wasn't clear in qualifying how we would stack up against Red Bull so I really had to give it everything and pull it out of the bag, which is cool."
Hamilton, who struggled relative to his teammate throughout practice at the Marina Bay street circuit, qualified third, seven-tenths of a second off Rosberg's time.
Red Bull's Max Verstappen qualified fourth.
Ferrari's Kimi Raikkonen was fifth, and teammate Sebastian Vettel will start last in Sunday's race after his car had an anti-roll bar failure in the Q1 session.
Though Rosberg's time was stunning, Red Bull retained confidence about its prospects of a race victory. Both Ricciardo and Verstappen will start the race on harder tires than Mercedes, so their first stint before pitting should be longer. That will allow them greater flexibility of strategy at a venue that has had safety car periods in all of its previous races.
Toro Rosso's Carlos Sainz Jr. qualified sixth followed by teammate Daniil Kvyat in seventh. Force India's Nico Hulkenberg and Sergio Perez qualified eighth and 10th, separated by Mclaren's Fernando Alonso.
Rosberg's 29th career pole took him level with the great Juan Manuel Fangio on the all-time list, and provided a fillip for his confidence on a track where he has never shown his best. This was his first pole in Singapore, where his best finish was second back in 2008, when he was with Williams.
He paid credit to his team for being able to diagnose and overcome the problems that saw the team perform relatively poorly in qualifying here last year.
