51st career pole position for Sebastian Vettel
Red Bull's Sebastian Vettel took pole for the Singapore Grand Prix after some self-imposed anxious moments as his rivals came close to his time.
Vettel has dominated all weekend under the lights of the demanding Marina Bay circuit at Formula 1's night race, but sat out the final minutes of the session.
He thought he had done enough after a fast early run and watched as Mercedes' Nico Rosberg closed to within 0.091secs.
Vettel's title rival Fernando Alonso could manage only seventh in his Ferrari.
Lotus's Romain Grosjean took third, ahead of Red Bull's Mark Webber and Mercedes driver Lewis Hamilton.
