SINGAPORE (Reuters) - Sebastian Vettel moved a step closer to clinching his second successive Formula One title in Singapore after securing Red Bull's 14th pole position in as many races this season. Vettel, who could be only a day away from becoming the sport's youngest double world champion if results go his way, lapped the floodlit Marina Bay Circuit in one minute 44.381 seconds to edge out team mate Mark Webber by 0.351. McLaren's Jenson Button was third fastest in Saturday's qualifying with a time of 1:44.804. The pole position was Red Bull's 15th in a row stretching back to the final race of last season at Abu Dhabi and never looked in doubt once Vettel got a clear track following a frustrating final free practice earlier on Saturday. McLaren's Lewis Hamilton will start fourth on the grid after an evening deflated by a puncture in the second qualifying session. A refuelling problem then meant he was unable to do more than one quick lap in the last session. The Ferraris of Fernando Alonso and Felipe Massa will fill the third row of the grid, ahead of the Mercedes duo of Nico Rosberg and Michael Schumacher. Qualifying was briefly red flagged with nine minutes remaining of the second session when Sauber's Kamui Kobayashi went airborne after hitting the kerb at speed through the turn 10 chicane and crashed into the wall. Vettel, 24, has a 112 point advantage in the championship and will take the title on Sunday with five races remaining if he can extend that lead by a further 13 points. Alonso is currently second overall, with Webber and Button both 117 points adrift of Vettel.
