MONACO (AP) -- Formula One championship leader Sebastian Vettel secured his fifth pole of the season after posting the fastest time in Saturday's crash-marred qualifying session at the Monaco Grand Prix.
Vettel's fast lap of 1 minute, 13.556 seconds gave Red Bull its sixth straight pole, ahead of McLaren's Jenson Button and Vettel's teammate Mark Webber.
Webber took the pole at last week's Spanish Grand Prix, Vettel took the previous four poles and already leads McLaren's Lewis Hamilton overall by 41 points.
Ferrari's Fernando Alonso was quickest in the final practice Saturday morning, but dropped to fourth in qualifying.
Mexico's Sergio Perez was taken to the hospital after crashing his Sauber exiting the tunnel near the end of qualifying, one of three accidents during the session.
