Silverstone, England (Sports Network) - Mark Webber from Red Bull edged his teammate and defending Formula One world champion Sebastian Vettel to win the pole in Saturday's qualifying session for the British Grand Prix.

Webber, who won last year's British GP, turned a lap around the 3.667-mile (5.891-kilometer) Silverstone Circuit in one minute, 30.399 seconds to claim his second pole of the season. His fastest lap came before a light rain fell on the circuit in the closing minutes of the final qualifying stint.

"It was a very mixed session for all of us," Webber said. "It was important to make sure that every lap counted, because you never knew if it was going to be the one that did count for grid position."

Webber also outran Vettel for the pole in the May 22 Spanish Grand Prix. Red Bull has been perfect in qualifying so far this year, winning the pole in the first nine grand prix.

Vettel was the quickest in the final practice session, held earlier in the day. He qualified 0.32 seconds behind Webber.

"It was a difficult session with the conditions changing," Vettel said. "When it starts to rain here, it can vary in different parts of the circuit. It's quite difficult to see where it is wet or where it is fine."

Ferrari drivers Fernando Alonso and Felipe Massa qualified third and fourth, respectively. Jenson Button from McLaren took the fifth spot in front of his home crowd.

"I think it was the best qualifying for us this year, in terms of the gap to the pole position," Alonso said. "Silverstone is a circuit that's normally not our preference in terms of layout and characteristics and the high-speed corners. Being one-tenth [of a second] from the pole is good news for us."

Vettel currently holds a 77-point lead over Webber and Button.

Paul di Resta from Force India surprisingly qualified sixth, while Pastor Maldonado placed his Williams car seventh on the grid.

Sauber's Kamui Kobayashi will start eighth, and Nico Rosberg from Mercedes will roll off ninth.

The rain was a huge disadvantage for Lewis Hamilton, as the McLaren driver qualified 10th. Hamilton enters his home race 89 points behind Vettel.

Michael Schumacher from Mercedes failed to make it into Q3. Schumacher, the seven-time F1 champion, will start 13th in Sunday's British GP, which is scheduled to start at 8:00 a.m. (et).
