Lewis Hamilton [Images] captured his second pole position in a row at the US Grand Prix on Saturday to put more pressure on McLaren team mate Fernando Alonso [Images].

The British rookie, who celebrated his first Formula One pole in Canada [Images] last weekend, pipped double world champion Alonso in final qualifying on another sizzling hot day at the Indianapolis Motor Speedway.

Sunday's race will be the third in a row with an all-McLaren front row. Championship leader Hamilton, the winner in Montreal, leads Alonso by eight points in the championship after six races.

After struggling in the last two races, Ferrari [Images] returned to form by sweeping the second row with Brazil's [Images] Felipe Massa [Images] clocking the third fastest effort followed by Finland's Kimi Raikkonen [Images].

German teenager Sebastian Vettel, who will make his Formula One race debut on Sunday in place of Robert Kubica after the Pole failed a fitness test following his big crash in Canada, will start a superb seventh for BMW Sauber.
