McLaren's Lewis Hamilton was perfectly placed to extend his Formula One championship lead after seizing pole position for the Belgian Grand Prix on Saturday. The 23-year-old Briton will start Sunday's race with Ferrari's Brazilian Felipe Massa, his main title rival, alongside on the front row. Ferrari's world champion Kimi Raikkonen, who has won the last three Belgian Grands Prix at his favourite circuit, qualified fourth with fellow-Finn Heikki Kovalainen third for McLaren. The pole position, with a fastest lap of one minute 47.338 seconds on a damp and overcast afternoon in the Ardennes forests, was Hamilton's 11th of his 30 race career and fifth of the season. Hamilton leads Massa by six points in the championship with six races remaining, while Raikkonen is a further seven points adrift and struggling to end a winless streak dating back to the end of April. Germany's Nick Heidfeld, under pressure from BMW-Sauber to raise his game, outqualified Polish teammate Robert Kubica for only the second time this season with fifth place on the starting grid. Renault's double world champion Fernando Alonso, maintaining his 100 percent record of outqualifying Brazilian rookie teammate Nelson Piquet, joined Heidfeld on the third row with Australian Mark Webber seventh for Red Bull. Kubica was eighth with the two Toro Rossos of Frenchman Sebastien Bourdais, who was surprisingly quickest after the first session, and young German Sebastian Vettel filling the fifth row.
