Kimi Raikkonen won the Belgian Grand Prix for the third time in a row yesterday, leading a Ferrari one-two to revive his title challenge.

Brazilian Felipe Massa finished second, 4.6 seconds behind the Finn, with McLaren's double world champion Fernando Alonso third to cut teammate Lewis Hamilton's overall lead to two points.

With three races remaining, 22-year-old British rookie Hamilton has 97 points to Spaniard Alonso's 95. Raikkonen, celebrating his 13th career win and fourth of the year, is on 84 with Massa taking his tally to 77.

If any proof were needed that the gloves were off between the McLaren drivers, whose team was stripped of all its 2007 constructors' points and fined US$100 million on Thursday for its part in a spy controversy, Alonso forced Hamilton off the track coming out of the first corner.

Ferrari mathematically clinched the Formula One constructors' title, subject to any appeal from McLaren against its penalty in the next week.

Ferrari, celebrating its third one-two of the year and past five races, now has 161 points. Second-placed BMW-Sauber is on 90 with 54 remaining to be won. McLaren would have had 177.

Germany's Nick Heidfeld was fifth for BMW Sauber with compatriot Nico Rosberg sixth for Williams.

Australian Mark Webber collected two points for Red Bull while Finland's Heikki Kovalainen wrapped up the scorers with eighth place for Renault.
