Sebastian Vettel led home a Red Bull 1-2 in the Belgian Grand Prix here on Sunday to tighten his grip on the 2011 drivers' title.
The German defending champion - recording his 17th career win - was followed across the line by his Australian teammate Mark Webber, with McLaren's Jenson Button and Fernando Alonso of Ferrari in third and fourth.
Michael Schumacher, on his 20th anniversary since his Formula One debut, came in fifth having started from the back of the grid, while 2008 champion Lewis Hamilton failed to finish after a crash.
Vettel moved up to 259 points in the standings, with Webber in second on 167, ten points clear of third-placed Alonso.
Button moved into fourth on 149, three ahead of Hamilton.
