Rubens Barrichello won the pole for his hometown Brazilian Grand Prix in Sao Paulo in a chaotic qualifying session that was affected by heavy rain. He is the only title contender who will start in the top 10 today for the race.

Brawn GP teammate and Formula One championship leader Jenson Button will start 14th and Red Bull's Sebastian Vettel in 16th. Both drivers struggled in a qualifying session that was interrupted twice by red flags and delayed several times because of treacherous track conditions yesterday.

Barrichello clocked 1 minute, 19.576 seconds on the 2.6-mile Interlagos track, edging Red Bull's Mark Webber and Force India's Adrian Sutil.

Kyle Busch shrugged off walking pneumonia to dominate the Nationwide Series race at Concord, N.C., late Friday night, picking up his seventh victory of the year to extend his points lead over Carl Edwards with four races remaining. Mike Bliss was second, followed by Dave Blaney and Brian Vickers. Edwards finished fifth to drop 195 points behind Busch. Busch led 137 laps at the 1.5-mile oval, and celebrated his first Nationwide win in nearly three months by doing a couple of burnouts after grabbing the checkered flag.
