Tony Kanaan took advantage of teammate Dan Wheldon's misfortune to move into the lead, then ran away from the field yesterday to win the Argent Mortgage Indy Grand Prix in Sonoma, Calif.

Kanaan beat Buddy Rice by 1.182 seconds -- about eight car-lengths -- for his second IRL IndyCar win of the season, completing a sweep for Andretti Green Racing. Owner Michael Andretti's son, Marco, won the Menards Infiniti Pro Series earlier in the day.

It was Wheldon's broken fuel pump that allowed Kanaan to take the lead on the 53rd of 80 laps at Infineon Raceway.

"I have had bad days and he capitalized a lot on them," Kanaan said of Wheldon, the IndyCar points leader.

Kanaan averaged 91.040 mph around Infineon's 12-turn, 2.26-mile track in the first IRL race held on a road course.

* CHAMP CAR: Oriol Servia was handed his first circuit victory when series officials ordered rookie Timo Glock to let him pass on the final lap of the Montreal Molson Indy race.

Glock found himself in the lead late in the 79-lap race and tried desperately to hold onto the top spot, twice blocking Servia's Newman/Haas Racing Lola as the two nearly bumped.

Saturday's Nextel Cup

Matt Kenseth used his first victory in over a year to strengthen his frantic push to make NASCAR's playoffs, winning at Bristol Motor Speedway on Saturday in dominating fashion.

Kenseth started from the pole and led a whopping 415 of the 500 laps to win for the first time since March 7, 2004. His team had struggled for most of the past year, but a late-season surge has helped him close in on qualifying for the Chase of the Championship.
