Points leader Ryan Briscoe went wheel to wheel with fellow championship contender Scott Dixon on the last lap and came out on top, winning Saturday night's IndyCar series race at Chicagoland Speedway in Joliet, Ill., by only 0.0077 of a second.
Dixon finished second by a nose, followed by Mario Moraes and another championship contender, Dario Franchitti -- keeping the series title fight tight going into the last two races of the season. Graham Rahal finished fifth.
Briscoe's Penske Racing teammate, Helio Castroneves, appeared to break a suspension part and hit the wall with 16 laps to go.
It was the fourth-closest finish in series history. Three of the series' four closest finishes have come at Chicagoland.
With his third victory of the season, Briscoe leads Franchitti by 25 points and Dixon by 33 going into the final two races. Castroneves, who came into Saturday night's race fourth in the points, was eliminated from title contention after his crash.
Graham Rahal rounded out the top five. Danica Patrick finished 12th.
The race was fast and caution-free until nearly the halfway point, when Andretti Green Racing driver Hideki Mutoh lost control of his car and hit the wall hard on Lap 92. Mutoh was able to climb out of the car on his own.
