New Zealand driver Scott Dixon has backed up last week's IndyCar victory in Pennysylvania by winning the first race of the doubleheader in Toronto.
Dixon, who started fifth in the 85-lap race overtook race leader Sebastien Bourdais on Lap 78 and held off the four-time CART champion.
Dixon's Target Chip Ganassi Racing Honda team-mate Dario Franchitti finished third.
It was Dixon's 31st victory, tying Bourdais, Franchitti and Paul Tracy for seventh on the all-time Indy car list, and puts him third in the overall series standings.
Dixon, who won his first race of the season at the Pocono Raceway 2.5-mile tri-oval last weekend, will start race No. 2 tonight from the pole.
