Franchitti took a big stride toward defending his IZOD IndyCar Series title with the victory, during which he opted not to take on new tires amid a late-race round of pit stops under caution.
Current points leader Will Power had to pit unexpectedly for fuel with four laps left and ended in 16th place. He saw his lead over Franchitti trimmed to 23 points with three races to go.
Wheldon finished second, Andretti ended up in third, Ryan Hunter-Reay came in fourth and Tony Kanaan claimed the fifth spot.
