The race was won by Australian racer Ryan Briscoe racing for Team Penske. Briscoe finished 0.4 seconds ahead of Australian team mate Will Power with British driver Dario Franchitti finishing third for Chip Ganassi Racing. It was Briscoe's first win since the 2010 Firestone 550. Brazilian driver and Formula One veteran Rubens Barrichello finished fourth in his best result since joining IndyCar. Power's second place, coupled with Ryan Hunter-Reay finishing 18th expanded Power's lead in the championship. Power led Hunter-Reay by 36 points.
The event marked a notable change in the course layout. The cars used the inner loop at the back hairpin instead of the outer loop in order to open a passing zone. The exit of the bus stop was widened to allow for more room. Another passing zone was established by using a part of the hairpin instead of cutting it off altogether.Classification
