Dario Franchitti, the championship leader took his first pole of the season after the Saturday qualifying was washed out due to rain, which meant that the grid was decided by Friday qualifying times. Franchitti led away at the start followed by Bryan Herta, although Paul Tracy soon passed Herta and took second. The Team Green duo of Franchitti and Tracy then pulled away from the field, building a lead of 12 seconds. After the first round of pitstops, Franchitti and Tracy stayed 1-2, but Juan Pablo Montoya was up to third after a quick stop. He was 15 seconds behind the Team Green cars, but he was unfazed by that and set about closing it down, and did so rapidly such that the top three cars were nose to tail before the second round of pitstops. Franchitti pitted, handing Tracy the lead, but that did not last for long as he was immediately passed by Montoya. Montoya and Tracy both made their second pitstops and both rejoined ahead of Franchitti, before a caution due to Luiz Garcia, Jr.'s spin bunched the field up. Tracy and Franchitti were quicker than anyone else on the track, but both were absolutely no match for Montoya, who set a stunning pace in the final stint once the track went green, and won by over 10 seconds. Tracy finished second and Franchitti third, which was enough for him to keep his championship lead, although it was down to 1 point.
