on lap 65, and on the ensuing round of yellow-flag pit stops, both Scott Dixon and Raphael Matos lost wheels while pulling out and had to return to their pits. Kanaan improved eight spots, from 12th to 4th, on the same round of pit stops. Matos's race did not last much longer, as he spun into the wall on lap 73. Second half Vítor Meira hit the turn two wall in lap 106, bringing out the race's next caution. Ed Carpenter, who had been running well, had to come into the pits before they were officially open to avoid running out of fuel, but the rules then required him to come in again once the pits were open, costing him several spots. While most drivers came into the pits on the yellow, Tomas Scheckter stayed out, briefly taking the lead, but Franchitti quickly took it back after the race returned to green-flag status. A long stretch of green-flag racing followed. Kanaan passed Hélio Castroneves and Scheckter to take the second spot, but Franchitti pulled away and had a lead of 9.7 seconds over Kanaan by lap 142. A series of green-flag pits on laps 143–147 resulted in Marco Andretti and Ryan Briscoe briefly taking the lead, in turn, before they had to pit and Franchitti re-emerged as the leader, with Andretti Autosport teammates Andretti and Kanaan in second and third, respectively. On the same round of pits, Castroneves stalled his car leaving the pits, dropping him from third to sixteenth. Continuing Penske Racing's problems, Briscoe crashed into the turn four wall on lap 148. Most drivers stayed out during this caution, but Castroneves pitted, hoping that there would be enough additional laps under caution to extend his fuel mileage and allow him to finish the race without pitting again. Kanaan passed Andretti under the following green flag to retake the second position. Finish A spin by rookie Sebastián Saavedra on lap 161 brought out another caution, and most drivers came into the pits, but Mike Conway, Justin Wilson, Castroneves, and Graham Rahal all stayed out, taking the top four spots, respectively. In the end, none of the four had enough fuel to complete the race and all had to pit before the end of the race under a green flag, giving Franchitti the lead again on lap 192, with Kanaan again in second. Kanaan's hopes for a "worst-to-first" race came
