Shortly after the restart on lap 149, Patrick dropped back to seventh place (last car on the lead lap) in a fuel conservation strategy to have enough fuel to challenge the leader at the end of the race. With the race remaining green, during the final ten laps, most of the leaders, not having enough fuel to get to the end, ducked off the track for "splash-and-go" pit stops for fuel. Despite topping off his tank earlier, Ed Carpenter, getting poorer fuel economy than the rest of the lead-lap cars, was forced to pit for fuel. Castroneves inherited the lead with less than 5 laps to go, with Patrick charging in second place. Castroneves slowed his pace to conserve fuel, and Patrick took the lead with 2 laps to go. Patrick held on to win, and became the first female to win a race in the history of top-level American open wheel racing.
