Ryan Hunter-Reay watched the finish from the pit lane knowing that his championship lead was gone and Power was back in control: but Dixon's late move to the front meant that Power's margin over Hunter-Reay ended up being only 5pts.
"It's disappointing to start the day with a 23-point lead and leave in second place, but we'll get over this quick," said Hunter-Reay. "There's a lot of racing still to go, and the only thing we can do is dig deep and move on.
"I think it's going to be a good championship fight, but you can't have any more days like this," he admitted. "I'm confident we're going to be right in it until the finish - it's certainly do-able for us to win it all."
Helio Castroneves finished the race in 16th place but retains third in the championship battle just 26pts off Power despite the weekend's setbacks; and Scott Dixon's race win puts him into fourth place just 2pts back from Helio. With three races still to run before the end of the 2012 season, the title really could go to any of the four.
