Power had reason not to be happy with his Penske team mate, who not for the first time this season had caused a highly unhelpful caution. Power and Dixon were among those who were obliged to pit at this point, while Dario Franchitti stayed out and assumed the race lead for the first time that afternoon.
As the race resumed on lap 37 with a lot of jostling and minor collisions but no major crashes: Franchitti fended off an assertive Oriol Servia followed by Justin Wilson, Ryan Hunter-Reay and local boy James Hinchcliffe; Power led those who had just stopped, but was now mired down in 11th place just ahead of Dixon and Conway, with the likes of Briscoe, Vitor Meira, Paul Tracy, Marco Andretti and JR Hildebrand in the way ahead.
The first green lap saw Dixon make contact with Hildebrand as he forced his way past, the rookie just able to keep it off the tyre wall in turn 3; a lap later and Canadians Paul Tracy and James Hinchcliffe found themselves going into turn 5 side-by-side. Tracy is not known as a driver who backs off from any fight, and young rookie Hinchliffe is apparently made of similar stuff so neither driver would give up, the cars banging wheels and Tracy coming out of it the worse with a spin that he was just able to save although damage to the front wing from the initial contact would send him into pit lane but without the need for yellow flags.
Instead the next caution was for James Jakes who had spun and stalled in turn 9. That allowed Graham Rahal to head for the pits for new tyres after apparently sustaining a right rear puncture on the sharp edge of Ryan Hunter-Reay's front wing; surprisingly Hunter-Reay opted not to pit at the same time despite clear damage to that front wing, preferring instead to hold on to the track position that he had gained from his early pit stop strategy.
And initially it seemed to be the right move, with Hunter-Reay able to follow Justin Wilson through when the Englishman made a lovely move on Oriol Servia for second place, forcing Servia off the racing line so that he then lost pace on the marbles which were seriously building up by this stage. But a few laps later and the wing's condition had worsened, Hunter-Reay had fallen down to seventh place and finally he conceded defeat and pitted on lap 47. It looked as though the Andretti team had made a horrible mistake with the gambit.
Or - maybe not. The very next lap saw a major multiple-car accident in the increasingly notorious turn 3. It was sparked by Paul Tracy - possibly still with some damage after his earlier contact with Hinchcliffe - locking up and running into Vitor Meira on the straight leading down into the corner; Sebastian Bourdais was immediately behind them on the road and had no where to go but into the side of Tracy as he spun, while Charlie Kimball tired to avoid the accident and ran into the barrier on the other side, leaving only a car's-width gap in the middle of the track for the rest of the cars to make their way through. Fortunately all cars were able to get back underway, although Tracy needed a lengthy visit to the pits for repairs.
With 36 laps to go till the end, it was a no-brainer that everyone now had to come in for their final pit stops - which potentially fell beautifully for those who had just been into the pits such as Graham Rahal, who assumed the lead, and Hunter-Reay who now found himself in 5th place after that suddenly-fortuitous fluke stop for a wing change at just the right moment. Dario Franchitti resumed in sixth place ahead of Justin Wilson, Will Power and Scott Dixon, Power having had a flying pit stop thanks to having less fuel to take on board after his more recent stop than Franchitti and Wilson.
Franchitti had a poor restart and was passed by Justin Wilson, and that broke Dario's momentum just enough for Will to pounce and get past him as well. The two were still running together when Mike Conway ran into the back of Ryan Briscoe and shunted them both off into a run-off area.
"I have to apologize to Ryan for ruining his race; completely a brain fade on my part," confessed Conway. "Going into the turn, I tried to take my time and get to the inside, but it seemed to choke up a bit. There was nowhere to go. It was kind of a slow incident but it broke the left side suspension. End of a tough day for the team."
Like the earlier Sato/Patrick accident in the same spot, this was dealt with under local waved yellows; but the next caution was out on lap 57 anyway. And the reason for it was a clash between the two main title contenders, Dario Franchitti and Will Power.
