Lap 110- Moreno closes to within 0.5s of de Ferran

Lap 108- de Ferran and Moreno 1.1s apart, Fittipaldi 11s back in third. Castroneves is fourth with Andretti, da Matta and Brack right behind him

Lap 107- Conflicting reports over Moreno's fuel situation, but he is still right with de Ferran.

Lap 106- Castroneves drops to at least fourth behind the battling de Ferran and Moreno, and third-placed Fittipaldi

Lap 105- Top three covered by 0.8s, Moreno working hard on de Ferran. Crew getting ready for Castroneves

Lap 104- Castroneves still leading but still struggling. De Ferran is being patient behind but Moreno is closing on him

Lap 103- Castroneves and de Ferran running in formation but Castroneves should need another pit stop. Moreno is 3s behind in third.

Lap 102- da Matta pits and drops to sixth behind Castroneves, de Ferran, Moreno, Fittipaldi and Andretti

Lap 98- Castroneves will probably have to stop again too. Speculation that he only received a full fuel load in his second stop because of an error by the crew. The original plan was for both Penskes to be short-filled so they could go flat-out and make a later splash and go. Race order: 1 Castroneves, 2 da Matta, 3 de Ferran, 4 Moreno, 5 Fittipaldi, 6 Andretti, 7 Brack, 8 Servia, 9 Franchitti, 10 Carpentier, 11 Tagliani, 12 Nakano, 13 Fernandez, 14 Marques, 15 Garcia Jr, 16 Herta

Lap 97- Only 0.4s separates Castroneves and da Matta, the latter almost certainly needs to pit again but the leader could have conserved enough fuel to make it to the flag. De Ferran now within sight of the leaders, he has already pitted

Lap 96- Andretti pits from third, leaving da Matta to work on Castroneves

Lap 95- da Matta and Andretti are all over Castroneves as Servia pits from sixth. de Ferran is only 4s off the lead and closing all the time as Castroneves' gearbox problems get worse

Lap 93- Top three drivers are covered by 1.5s but both da Matta and Andretti could be making stops soon. Tagliani pits from a charging sixth and appears to have a mechanical problem

Lap 92- Race order: 1 Castroneves, 2 da Matta, 3 Andretti, 4 de Ferran, 5 Moreno, 6 Tagliani, 7 Brack, 8 Servia, 9 Fittipaldi, 10 Nakano, 11 Franchitti, 12 Carpentier, 13 Fernandez, 14 Marques, 15 Garcia Jr, 16 Herta

Lap 90- de Ferran leaves after a 9s stop but is down to fourth, behind Castroneves, da Matta and Andretti

Lap 89- De Ferran leads by 22s and is about to hit traffic. He makes his final pit stop...

Lap 88- Yet more drama for Montoya, he pits and retires with another mechanical problem

Lap 87- Castroneves reports a problem with the gearbox on his Penske Reynard, he is struggling with third gear and losing time to de Ferran. da Matta is capitalising and putting Castroneves under huge pressure. Andretti is the first non-Brazilian and is right behind them

Race order: 1 de Ferran; 2 Castroneves; 3 da Matta; 4 Fittipaldi; 5 Andretti; 6 Moreno; 7 Montoya; 8 Tagliani; 9 Servia; 10 Brack; 11 Nakano; 12 Franchitti; 13 Carpentier; 14 Marques; 15 Fernandez; 16 Garcia Jr; 17 Herta. Tracy is now out with broken suspension. Fittipaldi will definitely have to stop again, de Ferran and Andretti may also be doing so judging by their lap times

Lap 76- Moreno pits, problem with fuel nose, no fuel is going into the car. Problem eventually solves itself. De Ferran leads and is pulling away, his stop was much quicker than Castroneves' and he is now lapping a second faster, suggesting that Penske is hoping that Castroneves can finish the race without another stop, while De Ferran goes flat-out right now but may have to make a splash-and-go stop near the end of the race.

Lap 75- Tracy pits and switches the engine off, possibly out of the race

Lap 73- Moreno leads but has yet to pit

Lap 73- Castroneves pits from the lead, longer stop than de Ferran

Lap 59- Castroneves' lead is being eroded because he is being held up by Garcia Jr, who he is trying to lap. The CART officials are likely to take action against the Brazilian

Lap 55- de Ferran back to within 1.6s of Castroneves. He still has Moreno and da Matta shadowing him but Montoya has dropped back slightly

Lap 44- de Ferran closes the gap to Castroneves from 5.5s to 3.6s, pulling away from Moreno and da Matta in the process. Herta lost time in his pit stops because the fuel vent would not open, meaning he had to come in again for a second stop, which again took too long because of this problem.

Lap 40- Moreno and da Matta make minor contact in the battle for third but continue unscathed with Montoya on their backs.
