Simona de Silvestro set the fastest time of the weekend with a 1:07.4073 this morning, ahead of the Hondas of Simon Pagenaud and Scott Dixon. The past two champions Ryan Hunter-Reay and Dario Franchitti were fourth and fifth respectively.
JR Hildebrand was a surprising sixth but even more surprising than him was AJ Allmendinger in seventh, the fastest Penske entrant. Tristan Vautier, Justin Wilson and Will Power rounded out the top ten as Honda appears to have closed the gap from St. Petersburg. Both manufactures had five representatives in the top ten.
James Hinchcliffe was 11th ahead of Castroneves, Tagliani, Viso, Bourdias, Jakes, Kanaan, Rahal, Kimabll and Serviá.
The bottom six were Newgarden, Saavedra, Andretti, Sato, Carpenter and Beatriz.
The biggest news from the morning was the announcement AJ Allmendinger will run the Long Beach Grand Prix in a fortnight.
Should the results from third practice carry over to qualifying the following drivers would advance to the Fast 12.
Group One: Pagenaud, Dixon, Hunter-Reay, Franchitti, Allmendinger and Tagliani.
Group Two: de Silvestro, Hildebrand, Vautier, Wilson, Power and Hinchcliffe.
Qualifying takes place at 11:25 AM ET.
