New Zealand's Scott Dixon has qualified 4th for Monday's Grand Prix of Alabama behind Brazil's Helio Castroneves who captured his second straight Indy Car series pole.
The reigning Indy Car champion Will Power of Australia was second-quickest followed by Simon Pagenaud of France.
Castroneves clocked 1min 07.1925sec on the 3.7km, 17-turn course to lead a Team Penske sweep of the top three qualifying spots.
His time stood up as the decisive fast six final stage of qualifying was called off with less than two minutes remaining because of lightning.
Castroneves's pole position, on a track where he won in 2010, comes a week after he set a course record in claiming pole at Long Beach where he eventually finished runner-up Dixon.
Castroneves trails leader Juan Pablo Montoya of Colombia by three points in the series standings.
Dixon, a three time Indy series champion, is fourth in drivers championship driving for Target Chip Ganassi Racing Chevy.
