Marco Andretti led a powerful Andretti Autosport rout Friday as all four drivers landed in the top five of qualifying at the Milwaukee Mile.
Andretti won the pole with a two-lap average speed of 170.515 mph around the mile oval. James Hinchcliffe was second at 170.418 for a 1-2 finish for the Andretti cars.
Will Power broke up an Andretti sweep by qualifying third at 170.212.
But Power was followed by defending race winner Ryan Hunter-Reay and E.J. Viso as the Andretti drivers proved they are the ones to beat Saturday in the 250-mile IndyCar race.
Sebastian Saavedra was sixth and Tony Kanaan was seventh as Chevrolet drivers swept the top seven spots.
Josef Newgarden was the highest qualifying Honda at eighth.
Andretti Autosport has won four of the last eight races at Milwaukee.
