Andretti Autosport remained perfect on the year Sunday when defending IndyCar Series champion Ryan Hunter-Reay snapped Penske Racing's winning streak at Barber Motorsports Park. Hunter-Reay proved to be a credible threat for the victory when he beat both Will Power and Helio Castroneves for the pole. The Penske drivers had swept every pole and all three races in IndyCar's previous visits to the Alabama road course. Hunter-Reay then ran a steady race, and held strong in one intense battle for position with both Penske drivers, to claim his first win of the season. Then he had to hold off Scott Dixon, who finished second for the fourth consecutive year. "I was dragging my tail off trying to hold off Dixon," Hunter-Reay said. Castroneves was third to take over the IndyCar points lead, and Charlie Kimball, Dixon's teammate at Chip Ganassi Racing, was a career-best fourth. Power was fifth. AJ Allmendinger ran seventh for most of his IndyCar debut but finished 19th after stalling his car during his final pit stop. But he was praised repeatedly by team owner Roger Penske, even after the mistake in the pits. "Finish this and just learn, learn, learn. You are doing fine," Penske radioed Allmendinger.
