NEWTON, Iowa – Ryan Hunter-Reay passed Scott Dixon with 12 laps to go and held on to win for the second straight week in a wild IndyCar Series race that ended under caution Saturday night.Hunter-Reay, the winner last week at the Milwaukee Mile, moved to second in the season standings with his seventh career IndyCar victory. The victory was Andretti Autosport's fourth in six races in Iowa. Teammate Marco Andretti was second, followed by Tony Kanaan and Dixon. Andretti won last year on the 0.875-mile (1.41-kilometer) oval. It was only fitting Hunter-Reay would win under caution, because 10 of the 25 cars failed to finish. What was also notable was that Hunter-Reay essentially used the same setup Andretti tested with at Iowa last week to beat his teammate. Hunter-Reay crossed under yellow as Katherine Legge spun out with two laps left. “We basically raced the way he tested it. Marco and I raced really hard out there. It's great to have a teammate like that. So happy to be in victory lane twice in a row,” Hunter-Reay said. It seemed as if Hunter-Reay was about the only driver to leave Iowa with a smile on his face. Pole sitter Dario Franchitti was knocked out after his engine blew before the green flag dropped. Points leader Will Power retired just 68 laps in after E.J. Viso hit him from behind and saw his series lead dwindle to three points. James Hinchcliffe caught the wall and didn't finish either. A race delayed for 45 minutes by storms and marked by a series of early incidents seemed to finally become clear with 71 laps to go. — AP
