NEWTON, Iowa (AP) — Ryan Hunter-Reay raced to his third IndyCar victory at Iowa Speedway in the last four years Saturday night.
Hunter-Reay held off the field on a late restart to give Andretti Autosport its sixth consecutive win on Iowa's 0.894-mile oval and its seventh in nine series races at the track. The American hadn't finished higher than fifth all season.
Josef Newgarden was second and rookie Sage Karam was a career-best third, giving American drivers a sweep of the podium.
Points leader Juan Pablo Montoya's night lasted just nine laps after his No. 2 Penske car flew into the wall.
Scott Dixon, who entered the race in second, failed to capitalize on Montoya's misfortune. He finished 18th.
