MADISON, Ill. -- Takuma Sato held off Ed Carpenter to win the IndyCar race Saturday night at World Wide Technology Raceway.
It was Sato's second victory of the season. Tony Kanaan was third, followed by Santino Ferrucci and Simon Pagenaud.
Pole sitter and series points leader Josef Newgarden spun coming out of Turn 4 of the final lap and finished seventh.
Sato won by 0.399 seconds. The victory comes on the heels of his highly scrutinized move on the first lap at Pocono last week that helped trigger a major accident.
Sato denied Team Penske a sweep of the ovals this season and gave Rahal Letterman Lanigan Racing a sorely needed victory.
Defending race champion Will Power finished last after he crashed in Turn 4 of lap 54.
IndyCar's Astor Cup, awarded to the series champion every year, was on display on pit road before the race along with the NHL's Stanley Cup. The St. Louis Blues won the Stanley Cup for the first time in June.
Sato's team and Spencer Pigot's team will be paying fines after each driver ran over equipment during a pit stop.
IndyCar's next stop will be in Oregon, at the road course at Portland International Raceway on Sept. 1 for the Grand Prix of Portland. Sato is the defending champion.
