Australian pole-sitter Will Power crashed out before American teammate Josef Newgarden claimed his fourth IndyCar series victory of the season in Madison, Illinois, extending his championship lead.

The 26-year-old Newgarden won by 0.6850 seconds from New Zealand’s Scott Dixon (Chip Gnassi Racing) with fellow Team Penske driver Simon Pagenaud third.

The first 17 laps of Saturday night’s race were run under yellow after the caution came out before the cars could make an official lap when Tony Kanaan spun out at the exit of Turn 2.

Then when the green flag finally flew, Power immediately dropped to third entering Turn 1 as Newgarden took the lead.

But, before Power could make it through Turn 2, he spun, hit the outside wall and Ed Carpenter flew in the air and over the top of Power’s machine.

Indianapolis 500 winner Takuma Sato also spun in the melee. All three were unable to continue.

Newgarden increased his series points lead over Dixon with two races remaining in the 17-race schedule.

He led 61 of the 248 laps on the 1.25-mile oval en route to his seventh career victory and Penske’s fourth at Gateway and 196th overall.
