Colton Herta wins chaotic, rain-soaked IndyCar GMR GP on Indianapolis road course

Colton Herta won a wild GMR Grand Prix, which descended into chaos Saturday as intermittent rain turned many NTT IndyCar Series drivers’ fortunes upside down on the Indianapolis Motor Speedway road course.

It also was the first victory of the season for Honda after four consecutive victories by Chevrolet to start 2022.

Simon Pagenaud finished second, followed by Will Power, Marcus Ericsson and Conor Daly.

“I couldn’t see; I couldn’t drive at the end,” Pagenaud told NBC Sports’ Kevin Lee. “The car felt really good in the wet, but I just
