A first win in more than two years for Colton Herta, a massive crash for Pato O’Ward, and a Penske driver crashing into his team-mate provided a thrilling Toronto IndyCar race that shook up the championship order massively with five races left to go in the season.

Behind Herta, Kyle Kirkwood bagged a first podium of the season to make it an Andretti 1-2 at a track where team-owner Michael Andretti has more wins than anyone.

Herta's victory ended a winless streak stretching back to his outstanding win in the wet on the Indianapolis road course in May 2022.

O’Ward’s crash and Scott McLaughlin being shunted off by Will Power means a huge boost in the championship for Alex Palou, who drove from 18th to fourth in the order.

O'Ward's enormous shunt

An enormous and terrifying crash ended what had been a brilliant comeback drive from O’Ward.

He spun on his own entering Turn 1 on lap 73 of 85 after a restart while running sixth, ahead of Palou at the time, and was facing the wrong way on the corner exit as a host of cars crashed into him.
