Kiwi Scott Dixon avoided drama in an incident-filled Indycars race on the streets of Toronto to claim his 44th career win and give his championship charge a massive boost.
Dixon inherited the lead a third of the way through the race and powered to his third win of the season while most of his championship rivals ran into problems, including second-placed Josef Newgarden.
The Kiwi nearly doubled his championship lead, which is now worth 62 points ahead of Newgarden. He led home Simon Pagenaud and Robert Wickens.
"I am worn out – that was definitely a physical race," Dixon said.
"With those stop-goes it was easy to pick up debris on those tyres and I think that is what happened to Josef. He tried to go a little bit faster going into the last corner, got into the grey and that was pretty much it.
