Series rookie Karam’s spin at Turn 7, which caused a race-defining full-course yellow, is under review by IndyCar.

It occurred soon after his Ganassi teammate Scott Dixon – who’s early lead had been eradicated by a badly-timed full-course yellow – had made his final pitstop.

The yellow also allowed Montoya’s title rival Graham Rahal, who was on pitroad as it happened, to make a huge inroad into his points lead.

“When everyone else pitted they had to save fuel from that point,” explained Montoya of the impact the yellow had on strategy. “It was hard for them to make it without a caution.

“And, you know, it’s kind of weird that all the Ganassi cars pitted and Sage spins. So it is what it is.

“I don’t know if it was on purpose or not, but I hear the spin was really dodgy.”

When asked if he thought there was some foul play there, Montoya replied: “Karma is a bitch, so we’ll see.”

When asked for his opinion, Dixon quipped: “IndyCar’s favourite is post-race reviews – we’ll find out on Wednesday I guess!”
