Will Power says he’ll be giving nothing away after teammate Helio Castroneves entered the IndyCar championship battle with victory in Monday morning’s race in Edmonton.

Castroneves moved above Power into second in the championship standings with the victory, with Ryan Hunter-Reay still leading the Team Penske duo by 23 points despite a seventh place finish from the American.

Power, who had to start a lowly 17th after copping a 10-spot grid penalty for an engine change over the weekend, battled his way to third and is now three points behind Castroneves with four races left in the season.

And the Queenslander said it was game on as far as he’s concerned if it comes down to a championship battle between the two teammates in the closing rounds.

“I would expect that to be the case going into the last race,” said Power, who has finished as championship runner-up the past two years.

“What do you do? You just race him hard. I’m sure Penske has been in that position before, probably not for a long time, though.

“It’s basically competition on the track. There are no team orders in this team.

“I am sure that will be the case. I suspect there will be three or four drivers able to win in the last race.”

Castroneves, a three-time Indy500 winner, has also twice finished runner-up in the championship but appears confident he can emerge victorious in a battle with Power.

“Maybe with Will, (it) might be his first time, but I’ve been in this position,” the Brazilian said.

“I don’t see a problem at all. I actually want it, because that means I know what he’s got.

“Sometimes I know what I need to do to beat your enemy, let’s put it this way.”

Hunter-Reay, who was also hit with a grid penalty, was left fuming after claiming Power should’ve been penalised for cutting him off as the Queenslander exited pit lane early in the race.

“You’ve got to be kidding me! That is absolutely … ridiculous,” he yelled over the radio during the race when it was announced there would be no review by race control.

Power would go on to claim his fourth podium finish in as many years in Edmonton with what was his best finish since his win at Brazil in April.

“Good day all around,” Power said.

“If I thought that the race would go fully green starting 17th, I would have taken third any day.”

The next stop in the IndyCar schedule is the Honda 200 at Mid-Ohio on August 5.
