Power’s Andretti Global teammate Kyle Kirkwood was fourth while four-time champion Alex Palou completed the top five for Chip Ganassi Racing.

Malukas said he was happy to end up on top during a day that was spent getting up to speed with his team team

“I think it’s hard for test days, because you know, you’re running through your own plans – but I mean, of course, it feels good,” said Malukas.

“We know that we have pace. The car is good, and we’ve kicked off our oval set with the team on a strong suit.

“So I feel confident, but is it what we were aiming for today? No, we just ran through our test plan, and we managed to get a time up on the board.

“Does it feel good? Yeah, I would say it feels good.

“I’m feeling great. This is the best I’ve felt in a very long time. The chemistry I have with the guys, the team, I’m just so happy,” he added.

“I get to race this beautiful car. It’s fantastic. It’s a dream for me. So every time I come in and out of the pits, I’m smiling. I got a big smile on my face, and I think on top of that, it adds to the performance.

“You see that with all the other guys. You know, everybody is on it. They have their own missions to make sure that, as a team, we can get good results. Just being in that environment, it’s perfect.”

New Zealand’s interests were led by Marcus Armstrong, who was sixth for Meyer Shank Racing.
