Jamie Chadwick completely controlled the Indy NXT weekend at Road America to pick up her first pole position and first race win in the series.
The celebrations from the cockpit and her Andretti Global team showed how much this milestone meant for everyone involved after Jamie's steady progress since her debut last year.
Our 26-year-old development driver has already enjoyed a superb sophomore season in IndyCar's second tier,
taking to the podium one month ago at Indianapolis, but this weekend eclipsed even that momentous moment.

How it unfolded
A last-gasp lap in Qualifying Group 2 saw
a historic pole position secured in the dying seconds by just over two-hundredths of a second.
In the race, Jamie had teammate and British compatriot Louis Foster for company on her outside through the sweeping Turn 1 right-hander.
Stern inside-line defending meant Foster compromised his attack and ran wide, letting Jamie take the long run down to the heavy Turn 5 braking zone without a car trying to slipstream past.
Even though the lead never changed hands, this wasn't a race without challenge, with crashes further down the order wiping out any progress at each restart.
Nonetheless, the #28 Andretti controlled the field throughout the 20-lap race as the fight for P2 raged behind her.
Jamie kept a watchful eye on her mirrors while maintaining the gap until the chequered flag waved to cross the finish line and become an Indy NXT winner.

"I'm just so happy!"
Speaking immediately after stepping out of the cockpit and hugging her team, Jamie told the broadcast: "I'm a bit emotional. We've had an unbelievable car this year and haven't been able to do anything with it.
"I'm just so happy. With the red flag at the end, I was like, 'Oh, come on!'. I really wanted to win today.
"I'm just so thankful for the Andretti guys, honestly. Last year was a tough year, but they've helped me so much, so this is for them."
Mechanical gremlins mean 2024's results mask Jamie's true pace, but this race win more than made up for any earlier disappointments.
It was a flawless performance from lights to flag: soaking up pressure from behind in the opening laps and maintaining the lead despite not having a tow to help tackle the Wisconsin circuit's long straights.
Some drivers take their first series win thanks to their rivals making mistakes or wet weather.
Not so for Jamie, who instead used her speed to take pole position and racecraft to secure her first Indy NXT win as she continues going from strength to strength in America.
