Alex Palou conquered his third win in four races in the NYY IndyCar Series, the Chip Ganassi Racing charger prevailing on Sunday in the picturesque Wisconsin countryside at Road America.
The Spaniard edged Penske's Josef Newgarden by 4.5 seconds at the checkered flag while Arrow McLaren's Pato O'Ward was third.
In a race that enjoted four different leaders, Colton Herta led 33 of the event's 55 laps, but a final stint in fuel-saving mode undermined the Andretti Autosport driver's efforts.
"It’s been an amazing weekend," Palou said. "I’m super happy. They gave me the pit stop that gave us the win.
"It was an amazing day for the No. 10 American Legion Ganassi car, and we’re going to keep it going."
Palou's seventh career win in IndyCar expanded his lead in the championship to 74 points – more than one race worth of points – over teammate Marcus Ericsson.
