The Swede led opening lap, which started under caution due to a race control issue, but quickly lost out to fellow front row starter Will Power once the green flag came out on lap two of 85.
It proved to mark the beginning of a downward slide, as Rosenqvist quickly fell to fourth by lap five. He had dropped two more places across the next three laps and never managed to recover the lost track position on his way to finishing ninth.
“The opening segment is where we essentially lost the race,” Rosenqvist said.
“We had some issues with the brakes: they were running really hot, so I was really off on my bias and had to chase it.
“We really lacked braking performance, which meant I kept getting passed in Turn 1, inside and outside. Without braking confidence, you can't protect, and you can't go forward.
“But the team did well despite that, we kept our heads cool - even though it sucked to go plummeting down the field.”
With two front row starts and two top 10 results from the opening two points-paying races of 2024, having finished seventh in St. Petersburg before the disqualification of Team Penske drivers Josef Newgarden and Scott McLaughlin for push-to-pass violations elevated him two positions, Rosenqvist sits sixth in the standings just 24 points behind leader Scott Dixon.
