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.
