Race 1’s final lap culminated in Wagner finishing third and missing the victory by .013 seconds after a three-way drag race to the finish line. In Race 2, after learning from the finish of Race 1, Wagner made a last corner pass to bring the Spark Performance #5 entry the second win on the season.

The top 3 of Michael Carter, Selin Rollan, and Wagner battled through the final lap in a fight that saw all three cross the finish line within .013 seconds. Rollan ultimately came out on top in Race 1.
Wagner’s second fastest lap in qualifying was good enough for a third place grid spot for Race 2. He immediately took the lead on the opening run to turn 2, and again lead the majority of the laps. A late race FCY set the field up for a final sprint to the finish. Wagner maintained his lead into the final lap, until Carter drafted past on the Ulmann Straight before the final corner. However, Wagner challenged into turn 17 and emerged with a .964 second gap to Carter, crossing the line with a comfortable margin to take his second win in 2021 and maintain the championship points lead.
