Their rookie teammate Dylan Ferrandis was also in a solid top-10 position, but ultimately crossed the line 12th after a late-race crash. Although Saturday’s track at the NRG Stadium was an all-new layout, it still presented some challenges. Stewart struggled a bit in practice but had a great Heat race, finishing third. He got a good start in Main Event behind Plessinger and then advanced to fourth five laps later. The Florida rider held the position for a few laps before being passed by a couple of riders. With a top-five finish in sight, Stewart kept pushing but ultimately had to settle for sixth.
