NASCAR Xfinity Series® rookie Connor Zilisch captured a series-best fourth victory of the 2025 season with a dominating performance in the rain-shortened BetRivers 200 at Dover. The JR Motorsports driver started third, but was in the hunt throughout. Zilisch took the lead for the final time following the Stage 2 restart and continued to show the way until rain forced the event to end at lap 134 of the scheduled 200.
