Ross Chastain, driving the No. 9 car for JR Motorsports, won the Charbroil 300 NASCAR O'Reilly Series race at Charlotte Motor Speedway on Saturday, May 26, 2026. The race was delayed by weather and only completed two stages before being called official, with NASCAR controversially choosing to run the final 10 laps of Stage 2 under caution due to poor track conditions. The victory marked Chastain's first win of the 2026 O'Reilly Series season.
