William Byron emerged victorious in a thrilling, crash-filled overtime finish at the NASCAR Xfinity Series BetMGM 300 on Saturday at Charlotte Motor Speedway. This marked Byron’s fifth career Xfinity win and his first on his home track. After overcoming a pit-road speeding penalty and fighting through multiple cautions, the Hendrick Motorsports driver secured a dramatic victory to start the Coca-Cola 600 weekend on a high note.
The race featured intense competition, strategic gambles, and several late-race cautions that reshuffled the field. Connor Zilisch, Nick Sanchez, Justin Allgaier, and Dean Thompson rounded out the top five, though initial fifth-place finisher Sammy Smith was disqualified after failing post-race inspection due to improper weight.
A Rocky Start: Penalty Sends Byron to the Back
The race was a test of resilience for William Byron. Early in the race, a pit-road speeding penalty during the Stage 2 break put Byron to the back of the field for the restart on Lap 99. For many, this would have been a tough blow, but Byron and his Hendrick Motorsports crew kept their focus.
Byron fought through the field, relying on caution periods and strategic restarts to regain lost ground. Despite long stretches of green-flag racing that made it difficult to gain positions, Byron remained confident that fresh tires and timely yellows would give him a shot at the win.
Justin Allgaier’s Risky Call and Its Fallout
Justin Allgaier, the reigning NASCAR Xfinity Series champion, led the race for 103 laps, the most of any driver that day. He controlled much of the middle portion of the race, including leading under caution on Lap 180.
However, Allgaier made a pivotal strategic decision that ultimately cost him the victory. Choosing to stay out on older tires during the caution rather than pit for fresh rubber, Allgaier hoped to hold his track position and fend off challengers. That gamble appeared sound initially but backfired in the closing laps.
Byron, who pitted for fresh tires, had the grip advantage and was able to reel in Allgaier on restarts. The fresher tires gave Byron the edge in the overtime shootout, where he passed Allgaier on the very first lap of overtime and held on for the win.
Late-Race Drama: Multiple Cautions Shake Up the Field
The BetMGM 300 was marked by 11 caution flags, with several incidents in the closing laps that significantly impacted the race outcome. A violent wreck involving Jeb Burton and Brennan Poole triggered the 11th caution, freezing the field and setting up the dramatic overtime finish.
Before that, a multi car wreck on Lap 184 shuffled the running order, forcing Byron to restart ninth. Additional cautions slowed the field, giving Byron multiple chances to improve his track position. Notable wrecks involving drivers like Katherine Legge and JJ Yeley, and later Brandon Jones’ crash collecting multiple cars, kept the intensity high until the final laps.
Rookie Standouts Shine and Full Results
The race also highlighted several Sunoco Rookie of the Year contenders, who put in impressive performances. Connor Zilisch, Nick Sanchez, Dean Thompson, and Christian Eckes all finished in the top 10, demonstrating the depth of young talent in the Xfinity Series.

Post-Race Inspection Drama: Smith’s Disqualification
While Sammy Smith initially finished fifth, the post-race inspection brought a major shakeup. Smith’s No. 8 car was found to be underweight, leading to his disqualification and relegation to last place. This disqualification elevated Dean Thompson to fifth in the official results.
Other cars, including those driven by Nick Sanchez, Dean Thompson, and Ryan Sieg, were sent back to the R&D Center in Concord for further inspection, underscoring NASCAR’s commitment to strict technical standards.
