Byron Overcomes Pit Speeding Penalty to Win BetMGM 300

Byron's burnout after taking the checkered flag

(CONCORD, NC  - MAY 24, 2025 - RIS) After receiving a pit-road speeding penalty at the end of Stage 2, Hendrick Motorsports driver William Byron bounced back in NASCAR Overtime, passing JR Motorsports’ Justin Allgaier to win the Xfinity Series race Saturday at Charlotte Motor Speedway.

Once Byron got stuck in traffic, following the penalty, he struggled to make his way back toward the front of the field. But multiple late-race cautions allowed him to close the gap and capitalize in overtime for his fifth career Xfinity Series victory.

"I was somewhat confident," Byron SAID after the race.. "I felt like if we got some yellows, we'd be good but man, that didn't work out the way we thought it (would). Just had a lot of green flag running and couldn't really get back to the front. But man, feels awesome to win. This is my home track. It feels really good. Restart merchant there at the end. It's fun to be back in Victory Lane. I feel like I haven't won in a while."

Allgaier didn’t like the final laps of the race. He went against his crew chief's wishes and stayed out on older tires when most of the field chose to pit. A series of yellows helped him to remain out front, but those who pitted for fresh rubber continued to make up spots and creep closer. On the final restart, he had three fast drivers who had made four-tire stops directly behind him.

"Being the leader is a tough spot in that regard," said Allgaier, who led 101 of 205 laps. "I saw the #00 [Sheldon Creed] was staying out anyway and to be honest with you, I should have just come down pit road. All things aside, I thought there was going to be a lot of games played on pit road. And I felt like if things got settled out and they had to travel through all of that traffic, we were going to maybe net okay. And then all of those cautions, one after another -- it was great because we were able to hold those guys off but it really just hurt us because they were able to get a spot or two every restart.”

Bryon did get a break during a cycle of green flag pit stops with just over 50 laps to go, a caution flew for debris after Taylor Gray suffered a flat left-rear tire. Byron was trapped a lap down and had to take the wave-around.

In the final laps, restart saw the cars with four fresh tires finally arrive at the front of the field with Zilisch harassing Allgaier for the lead, even with a tire rub. But just as he was making the move, more cars piled up on the backstretch, with Brandon Jones tagging the wall before getting run over by Leland Honeyman Jr. Kyle Sieg got collected as the wreck unfolded. This pushed the race into overtime and Allgaier gave it everything he had. Byon pulled to the outside of Allgaier and the two made slight contact on approach to the white flag with Allgaier nearly spinning. Byron skipped away as Allgaier faded on the final lap, which ended under caution due to a heavy accident involving J. Burton and Brennan Poole.
