William Byron Dominates at Martinsville While Kyle Larson is One Step Closer to Back-to-Back Championships

William Byron dominated Sunday's NASCAR Cup Series Xfinity 500 at Martinsville Speedway, capturing his first victory of the season and his 17th career win. The Hendrick Motorsports driver led 362 of the 500 laps and swept both stages, ultimately finishing 2.049 seconds ahead of teammate Chase Elliott. Ty Gibbs finished third, followed by Josh Berry and Shane Van Gisbergen.

Meanwhile, Kyle Larson placed ninth, moving into prime position to secure back-to-back championships heading into the season finale at Homestead-Miami Speedway. Larson holds a 67-point lead over Christopher Bell and a 70-point lead over Denny Hamlin. Larson now needs only a 28th-place finish or nine points in the final race to claim his third career Cup Series title.
