@tobychristiecom: William Byron, FINALLY, claimed his first win of the 2026 #NASCAR Cup Series season in a dominant performance in Sunday's Xfinity 500 at Martinsville Speedway. Kyle Larson, the championship leader, finished ninth, and was unable to secure the championship a week early. However, Larson will have a major point advantage over Christopher Bell and Denny Hamlin heading into the season finale.
