This Sunday at Phoenix Raceway, William Byron will compete in the NASCAR Cup Series Championship 4, striving to secure victory lane in his ongoing William Byron Phoenix championship chase. As the season culminates under the winner-take-all playoff format, every team in the garage, including Byron’s, is aiming for the top spot.
Byron and Larson Prepare for Phoenix Title Push
Both Kyle Larson and William Byron enter Phoenix with strong records at the 1-mile, dogleg oval. Larson, who captured a previous championship in 2021 at this very track, now seeks a second title. William Byron remains in pursuit of his first, with Sunday’s race marking a crucial opportunity to reach that goal. Their impressive histories at Phoenix fuel optimism; Larson holds the second-best average finish among active drivers at the Raceway with a 10.7 mark, closely followed by Byron at 10.8.
Performance History of Championship Hopefuls
Larson’s consistency at Phoenix Raceway stands out—he’s claimed 10 top-five finishes across 22 starts, the highest for any driver who has raced there less than 36 times. Meanwhile, Byron’s record includes nine top-10 finishes, tying this venue for the most top-10s he’s earned at any track during his career. These stats underscore why both drivers are considered formidable contenders in this year’s championship showdown.
Other Notables at Phoenix Raceway
Chase Elliott, another member of the Championship 4, already found Phoenix success in 2020 when a win secured him the championship. Elliott enters Sunday’s race riding consecutive top-10 results at the Arizona circuit. Alex Bowman, another native of Tucson, managed a seventh-place finish earlier this spring at his home track, further illustrating the competitive field at play.
What’s at Stake in the Final Race
Each contender has demonstrated strength at Phoenix Raceway, raising anticipation for a tightly contested championship battle. William Byron’s Phoenix championship chase will draw focus, especially as he aims for his first series title. Fans and teams alike will be watching closely to see which driver emerges victorious and captures the ultimate reward in the desert finale.
