Race 5 of 33: Service King 300 at Auto Club Speedway

Track Specs: 2-mile D-shaped oval / 150 laps

Weather: Mostly Cloudy; 65 degrees

Race Winner: Kyle Larson

Byron’s Finish: 5th


Capturing his second top-five finish of the season, William Byron and the No. 9 Axalta/Dura Coat Chevrolet brought home a fifth-place finish in the Service King 300 and was the highest finishing Xfinity Series regular at the end of the 150-lap event. The No. 9 team remains second in the NXS championship standings, 17 points behind teammate Elliott Sadler.


The Axalta/Dura Coat Chevrolet qualified sixth for the 300-mile race and the team knew they had a car that would be fast during the race. Early into the first green-flag run of the day, Byron brushed the wall but remained inside the top 10. After the contact, the 19-year-old came over the radio and relayed to the team that his Chevrolet fired off too tight. When the first caution flag of the day was shown on lap 30, the team elected to pit for four tires, fuel and a track-bar adjustment to help with a tight-handling car.


At the conclusion of Stage One, Byron was scored in the fifth position and reported to the team that his Chevrolet fired off much better after those adjustments. The Charlotte native stayed inside the top 10 for the majority of Stage Two and reported on lap 62 that his machine needed help on the initial turn and down the center. The No. 9 team came down pit road for four tires, fuel and additional adjustments.


After a quick pit stop, Byron was set to restart from the fourth position on lap 78. Five laps later the caution flag was shown once again. The Axalta/Dura Coat machine needed help in the center to the landing, but the team elected to stay out to maintain their position on-track. When the green flag waved on lap 89, Byron and the No. 20 of Erik Jones battled for the third position for the majority of the next green-flag run.


Under caution on lap 97, the No. 9 car came to the attention of the pit crew for four tires, fuel and adjustments. With another fast stop by the pit crew, Byron restarted from the second position. The sixth caution of the day was shown on lap 108 and Byron reported that his car needed to be tightened back up. The team came to pit road for four tires, fuel and another track-bar adjustment. There were a number of cars who did not elect to hit pit road, forcing the No. 9 team to restart from the 16th position on lap 115. Byron remained quiet on the radio during the next green-flag run, while he battled his way through traffic.


On lap 146, Byron was scored in the sixth position and would advance one position to finish the race fifth. Kyle Larson brought home the win and was followed by Joey Logano, Kyle Busch, Jones and Byron rounding out the top-five.


William Byron, driver No. 9 Axalta/Dura Coat Chevrolet team

“It has been good to get these top-five finishes lately. We were able to make some really good adjustments throughout the race. I felt like we kind of struggled at the start of the race in traffic and trying to get the car to handle right. After some good adjustments, we got the car where we needed it to be and were able to get some track position. The guys on pit road did a great job all day and we were able to run up front, which is always fun. We will use this momentum throughout the week off and come back strong in Texas.”
