Reddick ended up second-fastest (93.763 mph) and Austin Cindric was third (93.459 mph).
“I don’t know, I was just watching Reddick go out there and set the pace,” Byron said when asked how he gained so much time between the first and second rounds. “He’s been so fast all weekend. Just trying to continue to inch up on him.
“We made big improvements with the car overnight. I thought that practice session (Friday) helped us to get a little bit better and get the back of the car settled down.
“It’s really fun to get the first pole of the year. Obviously, we’ve been on a good stretch here of late. Tomorrow’s what pays. So, we just got to be there at the end.”

Harrison Burton’s last time was disallowed for short-cutting the esses during his lap.

Jones rocketed to the top of the speed chart with an average lap speed of 93.227 mph, which already broke the track qualifying record.
“Man, it felt good,” Jones said. “I hope in the second round we can do it again. Nice to be quick on a road course. It’s not something that has always come easy for me.”
Byron ended up second-fastest (93.179 mph) and Allmendinger was third (93.098 mph).
