Reddick and William Byron spent much of the race trading the lead but Reddick moved out front for the final time on Lap 64 of what was originally scheduled as a 68-lap race.
To preserve the win, however, Reddick had to fight off repeated challengers in three two-lap overtimes to claim the victory in Sunday’s race at COTA, his first win driving 23XI Racing’s No. 45 Toyota.
On the final restart with Reddick in the lead, Kyle Busch got into Alex Bowman entering Turn 1 which helped Reddick clear for the lead and he made it to the white flag without any further incidents on the track.
Reddick ended up claiming the win over Busch by 1.411 seconds to earn his fourth career win, three of which have come on road courses.
The win continues a remarkable turnaround for Reddick, who began the season wrecking out of the first two races.
“It means the world. This whole 23XI team has been working so hard all winter long to make the road course program better. Was extremely motivated to come in here and prove that performance, too,” Reddick said.
“Toyota, everybody, all the resources they’ve been putting into this to help turn around the road course program means a lot. I’m out of gas.
“Unfortunately, we had some problems with the cool shirt. I felt that today. I screwed up Turn 1 about every single time. It’s good to turn it around and make it better at the end.”
Bowman finished third, Ross Chastain fourth and Byron wound up fifth.
Completing the top-10 were Austin Cindric, Ricky Stenhouse Jr., Chris Buescher, Ty Gibbs and Todd Gilliland.
Among the road course “ringers” who participated in Sunday’s race, former Formula 1 champion Jenson Button had the best finish of 18th.
Sportscar star Jordan Taylor, substituting for the injured Chase Elliott was 24th and former Formula 1 champion Kimi Raikkonen received a penalty for short-cutting the track on the final lap and ended up 29th.
As the final stage got underway, Reddick remained in the lead.
On Lap 31, Gibbs was assessed a pass-through penalty for short-cutting the esses part of the track.
Kyle Larson was among a handful of drivers who elected to pit under green after the start of the final stage but was penalized for speeding and had to serve a pass-through penalty.
Reddick made a green-flag stop on Lap 32, which handed the lead over to Buescher.
After Buescher made a green-flag stop, Byron cycled back into the lead on Lap 33.
On Lap 34, Gibbs was again penalized for short-cutting the esses part of the track and had to serve another pass-through penalty down pit road.
On newer tires, Reddick got around A.J. Allmendinger on Lap 37 to move into the second position, 1.5 seconds behind Byron.
Reddick finally caught Byron off Turn 1 on Lap 3, quickly got around him on the inside and returned to the lead.
