Allgaier had to hold off veteran Martin Truex Jr. – who had dominated most of the race – over the final 11 laps but held on to win Saturday’s EchoPark 250 at Atlanta Motor Speedway.
It had been a tough start to the season for Allgaier, who had wrecked out of a pair of races and only collected his first top-10 finish last weekend at Phoenix.
The win all-but locks Allgaier into this year’s playoffs, basically giving him a reboot to his season.
Once his exited his JR Motorsports No. 7 Chevrolet, Allgaier immediately dedicated the win to William “Rowdy” Harrell, a well-known Hendrick Motorsports and JRM crew member who tragically died in an automobile accident last November.
Allgaier said he was well aware he was going to have to hold off Truex – who got shuffled to the rear of the field late in the race due to a pit road speeding penalty – to have a shot at the win.
“I knew Martin was going to be coming at the end of the race there. I didn’t know if I needed to do anything different. I didn’t know if there were any options that I needed to change my line (around the track),” Allgaier said.
“It’s really special. We’ve not been to Victory Lane since we lost Rowdy. It’s been an emotional time as much as anything. We put ourselves in the right spot and ultimately it worked out for us.
“This sport is so humbling. It’s so hard to get to Victory Lane. This team does an incredible job. We have not fired off at the beginning of the season like we wanted to.
“The effort really has been great; pit stops have been fantastic.”
While Allgaier was celebrating his win with a burnout on the frontstretch, drivers Noah Gragson and Daniel Hemric got into a fight on pit road over an incident that happened earlier in the race during pit stops.
Harrison Burton finished third, Gragson fourth and A.J. Allmendinger rounded out the top-five.
Completing the top-10 were Riley Herbst, Michael Annett, Justin Haley, Hemric and Ryan Sieg.
