Cindric ran strong throughout the race but took the lead for the first and only time on with 50 of 200 laps remaining and cruised to a 3.796-second win over Josh Berry.
Cindric went to the inside of Justin Allgaier in Turn 2 and the two drivers made contact as Cindric cleared for the lead.
The win is Cindric’s third of the season, 11th of his career and first at Dover (Del.) International Speedway.
“I’m fired up, man,” Cindric said after the win. “I love this race track more than anywhere else we go to. I hate to admit it – but I love it! I’m glad we got it done today.
“Every win means so much and everyone that is in this series – I have the unique opportunity to know what I am doing in the future. I respect the guys that I am racing around are trying to get to the top level. I know I have that for me down the road but I have to bring that same energy that I am racing against.
“These wins are really hard to come by. It sucks that we have had some bad races recently that make this one feel so much better. This is my favorite race track that we go to.”
Allgaier ended up third, A.J. Allmendinger was fourth and Ty Gibbs rounded out the top-five.
Completing the top-10 were Harrison Burton, Michael Annett, Ryan Sieg, Daniel Hemric and Brandon Brown.
Berry, as the highest finisher among the four eligible drivers, took home the final $100,000 Dash 4 Cash bonus of the 2021 season. Noah Gragson had collected the bonus in the first three races it was available.
“It could have been one spot better,” Berry said. “We were so good today. That last run we fired off a little too free, kind of got ate up and me and Justin got to racing each other and (Cindric) got away.
“We just weren’t quite as good in that last run as we were the one before. It’s my race here. There’s a lot to be proud of.”

“We’ve got a really fast Camaro, but we’ve got three others in the field that are equally as good,” Allgaier said during the break. “Josh is doing a fantastic job, gave him some room and we raced it out.
“This is not an easy place, but it’s a fun place.”
