After starting from the pole in race one, Linker jumped out to the lead but was overtaken by Glenski on lap three.  The two went back-and-forth with Linker going back out front on lap 21, before Glenski fought back to take the lead for the final time one lap later.  Glenski led the rest of the way for his third win of the season over Linker, 2021 track champion Matt Cox, Casey Kelley, and RA Brown. 

For race two, the top seven finishers were inverted putting Kade Brown and Justin Milliken on the front row.  Milliken stumbled on the start, allowing Kelley to make it three-wide for the lead entering turn one.  Kelley would lead until lap 10 when RA Brown moved to the front.  RA Brown continued to lead until lap 31 when he and Linker slammed doors on the frontstretch.  Linker went on to lead the rest of the way for his first win of the season over RA Brown, Glenski, Cox, and K.
