King of America X powered by Summit

 Finished 9th on Friday
 Finished 28th on Saturday

 The Summit USMTS National Championship fueled by Casey’s invaded the Humboldt Speedway for King of America X powered by Summit. Three nights turned into two nights and a morning matinee thanks to Mother Nature. On Friday night, Zack finished second in his heat race after starting fourth. In the main event, he drew the dreaded No. 8 and started outside of the fourth row, eventually bringing home a ninth-place finish. On Saturday night, he went from fifth to fourth in his heat and then fought his way from fourth to finish second in the second “B” Main, which qualified him for his tenth straight King of America main event. After starting 18th, Zack was able to complete just 18 laps before retiring from the race in 28th, thus ending a streak of nine top-15 finishes or better in a row.

 Finished 20th on Friday
 Finished 14th on Saturday

On Friday, Zack finished sixth in his heat race but bounced back to pass five cars and finish fourth in his "B" Main. He started 20th in the main event and that's where he stayed. On Saturday, things improved with a solid heat win and then an outside third row starting spot for the main event. Struggling with mechanical issues, however, relegated 'The Z-Man' to a 14th-place finish at the end of the 40-lapper.
