John McDonald was having a great night Saturday at North Star Speedway until a flat tire ruined his evening.
In the first heat of the featured sprint cars, McDonald set a track record with a qualifying run of 9.3 seconds on the paved quarter-mile oval.
McDonald was leading the feature race when he blew a tire going into the final turn.
Tyler McDonald wound up the sprint winner after taking the second heat and the finale.
In the legends class, Andy Workman didn't win a heat but claimed the feature race over Mike Thomas, the second-heat winner.
Keith Jones did the same in the thunder stocks, outracing Stephen McElroy.
Coming up Saturday, North Star Speedway is hosting the 49th State Street Hot Rodders and Burnout competition.
