QUINCY, IL — July 8, 2018 — Taking the lead from Frank Heckenast Jr. just past the halfway mark, Brian Shirley of Chatham, IL, raced to his third DIRTcar Summer Nationals victory of the season and 18th of his career. In winning $5,000, the fourth-starting Shirley survived rugged track conditions that eliminated many of his competitors. Steve Roberts, who started sixth, ran in the top five throughout the 40-lapper before advancing to second in the waning laps for a career-best Summer Nationals finish. Polesitter Rusty Schlenk finished third.
