Logano raced to series-leading victory of the season Saturday, winning for the 16th time in NASCAR's second-tier circuit.
Paul Menard was second, followed by Michael Arnett, points leader Elliott Sadler and Kyle Busch.
Logano swept the Dover races this season. He powered his way to the lead with six laps left in the June race. This win was easier. He led all but the early laps in the No. 18 Toyota.
