Keselowski’s day began from the 13th position following his qualifying effort Saturday, and he, too, charged to the front early. The BuildSubmarines.com Ford was 10th just 29 laps in, eighth 30 laps later, and went on to finish ninth in the opening stage of 70 laps.
He fired off sixth for stage two, but from there quickly drove forward to third by lap 101. His first green-flag stop of the day came at lap 122 with his teammate, as he cycled to the third spot by lap 145. Another pit cycle gave him the lead by lap 182, before he went on to win stage two with RFK taking the top two spots.
They restarted in the same positions and maintained until the next green-flag cycle, this one at lap 284. Keselowski pitted from the lead and nearly overshot his pit box, losing just enough time to relinquish the lead.
He later regained the top-five position and maintained the spot throughout, before going on to finish sixth in a race that saw just the one natural caution with nine to go.
