Chris Buescher, Keselowski's team-mate at RFK Racing, was working feverishly to hold off Reddick in the final laps when Reddick got into him as he attempted a slide job off Turn 4 and the two collided.
That collision – which sent both drivers to the pits with flat tyres – opened the door for Keselowski to inherit the lead with eight of 293 laps remaining, and he held off Ty Gibbs by 1.214 seconds to clinch the victory.
