Thirteen of 16 Chase drivers changed positions in the points following the Citizen Soldier 400 at Dover International Speedway.
Martin Truex Jr. won for the second time in three races and assumed the point lead. Defending Sprint Cup Series champion Kyle Busch moved to second in points. Truex and Busch are two of the 12 drivers moving onto the second round of the Chase, which begins next Saturday night at Charlotte Motor Speedway.
Kyle Larson fell out of the top 12 in points - allowing Austin Dillon to move into a transfer spot - and was eliminated from the Chase along with Tony Stewart, Jamie McMurray, and Chris Buescher.
