— Chase Briscoe went three-wide to pass Kyle Larson and Ross Chastain for the lead, then outran two-time series champion Kyle Busch to win the Southern 500 on Sunday night and make the NASCAR Cup Series playoffs.
Briscoe pulled away on a final restart with 17 laps in the regular-season finale at Darlington Raceway and held off Busch, who, like Briscoe, needed a victory to reach the postseason.
