Erik Jones held off Danny Hamlin in a 20-lap sprint to the finish in the first playoff race to win for the second time at Darlington last weekend - continuing a chaotic NASCAR season.
Jones became the first non-playoff driver to win the first postseason race since the format was established in 2014.
Pole-winner Joey Logano moved into first in the postseason standings by six over William Byron and eight over Hamlin. Kyle Busch led a race-high 155 laps, but suffered a blown engine as he prepared for the final restart. He wound up 30th.
Kyle Larson won from the pole position last year on his way to the Cup Championship.
Practice and qualifying for the Cup series is at 11 am Saturday and the green flag waves at 2 pm on Sunday.
