Chase Briscoe wins at Darlington to clinch NASCAR playoff spot #nascar

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 left in the regular-season finale at Darlington Raceway and held off Busch, who, like Briscoe, needed a victory to reach the postseason.

"We just won the Southern 500," an emotional Briscoe said on his radio.

Briscoe's Stewart-Haas Team announced its closure earlier this season. Briscoe gave the proud program something to fight for over the final 10 weeks of the season.

"Yeah, this group, the day we found out that the team wasn't going to exist anymore, we went over to the shop board, looked at each other and said, 'We're in this to the end,'" Briscoe said. "I was saying all week, 'We've got one bullet left in the chamber.' That bullet hit."
