Kyle Busch did not earn a berth in the NASCAR Cup Series postseason, but his Richard Childress Racing team took another step forward at Darlington Raceway on Sunday.

Busch had an average running position of 14th but charged late in the Southern 500 to get to second place behind Chase Briscoe. The two-time Cup Series champion had a tire advantage on Briscoe, having pitted during a rash of late cautions, but he was unable to mount a serious challenge for the lead.

It was his second consecutive runner-up effort, and fifth top-five on the season. Busch needed a win to get a place in the postseason.
