Erik Jones, a two-time Southern 500 winner, led Saturday’s Cup Series practice session at Darlington Raceway.
Jones topped the board at 166.461mph (29.542 seconds). He set the fastest time on his first lap on track.
Denny Hamlin was second fastest at 166.146mph and Ricky Stenhouse Jr. was third fastest at 166.118mph. Stenhouse then brought out a brief caution early in practice.
The back end of Stenhouse’s car came around through Turn 4, putting him into a slide before he eventually lost control of the car at the corner exit. Stenhouse spun down the frontstretch and hit the inside wall.
