William Byron led the way for NASCAR Cup Series playoff contenders at Kansas Speedway with a runner up finish in the Hollywood Casino 400.

Ross Chastain won the race, which means no playoff driver clinched a spot in the postseason’s third round. Chastain took the lead from the front row on the race’s final restart with 20 laps go. Byron took second place just as quickly, but the Hendrick Motorsports driver couldn’t overcome the leader’s advantage and never got to Chastain’s bumper to mount a challenge.
