This will be a truer test of the NASCAR Xfinity Series championship situation with Cup rookie Ryan Preece the only fulltime Cup driver entered in Saturday’s RINNAI 250 (2 p.m. ET, FS1, PRN, SiriusXM NASCAR Radio) – a race won the past six years by a Cup regular.

Defending series champion Tyler Reddick holds a five-point edge on his championship runner-up Cole Custer heading into Atlanta. Joe Gibbs Racing driver Christopher Bell arrives as statistically the top-ranked Xfinity driver at the track, after a third place showing in his Atlanta debut last year – a race won by Cup driver Kevin Harvick, who led a dominating 141 of 163 laps.

The entry list this weekend features a robust slate of Xfinity title contenders from Bell to Reddick and Custer. Talented young driver Austin Cindric will campaign a full-year in the Penske Racing No. 22 Ford. And perennial championship contender Justin Allgaier returns as well. Rookie Noah Gragson begins a season of high expectations and is coming off an 11^th place finish at Daytona.
