Darrell Wallace Jr. — who has raced well at the superspeedways — at 80/1 may be too good to pass up.NASCAR XFINITY SERIES: MONEYLION 300 (113 laps, 300.6 miles around a 2.66-mile D-shaped oval), Talladega Superspeedway; Lincoln, Ala.TV: Saturday, 1 p.m. ET (Green flag approx. 1:18 p.m. ET) — FS1 (Radio: Motor Racing Network, SiriusXM NASCAR Radio Channel 90).THIS WEEK: The ninth of 33 races on the season, the drivers go from a short track at Richmond to the mammoth Talladega Superspeedway and the use of tapered spacers on the engines. … This will be the 28th series race at Talladega. … Cole Custer won at Richmond, the second win of the season for the 21-year-old Stewart-Haas Racing driver. … Spencer Gallagher won this race last year. … Tyler Reddick leads the Xfinity standings with 362 points, followed by *Christopher Bell (338), *Custer (333), Austin Cindric (299), Justin Allgaier (275), John Hunter Nemechek (263), *Michael Annett (262), Chase Briscoe (255), Ryan Seig (253) and Noah Gragson (246).*Denotes race winner and playoff berth.
