2020 Toyota 500: Top DraftKings daily Fantasy picks from a NASCAR insider

Before setting your NASCAR DFS lineups for Wednesday's 2020 Toyota 500 at Darlington Raceway, you'll want to see what NASCAR insider Matthew Mayer has to say. Mayer, a NASCAR writer at CBSSports.com and producer for CBS Sports HQ, has been covering NASCAR for years and has delivered consistent winning lineups in DraftKings.

Mayer cashed in multiple lineups in each Cup Series race before the hiatus and came back strong in NASCAR's return to action, finishing in the top four percent of lineups in the million-dollar contest at the 2020 Real Heroes 400. Now, he's looking to keep his hot streak going on Wednesday.

For the 2020 Toyota 500 on Wednesday evening, Mayer says Jimmie Johnson ($9,100 on DraftKings) and William Byron ($8,900 on DraftKings) are absolute must-plays. Both will have the opportunity to capitalize on the position differential after suffering misfortune in the early part of Sunday's race.

Byron won Stage 1 on Sunday before encountering issues while Johnson was in position to win the stage before crashing out of the race. Both drivers race for Hendrick Motorsports, which delivered two top-5 finishers on Sunday in Alex Bowman and Chase Elliott. 

Mayer is also targeting an undervalued driver who could return huge value. He comes at a cost that balances the high-priced drivers, but also has a legit chance of finishing inside the top 10. This driver could be the difference between cashing in your tournaments. 

So what are the top NASCAR DFS lineups for the 2020 Toyota 500? And which value driver is a must-roster? ... Join SportsLine right now to see NASCAR insider Matthew Mayer's top picks for DraftKings, and cash big on NASCAR at Darlington!
