For the first time in 10 years, NASCAR will return to Nashville Superspeedway, as the green flag will drop on the 2021 Ally 400 on Sunday at 3:30 p.m. ET. However, this will be the first-ever Cup series event at the site. Kyle Larson is the favorite at 5-2 to win in the latest 2021 Ally 400 odds from William Hill Sportsbook and the most recent driver to win a Cup race on Father's Day (2017). Larson has no past experience at Nashville, while there are 14 other drivers who have significant experience at the site.

Kyle Busch, listed at 15-2 in the 2021 Ally 400 odds at Nashville Superspeedway, looms large when it comes to success in Music City. Busch won the Xfinity race at Nashville on Saturday, marking the fourth time he has won on NASCAR's longest concrete oval in the Xfinity and Truck series combined. Other top 2021 Ally 400 contenders for NASCAR at Nashville include Martin Truex Jr. (5-1) and Denny Hamlin (6-1). You'll want to check out the NASCAR at Nashville predictions for the Ally 400 from Micah Roberts, the legendary Vegas bookmaker who pioneered wagering on racing, before locking in any 2021 Ally 400 picks.

Roberts is the nation's premier NASCAR betting expert, and his top pick, Larson, won the Coca-Cola 600 in the final event of May at 11-2 odds. He also correctly predicted the EchoPark Texas Grand Prix the previous week, hitting Chase Elliott's win at 8-5 odds.

He began a stretch of three winners in six races on Apr. 25, when he nailed Brad Keselowski's win in the GEICO 500 at 14-1 odds.

Roberts correctly called the first two races of the 2020 season and also enjoyed success the previous year, as his top four choices in each race during the 2019 NASCAR campaign returned a head-turning $3,400 to those who put down $50 on each. In addition, he has correctly predicted at least six top-10 finishers in nine of the last 14 races of the 2021 campaign. 

Now, Roberts has analyzed the field and odds for Sunday's NASCAR at Nashville 2021 race. He's sharing his winner and leaderboard right here.

2021 NASCAR at Nashville expert predictions

One shocker: Roberts is not backing Martin Truex Jr. as a top contender in the Ally 400 2021 even though he had two top-five finishes at Nashville in the Xfinity Series and led for 105 laps in his last race at the site. In fact, Roberts says Truex, who is third in driver rating overall this season at 102.4, barely cracks the top 10 on his projected Ally 400 leaderboard. 

"His three wins using this week's race package are the most among all drivers, but those wins came in the first six races using it. In the three races since Darlington using the package he had poor finishes at Dover and COTA and finished third at Sonoma two weeks ago," Roberts told SportsLine. "My thinking now is that all Hendrick drivers should be favored over Truex."  

Another curveball: Roberts is high on Joey Logano, even though he is listed at 12-1 in the latest NASCAR at Nashville odds 2021. Logano is fourth in driver rating at 100.5 and has a Nashville Xfinity win to his credit.

"All this guy does is get top-five finishes in the 750 HP package, with the lone trophy coming at the Bristol Dirt Race. He has seven top-fives, including the last three using this week's package," Roberts told SportsLine.

How to make 2021 Ally 400 picks

Roberts is all over a long shot who can become the latest winner from a team that is surging recently. This driver is being underestimated by oddsmakers, and anyone who backs him could hit it big. You can only see who it is here.
