For the first time in NASCAR history, Nashville Superspeedway will host a Cup series event when the green flag drops on the Ally 400 on 3:30 p.m. ET on Sunday. Kyle Larson is at 5-2 odds by William Hill Sportsbook to win the debut Cup race at Nashville after winning the All-Star Race at Texas last week. This week, Larson will be attempting to become just the fifth active driver to win three consecutive Cup races. Brad Keselowski last pulled off the feat in September of 2018. 

Larson is 47 points behind leader Denny Hamlin in the Cup series standings heading into Nashville, yet he is just one of two drivers to record three wins this season and seems destined to pass Hamlin very soon. He has led the highest percentage of miles (29.2) and laps this season in the series (27.08). Larson is also second in driver rating with a 109.8 mark.

Before you make any 2021 Ally 400 picks, you NEED to see what SportsLine's Micah Roberts has to say. Roberts, a former Vegas bookmaker, was the first to offer expanded NASCAR betting, and now hands out NASCAR winners to his followers on SportsLine.

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. 

Anyone who has followed his picks is up HUGE year after year.

Now, Roberts has analyzed Sunday's 2021 Ally 400 starting grid. We can tell you he's not seeing Martin Truex Jr. as a top play, even though he's one of the favorites. In fact, Roberts says Truex Jr. barely cracks the top 10!

Instead, Roberts is high on a long shot who is among the best drivers in terms of top-10 finishes! This driver is being underestimated by oddsmakers, and anyone who bets on him could hit it BIG. You ABSOLUTELY need to see who it is before making any picks.

So who wins the Ally 400 on Sunday? And which enormous long shot stuns NASCAR? ... Join SportsLine right now to see Micah Roberts' full projected leaderboard for the Ally 400, all from the nation's premier NASCAR betting expert!
