When Ryan Blaney won at Atlanta Motor Speedway in March, he extended the longest winning streak by a manufacturer at the site, the fifth consecutive win by Ford dating back to 2017. Kevin Harvick and Brad Keselowski had each won twice in the previous four NASCAR Cup Series events at Atlanta. When the green flag drops on the 2021 Quaker State 400 on Sunday at 3:30 p.m. ET, Ford will attempt to end a 10-race winless streak this season, with its last victory this season coming in late April. Chevrolet has the most all-time wins at Atlanta with 40, followed by Ford with 34.

Harvick, who is listed at 8-1 in the latest 2021 Quaker State 400 odds from William Hill Sportsbook, may give Ford its best chance to win, as he is eager to score his first victory of the season. Harvick, who is tied for the most all-time wins among active drivers with three, has the highest all-time driver rating (101.4) and fastest laps run (606) ever at Atlanta. You'll want to check out the NASCAR at Atlanta predictions for the Quaker State 400 from Micah Roberts, the legendary Vegas bookmaker who pioneered wagering on racing, before locking in any 2021 Quaker State 400 picks.

Roberts is the nation's premier NASCAR betting expert, and his top pick, Chase Elliott, won the Jockey Made in America 250 last week at 2-1 oddsHe also correctly predicted the Coca-Cola 600 winner in the final event of May, hitting Kyle Larson's win at 11-2 oddsThe previous week, he was on point at the EchoPark Texas Grand Prix, targeting Elliott as the winner 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 10 of the last 16 races he has projected during the 2021 campaign. 

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

2021 NASCAR at Atlanta expert predictions

One shocker: Roberts isn't high on Blaney, who earned his first-ever win at Atlanta Motor Speedway earlier this season. In fact, Roberts says Blaney, who needs a win to clinch a playoff berth with just six races left in the regular season, doesn't even crack the top five on his projected 2021 Quaker State 400 leaderboard.

"Blaney has had his best Atlanta runs the last two seasons with a fourth-place finish last season and a win in March when he led only 25 laps," Roberts told SportsLine. "He basically stole the race from Larson, who led 259 laps but lost speed down the stretch, with my guess being that Larson wore out his tires too early in the final run."

Another curveball: Roberts is strongly recommending Tyler Reddick, even though he is 65-1 in the latest NASCAR at Atlanta odds 2021. Reddick has two consecutive top-10 finishes and 10 in 20 starts this season.

"Reddick has had two mediocre finishes in his two Cup starts at Atlanta, but this week might be different," Roberts told SportsLine. "Expect his best line on the day to be the high-line, as he ran second at Homestead and seventh at Kansas."

Roberts is also high on another double-digit long shot who has "juicy odds" at Atlanta. This driver is being underestimated by oddsmakers, and anyone who backs him could hit it big. You can only see who it is here.
