William Byron Jr. will try to make it back-to-back wins to start the 2025 season when the NASCAR Cup Series turns its attention to Sunday's 2025 Ambetter Health 400 at Atlanta Motor Speedway. The 27-year-old earned his second consecutive Daytona 500 victory last week and will try to improve on his two Atlanta finishes from a year ago. He followed up his Daytona win a year ago with a 17th-place finish at the Ambetter Health 400 and also finished ninth at the Georgia track later in the season. The Hendrick Motorsports racer has run 253 races over seven years, earning 14 NASCAR Cup Series wins with 105 top-10 finishes.

Ryan Blaney is the +750 favorite, followed by Joey Logano (+1000), Kyle Busch (+1100), and Austin Cindric (+1200) in the latest 2025 Ambetter Health 400 odds. Sunday's 2025 NASCAR at Atlanta Motor Speedway race is scheduled to start at 3 p.m. ET. 

Before making any NASCAR at Atlanta picks, be sure to see what CBS Sports NASCAR writer Steven Taranto has to say.

Taranto, who moonlights as a sim racer and has 20 career wins in iRacing, is the lead NASCAR writer for CBSSports.com, and he chronicles stock car racing with the same thoroughness and passion that he's had since becoming a full-time race fan in 2001. He has an annual NASCAR media credential and also publishes a popular weekly NASCAR predictions column, famously calling Ross Chastain and Daniel Suarez's breakthrough wins in 2022. Taranto was red-hot for SportsLine in 2024 as he nailed 17 winners, including 16-1 longshot William Byron at the Daytona 500 and 14-1 longshot Chase Elliott at Texas. Anybody following his NASCAR picks has seen HUGE returns!

For the 2025 Ambetter Health 400, Taranto is high on veteran Cup driver Joey Logano. Another curveball: He's fading Denny Hamlin, who placed 24th at last week's Daytona 500. "We all know that Denny Hamlin is one of NASCAR's very best when it comes to drafting and finding his way to the front on superspeedways, with the shot he had to win his fourth Daytona 500 on the final lap a week ago serving as the latest evidence of that. So far, however, all the success Hamlin has had in his career at Daytona and Talladega has not carried over to Atlanta following the track's reconfiguration," Taranto told SportsLine.

Taranto also locked in four more Ambetter Health 400 best bets and is high on a MAJOR dark horse who is going off at more than 50-1! You ABSOLUTELY NEED to see his picks before locking in any NASCAR picks of your own.
