The 2026 NASCAR In-Season Challenge kicks off on Sunday at Sonoma Raceway with the Toyota/Save Mart 350. The race is set to begin at 3:30 p.m. ET, featuring Denny Hamlin as a +500 favorite despite ending his three-race win streak last week. However, for this event, Hamlin finds himself as a +10000 longshot in the odds, while reigning champion Shane van Gisbergen stands as the -150 favorite.

In addition to van Gisbergen, two other drivers to watch include Tyler Reddick and Connor Zilisch, both at -750 odds. Notably, Daniel Suarez, a former winner at this track, enters as a +6000 longshot, presenting an intriguing option for those considering NASCAR Sonoma DFS picks.

Mike McClure, a renowned professional DFS player, offers insights from his advanced prediction model, which has successfully predicted 30 winners since 2021. He has previously backed Hamlin's recent victories, making his analysis essential for fans and bettors alike.

For this race, McClure advises against betting on Ryan Blaney, who sits at +1200. His past struggles at Sonoma, including a 36th place finish last year, raise concerns about his potential performance. Conversely, AJ Allmendinger, with odds of +3300, is a strong candidate as he has secured two top-6 finishes in his last three Sonoma outings and is coming off a fifth-place finish in his most recent race.

McClure also highlights three longshot drivers over +4000 who could surprise at the top of the leaderboard, including one massive longshot exceeding +7500, promising significant returns for those willing to take the risk.
