NASCAR In-Season Tournament updated bracket: Round of 4 locked in after Sonoma

The NASCAR In-Season Tournament bracket has been updated following an exhilarating weekend at Sonoma Raceway in California. Sparks flew at the end of the Toyota/Save Mart 350, as Ty Dillon bumped Alex Bowman out of the way on the final lap to advance to the Round of 4.

Now, he’ll be matched up against John Hunter Nemechek. On the other side of the bracket, Tyler Reddick will face Ty Gibbs in what should be a doozy of a showdown. Dover International Speedway will be the cathedral for the Round of 4.

Dillon has been the star of the In-Season Tournament, the very last seed making a miraculous run to the Round of 4. His victory over Bowman didn’t come without controversy, as the duo shared words on pit road following the last-lap incident. Dillon’s team in Kaulig Racing shared a video of the conversation, with Dillon and Bowman sharing an awkward handshake at the end.

Prior to moving past Bowman, the No. 32 seed in Dillon defeated No. 1-seed Denny Hamlin and No. 17-seed Brad Keselowski. Bowman previously the No. 8 seed. Winning the tournament and a cool million would be a huge boost for Dillon, who has yet to win a race in his Cup Series career.

In the process, the run Dillon has been on is getting a lot of attention. Along with defeating the top drivers in NASCAR, the 33-year-old has trolled Hamlin and Keselowski after winning. This led to NASCAR legend and FOX Sports analyst Kevin Harvick calling Dillon out for his actions.

“The bracket, there’s a little bit of luck involved in, no matter what racetracks we go to, but starting at Atlanta just turned it all upside down,” Harvick said on Kevin Harvick’s Happy Hour. “I mean, Ty Dillon is still in it.”

Harvick also shared his reaction to Dillon trolling Keselowski: “I just don’t know how you talk that much trash when you run that bad, though,” he stated. “I would just be more humble about it. I mean, if you were up there running first or second, third, fifth, something, and you’re knocking people out of the bracket, but you’re knocking the guys out that are crashing. Let’s not be cocky about it.”

All told, Dillon has earned one top-10 finish, which was eighth place at Atlanta. Maybe Harvick has a point. The Welcome, North Carolina native returned to full-time Cup Series racing this year after being part-time in 2024. In 249 Cup Series races, Dillon has finished in the top 10 seven times.

The rest of the competitors in the NASCAR In-Season Tournament Round of 4 are a little more polished. Tyler Reddick has to be the favorite at this point among the four. He’s the reigning regular season champion in the sport, and while he hasn’t found that same level of success in 2025, he’s still a major threat to win each weekend.

Time will tell who gets the better of one another in Dover, and which drivers advance to the finale. After a trip to Delaware, it’ll all come to a head in the Brickyard 400 at Indianapolis Motor Speedway. We’ll see if it’s Ty Dillon, John Hunter Nemechek, Tyler Reddick or Ty Gibbs standing tall at the end of it all.
