Corey Day and William Sawalich have spent much of 2026 crossing paths. After consecutive incidents at Darlington and World Wide Technology Raceway, the tension between two of NASCAR’s top young prospects is becoming difficult to ignore.
But this didn’t start at Gateway.

Their first notable run-in came at Daytona in February, when contact from Day triggered a multi-car crash that ended both of their races. NASCAR has also pointed to an interaction between the two at Circuit of The Americas.
By Darlington, Day described their hard racing as an “ongoing thing all year long,” while acknowledging earlier incidents he had apologized for.
On Lap 68, contact while battling sent Sawalich into the wall and eventually ended his race. The two disagreed over who was responsible, and their post-race conversation solved little. Day said Sawalich threatened to wreck him and told him, “We’ll see how the rest of your Chase goes.” Sawalich denied planning retaliation.
One week later, they were together again at Gateway.

After contact while racing near the top five, Sawalich moved left into Day’s Chevrolet on the backstretch, sending Day across Justin Allgaier’s car and hard into the inside SAFER barrier. Allgaier called the move “retaliation.”
The crash also carried championship consequences. Day entered Gateway fifth in the Chase standings and left eighth, 69 points behind the lead.
What makes this worth watching beyond Bristol, though, is where these two could be headed.
Day, 20, recently signed a long-term extension with Hendrick Motorsports and will make his Cup Series debut in 2027. Sawalich, 19, is a Toyota Development Driver who has already re-signed with Joe Gibbs Racing for next season.

This isn’t Hendrick versus Gibbs or Chevrolet versus Toyota. But it is two highly regarded prospects climbing NASCAR’s ladder through competing powerhouse pipelines.
One rough stretch doesn’t guarantee a lasting rivalry. But Daytona established history. Darlington made it personal. Gateway escalated it.
And considering how young Day and Sawalich are, NASCAR fans could be watching the beginning of a story that follows them much further up the ladder.
