The inaugural NASCAR in‑season challenge tournament kicked off at Sonoma Raceway, drawing a full field of competitors eager to test their mettle early in the season.
Top seed Tyler Reddick entered the first‑round matchup as the favorite, but his run ended abruptly when Alex Bowman, seeded 32nd, delivered a decisive victory.
Meanwhile, veteran Denny Hamlin, seeded second, navigated a sudden spin and damage to his splitter, yet managed to hold on and defeat Ty Dillon.
The first round produced a surprising shake‑up, as Reddick and Daniel Suarez were the only drivers among the top‑10 seeds to be eliminated, underscoring the unpredictability of the format.
