A bit of context

Seattle 2026 came with a storyline twist: Cooper Webb had won the last two Seattle Supercross rounds, but this time Eli Tomac chased him down and claimed the top step. Tomac’s win helped reinforce his status as a major title threat early in the 2026 season.

In 250SX, Max Anstie’s victory marked a strong return to the top step after earlier-season success at Anaheim, showing he’s still very much in the mix for the Western Regional points fight. Fans have been buzzing on forums about whether this signals a momentum swing in both classes heading into the next rounds.
