Haiden Deegan cruised to victory in the 250 East/West Showdown at The Dome at America's Center in St. Louis, Missouri, clinching his second consecutive Supercross championship. Deegan's sixth career Supercross title came with a margin of over 15 seconds, as he continues to pull away in the combined SuperMotocross World Championship standings.

Why it matters

Deegan's championship-clinching performance in St. Louis further cements his status as one of the top young talents in motocross racing. At just 21 years old, he has now won six Supercross titles, including back-to-back crowns, solidifying his position as the dominant force in the 250 class.

The details

Deegan led from the sixth lap onward, passing his Yamaha teammate Cole Davies, who had grabbed the holeshot. Davies finished second, while Kawasaki's Seth Hammaker rounded out the podium in third. Nate Thrasher and Ryder DiFrancesco completed the top five. Deegan's sixth win of the season came despite a penalty for cutting the track in Birmingham earlier this year.

  • Deegan clinched his second consecutive Supercross championship with the St. Louis victory.
  • The 250 West riders have one standalone race remaining at Denver, Colorado, in the penultimate round of the season, and they will close with the final Showdown in Salt Lake City.
