Haiden Deegan can clinch the 250SX West championship at the St. Louis Supercross Showdown on Saturday, April 4. He rides for Monster Energy/Yamaha Star Racing and enters the second 250SX East/West Showdown with a 42-point lead in the 250SX West standings, according to AMA Supercross standings. Only two West rounds remain after St. Louis — Denver and the season‑finale East/West Showdown in Salt Lake City — and 50 championship points will still be available; a Deegan victory with teammate Max Anstie finishing fifth or lower would mathematically secure the title. Levi Kitchen sits 47 points back, and a Deegan win in St. Louis would eliminate Kitchen and the rest of the field from contention.

The St. Louis Supercross Showdown is the 12th round of the Monster Energy AMA Supercross Championship and will be held at The Dome at America’s Center in St. Louis. The event is the second of three 250SX East/West Showdowns and counts as round six for 250SX East and round eight for 250SX West.

Qualifying airs on Race Day Live at 1:00 p.m. ET / 10:00 a.m. PT on Peacock, and full live coverage of the night program — including heat races, LCQs and main events — begins just after 7:00 p.m. ET / 4:00 p.m. PT on Peacock. International viewers can follow the same live timing via the SMX Video Pass (Spanish and French audio tracks), and SiriusXM will carry the complete night-show audio feed. Anstie has five finishes outside the top five this year, including a seventh-place result at the first East/West Showdown in Birmingham. Deegan has said he plans to move up to the 450 class for Pro Motocross; clinching the 250SX West title before that move would allow him to focus his preparation on the transition.
