Reasoning
Standard MLB season outright (World Series winner). Domain is sports - seasonal tournament winner. Pinnacle offers comprehensive MLB futures including World Series champions. Resolution date aligns with typical MLB postseason conclusion (late October 2026). Outcome is binary (Mariners win or don't win). High confidence for Class A match - this is a canonical sports betting question with straightforward resolution criteria and official MLB source.
