Wii Sports Baseball: Can You Pick Your Team? No, But You Can Influence It
In Wii Sports Baseball, you cannot select specific Miis or create a custom roster for your team in the standard gameplay modes.
How Team Assignment Works
Single Player: You control the batting team (your Miis from the Mii Plaza/Parade). The fielding team is composed of CPU Miis (randomly selected from your Plaza/Parade or default "Matt", "Miracle", etc.).
Two Players (Versus): Player 1 = Batting Team (their Miis). Player 2 = Fielding Team (their Miis).
Mii Selection: The game pulls the first 9 Miis from your **Mii Plaza** (or Mii Parade if Plaza empty) to form the 9-player lineup. You cannot reorder the batting order or choose bench players.
What You *Can* Influence
Mii Physical Stats: Height/Weight set in Mii Channel affect hit power and running speed slightly.
Mii Plaza Order: Arrange your favorite 9 Miis at the front of your Plaza (drag/drop in Mii Channel) to set your default lineup.
Skill Level: As you win, the CPU "Pro" level increases (indicated by ⭐ next to Mii name), making opponents tougher.
So while you can't "draft" a team, curating your Mii Plaza lets you field your preferred avatars.
