Step 1: Roster

Enter each player's name and assign a tier. Tier 1 = strongest, Tier 2 = developing, Tier 3 = beginners.

Team Name

Players (0 added)

Step 2: Game Format

Set the game length and field configuration. EH slots are calculated automatically.

Number of Innings

Field Positions

Outfield Format

EH Slots per Inning

–

Roster size minus field positions. Updates automatically.

Step 3: Game Priority

How should the lineup balance development and winning?

MODE 01

Win Mode

Tier 1 stays at premium IF positions. Tier 2/3 rotate through OF and EH.

MODE 02

Balanced

Tier 1 gets IF priority but Tier 2 gets meaningful IF reps.

MODE 03

Development

Everyone rotates through IF. 3B used as a development slot.

Step 4: Pitching

Assign pitchers to innings. One pitcher per inning by default.

Pitcher per Inning

Pitcher sits EH the inning before pitching: gives them a rest before taking the mound.

Allow a pitcher to throw 2 innings: useful when you have one strong arm or fewer pitchers. Always stay within your league's pitch count and rest-day rules (Little League, or MLB and USA Baseball Pitch Smart).

Emergency Pitcher #1

Emergency Pitcher #2

Step 5: Catching

Assign catchers to specific innings. You can use up to 3 different catchers.

Catcher per Inning

Step 6: Position Rotation Rules

Control where your Tier 1 and Tier 2 players go.

Tier 1 Infield Positions

Which IF positions should Tier 1 players rotate through?

Tier 1 Max Outfield Innings

3B as development slot: rotate a different Tier 2 player to 3B each inning.

Step 7: EH and Bench Rules

Control how sitting time is distributed.

Max Times a Player Can Sit (EH)

Tier 1 players never sit: they are in the field every inning.

Auto-distribute EH slots evenly across Tier 2 and Tier 3 players.

Step 8: Special Rules (optional)

Player-specific locks and inning-specific overrides.

Player Locks

e.g. "Will plays IF only" or "Maya must play CF every inning"

Inning Overrides

Force a specific player to a specific position in a specific inning.
