Organizational Structure

Each LDB franchise has three tiers: Majors, AAA, and AA.

Majors

The Majors level is a 25-man roster and represents the active players on the team whose performance may affect scoring. It closely resembles an MLB franchise. All 25 players are available for active duty, and are broken down into the following positions:

Hitters	Pitchers
Catcher	Starting Pitchers (5)
First Base
Second Base
Short Stop
Third Base	Relief Pitchers (6)
Left Field
Center Field
Right Field
Designated Hitters (2)
Bench (4)
Disabled List (3)

Positional Eligibility

Hitters

For hitters, a player is eligible for a position if (1) that player made 20 appearances in that position during the previous season or (2) the player appeared at that position for 50% of games in April of the current season, or, after April, appeared at that position a total of 15 times during the season. Until a hitter meets one of these thresholds, he may bat as a designated hitter only.

Pitchers

For pitchers, to be eligible as a starting pitcher, a player must have appeared as a starting pitcher in five games during the previous season or three games in the current season. To be eligible as a relief pitcher, a player must have appeared as a relief pitcher in ten games during the previous season or five games in the current season. Until a pitcher meets one of these thresholds, he may pitch as a relief pitcher only.

Disabled List

A player in the Majors is eligible to be on the Disabled List (DL) when he is on the MLB DL. See Internal Transactions for other rules related to the DL.

AAA

The AAA tier is a roster of any seven players, hitters or pitchers. See Internal Transactions for rules relating to service time and waivers, which may affect a team's choice to promote from, or demote to, AAA.

AA

The AA tier is a roster of unlimited rookie players signed in the AA draft. See Internal Transactions for rules relating to the consequences of promoting a player out of AA.
