Established in 2001 with 28 teams, TBL expanded to 32 teams in 2011. Full league history is on StatsPlus.

5. Roster Rules

Each franchise fields teams across six minor league levels (AAA, AA, A+, A, A-, Rookie) plus an International Complex. GMs manage player movement, lineups, and rosters at every level. AI assistance can be enabled, but manual management is recommended — neglected minor league systems get a verbal warning first, but may be reorganized by the Commissioner if it continues.

LevelMax RosterAge Limit
Major League (ML)28 active (must be on the 40-man)
Triple-A (AAA)30No limit
Double-A (AA)30Under 28
Single-A Advanced (A+)30Under 26
Single-A (A)30Under 25
Low-A (A-)45Under 24
Rookie League45Under 22
International Complex60Ages 16–19 (IAFA / scouting)

Players who age out of a level mid-season must be moved by the GM to an appropriate level. Non-compliance results in the player being designated for assignment (DFA).

6. Postseason Format

The postseason features 8 teams from each conference (16 total), competing for the TBL Championship in a 7-7-7-7 game format. Ties for the final postseason spots are settled with a one-game playoff. Beginning with the 2030 season, the best overall record no longer earns a bye.

7. Acquiring Players

7.1 Trades

See Chapter 9, Trading, for the full rules.

7.2 Free Agency & Service Time

7.3 Amateur Player Draft

Conducted on StatsPlus starting in Spring Training (sim 7 of the off-season), with time limits per round. Draft order follows regular-season record, with ties broken by the previous year's standings. Draft-day trades are allowed, but only picks for picks — no players or cash. Drafted players join automatically.

7.4 Waivers

Waived players can be claimed within 15 in-game days. The claiming team takes on the player's salary and must have room on the 40-man roster.

7.5 International Amateur Free Agents (IAFA)

The IAFA pool releases annually at the start of the off-season with a $6 million soft cap. Exceeding the cap triggers a luxury tax and future limitations. Full rules are listed in-game.

7.6 Rule 5 Draft

Held annually; players under 23 are ineligible for selection. The deadline to protect players falls on the off-season's third sim (through 12/31). See the Rule 5 Draft Rules page for the full procedure.

8. Financial Structure

8.1 Budgets

8.2 Export Bonus

The export bonus is currently inactive but may return in the future.

8.3 Contracts

9. Trading

Use the in-game trade block, Slack's #tradeblock and #tradewants channels, the StatsPlus Trading Block, or direct messages to find a deal.

9.1 What Can Be Traded

9.2 Over-Budget Trades

Trades that push a team over budget are generally prohibited unless they're of equal value or improve the team's position. Starting at sim 7 of the regular season (around July 1st), a team may also make one over-budget trade per season if it has a winning record, is within 8 games of the division leader, and within 5 games of a playoff seed — meant to let teams go all-in on a title push.

9.3 Processing & Posting

9.4 Trade Deadline

The deadline hits before the regular season's 10th sim (the first sim in August of the in-game year). Trades must be confirmed before the deadline — invalid trades cannot be renegotiated afterward.

9.5 Unprocessed Trades

A trade can fail to process if a team exceeds its Total Money Available, the trade violates a rule or is improperly formatted, or a player exercises a no-trade clause or 10/5 rights. Unprocessed trades are noted in the sim announcement and must be reworked by the involved GMs; the sim upload doesn't wait on it.

9.6 Trade Veto

TBL has no blanket trade veto. The Commissioner can void a trade for collusion (including bad-faith trading between two parties), an involved GM leaving the league before the trade processes, mutual agreement by both parties, or any other rule violation. Flag suspected cases to the Commissioner immediately.

10. Tiebreakers & Competitive Integrity

11. League Customization

11.1 Relocation & Rebranding

GMs may request a team relocation or name change after managing a team for three full seasons. New locations should be in North America (Canada, Mexico, the U.S., or similar) and fit the division's geography. Minor league team relocations and renames can be requested at any time. Approved changes are announced in Slack, and a relocating team can reroll its park factors.

11.2 Nicknames

Each GM may assign one nickname per season to a player in their organization. You can't rename a player another GM has already nicknamed, and GM-created nicknames override auto-generated ones.

12. Violations & Inactivity

12.1 Missed Exports

Occasional missed exports are fine. Four or more consecutive misses disrupt team performance and league integrity, and trigger a commissioner-led AI reorganization if the team structure is significantly impacted. Notify a commissioner of any expected absence to avoid unintended team management.

12.2 Sim Violations

A sim violation halts the sim until the Commissioner takes corrective action on the violating GM's behalf. Common cases:

12.3 Replacing an Inactive GM

If a GM misses four consecutive exports without notice, the Commissioner will reach out on Slack and expects a response within 24–48 hours. No reply is treated as "ghosting" and prompts a replacement.

13. New Members

14. Hall of Fame

Players stay on the HOF ballot for up to 10 years post-retirement as long as they get at least one vote annually. A player can't appear on the ballot if they had major league activity the prior season. Election requires 75% of the vote, and each GM gets up to ten votes. HOF voting begins at the start of the off-season and closes once the league sims to free agency.

15. Proposing Rule Changes

Any GM can propose a rule change or addition. Submit proposals to the Commissioner or in #proposals with clear, thorough reasoning. New rules typically take effect in the off-season, unless they can be applied immediately without disrupting the current season. Voting on proposals is a league duty.
