Timeless Baseball League
TBL: Timeless Baseball League — Yesterday's Legends. Tomorrow's Box Score.
Draft Pedro's 2000, Bonds' 2001 and Rickey's best legs onto one club. Multiple leagues run at once, each with its own owners, and the sim plays a game every night while you sleep.
2 · Claim your club
Every owner signs in, joins with the code, names their club and marks ready. The draft unlocks when all seats are filled.
3 · Snake draft legends
Pick real single-season cards — 2000-present by default, back to 1985 if the commissioner opens the vault. Miss your turn and autodraft covers you.
4 · One game a night
At 3:00 AM Eastern every league plays the next game of the week. Watch the category race move each morning; the week is scored when the series ends.

- What is the Timeless Baseball League (TBL)?
- A head-to-head fantasy baseball game played with real single-season cards from baseball history. You draft seasons like Pedro Martinez 2000 or Barry Bonds 2001 and they perform the way they actually did.
- How are games decided?
- Every plate appearance is resolved with log5 odds-ratio blending of the batter's rates, the pitcher's rates and the era-adjusted league average, then run through a 24 base-out state model. Results are seeded, so a league's games are consistent every time they are viewed.
- When do games play?
- One game of the week is simulated for every active league at 3:00 AM Eastern each night. Weeks are scored on categories once the series finishes, so the race moves a little every morning.
- How many people can play?
- Up to 12 owners per league, and any number of leagues can run at the same time. The commissioner shares a join code; unclaimed seats are run by the computer.
- Which seasons are available?
- The top 200 players from every season since 1985. Commissioners choose the card era — 2000-present by default, or open the vault back to 1990 or 1985 for a deeper pool.
- Is it free?
- Yes. Timeless Baseball League is a free hobby project with no entry fees, prizes or wagering.
