MLB Picks Today,
with the losses still attached.
Posterior publishes a daily MLB model board built from price, probability, and settlement discipline. This page reports the board exactly the way the product does: how many picks qualified today, when the board locked, and what the season record looks like with every loss still in the count.

02 / How it works
Step 01
Price the baseball event
The model estimates the outcome probability from player talent, recent form, matchup shape, and game context. Props use market-specific model heads; game markets use team-level simulations. The output is a probability, not a narrative.
Step 02
Compare against the market
Book prices are converted into a no-vig consensus baseline so the model is measured against a fair number. A pick needs a real gap between model probability and market probability at a price that was actually available — not a theoretical midpoint.
Step 03
Apply the quality gates
Quote freshness, book allowlists, lineup and starter confirmation, market depth, and edge size all act as gates. The lock archive then freezes every decision with its quote and timestamp, so the board cannot be quietly rewritten later.
Step 04
Resolve in public
Official results grade each row won, lost, or voided. Settled rows join the public record after the release delay, the season record updates, and the same figures you see on this page refresh — win or lose.

Public proof
Good picks are allowed to be quiet.
No forced slate coverage. If a market fails the edge, price, or quality gates, it stays out of the public pick set.
03 / Questions
Are these free MLB picks?
The board count, lock time, season record, and the delayed resolved ledger are free and public — that is most of what this page reports. The live actionable entries themselves (subjects, lines, prices) are subscriber-only inside Posterior Pro, because publishing them would move the very prices the model measures. One free pick is pinned publicly each day on the homepage when the board supports it.
Do you publish picks for every game?
No, and the board count above proves it. A game only appears if the model found a qualified edge at a playable price in one of its markets. Slates with thin pricing or unconfirmed lineups routinely produce games with no pick, and some days the whole board publishes with zero qualified opportunities. Coverage is never the goal; a defensible price is.
Where can I check the results?
The delayed public ledger at https://posterior.pro/data lists resolved rows with model probability, market probability, grade, price, and outcome, downloadable as CSV. Season-level win rate, Brier score, and ROI figures are published at https://posterior.pro/mlb/accuracy and through the public /api/mlb/accuracy endpoint — the same numbers this page relays.
When does the board lock each day?
The lock runs ahead of the day's first pitches and the exact time varies with the slate, which is why this page shows today's actual lock timestamp when the board is published. Once locked, decisions are immutable: a late scratch becomes a void, not a deleted pick, and the archive keeps the original quote and reasoning.
What does it mean when a pick is 'qualified'?
Qualified means the row passed every gate at lock time: a fresh quote from an allowlisted book, a model edge over the no-vig consensus large enough to grade, confirmed lineup or starter context where the market requires it, and no runtime quarantine on the market. Anything less stays at WAIT or PASS and never becomes a public-facing pick.
Posterior is baseball data, not a sportsbook. The public receipt lives at /data, the methodology lives at /methodology, and today's board starts at /today.
