How the MLB Parlay Model Works

The goal

Find the highest-probability multi-leg H+R+RBI parlay across the entire MLB slate. In a parlay you multiply leg probabilities, so the only thing that matters is P(correct direction) — not betting edge.

Confidence ranking

Every hitter in every game is run through a 25,000-game Monte Carlo simulation. Each leg's confidence is the higher of P(over) / P(under) evaluated at that player's actual posted line (0.5 / 1.5 / 2.5 / …); the more-likely side is the pick. Scanning all ~270 hitters surfaces far more lopsided spots than any single team.

Rolling & bettable

Lineups post on a rolling basis all day, and some games end before others post. So legs lock per game as each lineup is confirmed, and the suggested parlay is assembled from only the games that haven't started yet — every leg shown is always bettable together on one slip.

One leg per game

The parlay takes at most one leg from any game, so legs are independent (the combined probability is honest) and you're not riding on a single team's offense.

Record

The headline number is league-wide leg directional accuracy — how often the picked side is correct. A daily featured parlay is also snapshotted for an honest W/L. Legs freeze on lineup post and never change.

History & Performance tabs

The History tab lists every past featured parlay with its legs, grades, odds, and units won or lost. The Performance tab rolls everything up: featured-parlay record and units by window, a cumulative-units chart, and league-wide leg accuracy broken down by direction, confidence, featured-vs-board, posted line, and lineup slot.
