Last season, Rithmm's MLB product was in beta. Limited prop options. No premium model building. If you used it then, you got a glimpse of what the models could do — but not the full picture.
This season is different. Rithmm's 2026 MLB release is a full build: complete game line coverage, 14 prop types, and a premium model builder that lets analytical users build custom models from a library of hundreds of statistics.
Here's exactly what's covered.
Every core game line is now fully covered with Rithmm model predictions:
The models run the same opponent-adjusted, park-adjusted predictive process on game lines as they do on props — not just surface stats, but situation-specific probability outputs built from years of historical MLB data.
Last season's limited prop selection is gone. Here's the full prop suite available in 2026:
Every prop runs through the same opponent-adjusted modeling framework detailed in What Actually Goes Into an MLB Betting Model: strikeout tendency rates calibrated to opposing pitcher stuff, contact quality adjusted for game state, park factors applied to power props. The model sees the full matchup, not just season-long averages.
This is the piece that wasn't available last season and changes the product entirely for analytical users.
Inside the model builder, you can build your own custom factors by selecting 1-5 statistics from a library of hundreds, organized across multiple categories:
Sabermetrics — advanced efficiency and value metrics built for analytical depth.
Hitting — at-bat splits, plate appearance rates, runners-in-scoring-position data, strikeout rates, and more. Examples: At Bats Per Plate Appearance, At Bats Per Strikeout, At Bats with Runners in Scoring Position Per At Bat and Per Game.
Fielding — a full suite of defensive metrics most betting tools don't touch. Examples: Assists Per Fielding Chance and Per Game, Outfield Assists, Putouts, Runners Caught Stealing, Passed Balls, Double Plays, Fielding Errors, Throwing Errors, Interference Errors — all available per fielding chance and per game.
Run Environment — metrics that shape the context of how runs are produced and prevented.
You name your factor, select the stats that make up your formula, and build it directly inside the app. If you've been running your own spreadsheets or custom models outside a betting tool, this is the bridge — the same statistical depth, inside a system that's already running predictive outputs on tonight's slate.
Daily games. Months of baseball ahead. The model is running opponent-adjusted outputs on tonight's slate right now.
If you tried the beta and moved on, this is a different product. If you haven't used Rithmm for MLB yet, this is the version it was built toward.
