Sharps don't lose
to other sharps.
They lose to better tools.

The MLB prop market has gotten harder. Sportsbooks model the same Statcast data you do. Public-facing tools serve precomputed projections you can't argue with — black-box outputs with no sample sizes, no priors, no methodology.

When the batter's facing his fifth at-bat against a pitcher across his career, every tool on the market shrugs. BallBet runs the comp sample. Runs the sim. Shows you the math.

This isn't a picks service. It's a simulation platform built for bettors who think in distributions.

// WHAT YOU GET

Built for bettors who
think in distributions.

Three pillars that separate BallBet from a picks service.

01 / CUSTOM INPUTS

Your parameters, not league averages.

Set park, weather, lineup, recent form, platoon splits, BvP weighting. The model runs on your priors. Every other tool serves precomputed projections you can't touch.

02 / REAL BvP DATA

Batter-vs-pitcher, integrated and expanded.

Direct BvP history baked into the simulation. When the sample's small, the Comp Lab finds statistically similar batters and expands the sample 5–10×. Sample size shown on every output.

03 / CLOSED LOOP

Sim → bet → calibrate.

Every tracked play ties back to the original model output. Watch your calibration improve over time. The only feedback loop that matters — and the one no competitor builds.

// THE PRODUCT

Three pages that
change how you bet.

Built around the workflow sharps actually use: model the matchup, find the edge, track the result.

01 · CUSTOM SIMULATOR

Adjust the priors.
Re-run the sim.

Every input the model uses — pitch mix weight, park factor, lineup position, BvP sample weight, recent-form decay, fatigue — exposed as a slider. Change one. Watch the distribution shift.

25,000 trials per run. Every output shows the full probability distribution, modeled edge vs. market line, Kelly-sized stake at your bankroll, and sample size on every input.

  • Sliders for park, weather, lineup, fatigue, BvP weighting
  • Compare-to-default toggle shows your delta vs. model defaults
  • Save your priors as presets (Edge tier)

02 · PITCH MIX MATCHUP

Query the whole slate
by pitch arsenal.

Other tools show one batter's pitch mix vs one pitcher. We let you query across every game on the board: “show me batters facing slider-heavy pitchers where the batter's xSLG vs sliders is above .500.”

Save your favorite queries. Get them auto-flagged on tonight's slate. Pro users save 10. Edge users save unlimited.

  • SQL-like query builder across all 30 active hitters per slate
  • Filter by pitch usage %, velocity, batter xSLG/whiff%, sample size
  • Direct sim integration — one click runs the matchup

03 · EDGE BOARD + TRACKER

Every play ties back
to the sim that called it.

The Edge Board surfaces the model's top simulated edges across the slate — not as picks, as model output. Every row shows methodology: sample size, modeled probability, fair line, and the sim parameters used.

Bet from any row, and the tracker auto-links the play to the sim. Watch your calibration improve over time. Or your model lose its edge in a slump — either way, you see it.

  • Calibration dashboard shows model accuracy by edge band
  • CLV computed automatically against the closing line
  • Public calibration view — sharps can audit our hit rate (Free tier)

// THE WORKFLOW

Three steps. Every night.

The workflow is built around how sharps actually bet — not how content sites pretend they do.

01

Run the sim.

Pull up tonight's slate. Click any matchup. Adjust the priors that matter — park, weather, lineup, BvP weight. 25,000 Monte Carlo trials run in under 2 seconds.

02

Find the edge.

The sim outputs a full probability distribution. Compare modeled fair line to the sportsbook line. If there's a real edge, it shows up with sample size and confidence band. If not, move on.

03

Track the result.

Bet the edge. The tracker auto-links your play to the sim. Over weeks, watch your calibration improve. CLV computed against the closing line — no manual math.

// THE DIFFERENCE

Built differently
from the alternatives.

Other MLB tools sell you a model's outputs. We sell you the model.

WHAT MOST TOOLS SHOW YOU
WHAT BALLBET SHOWS YOU
PROJECTIONS
Pre-computed numbers. No parameters to adjust. Trust the model or don't.
SIMULATIONS
Every input exposed as a slider. Tune the priors, re-run the 25k-trial sim, watch the distribution shift in real time.
PITCH MIX
One batter's pitch breakdown vs one pitcher. View it player by player.
QUERYABLE PITCH MIX
Scan the whole slate. “Slider-heavy pitchers vs batters with .500+ xSLG vs sliders, min n=50.” 12 results in 200ms.
SMALL BvP SAMPLES
Show you a 4-PA BvP history. Let you draw your own conclusions from sample-of-nothing.
COMP-EXPANDED BvP
When raw BvP n<20, the Comp Lab finds statistically similar batters. Expand the sample 5–10× with transparent comp scoring.
MODEL UPDATES
Overnight. Lineups, weather, and last-minute scratches don't refresh the projections until tomorrow.
LIVE RE-SIMULATION
Re-run the sim mid-game. Starter gets pulled in the 4th? Wind shifts at first pitch? Re-sim with current state. (Edge tier)
BET TRACKING
Generic tracker. Logs your bets. Has no idea what model recommended them.
CLOSED-LOOP TRACKING
Every play links back to the sim that called it. Calibration dashboard shows your model's hit rate by edge band over time. CLV automatic.
METHODOLOGY
Black box. "Trust the model." Sample sizes hidden. Priors undocumented.
FULL TRANSPARENCY
Sample size on every output. Priors visible. Methodology page details the whole sim pipeline. Calibration is public — audit our hit rate yourself.

// COMMON QUESTIONS

Short answers
to sharp questions.

How is the model validated?

Every parameter and feature weight is backtested against held-out historical seasons. The Calibration Dashboard is public — anyone can audit how the model's edge bands have actually performed across thousands of tracked plays. We don't ship anything that doesn't beat the baseline by validated thresholds.

Do you publish losses, not just wins?

Yes. The Calibration Dashboard shows hit rate by edge band — including the bands where we underperformed expectations. That transparency is the whole trust mechanism. Tools that hide losing streaks are tout services. We're not that.

What makes Pro worth $19 over BallParkPal's $10?

Two features they don't have: custom sim inputs (we let you set park, weather, BvP weights, fatigue — they show precomputed projections only) and the queryable Pitch Mix Matchup (we let you scan the whole slate by pitch-mix criteria — they show one player at a time). If those don't matter to how you bet, BallParkPal is a fine tool.

Why no daily pick service?

Because pick services have 30–50% monthly churn and tank brand integrity the first losing week. Our Edge Board surfaces the model's top simulated edges with full methodology — sample size, modeled probability, fair line. You decide what to bet. Sharps interpret that as a tool. Touts can't fake it.

Is this legal in my state?

BallBet.AI is an analytics platform — we don't take bets and don't process them. The tool itself is legal everywhere. Whether sports betting is legal in your state is a separate question, and one you should answer before using sportsbook features. 21+ only. Bet responsibly.
