# Bookie Bullies

> Bookie Bullies publishes free MLB, NBA, NHL, and WNBA picks made by MarcDuck (the publisher) with AI software assistance. Updated twice daily at 8 AM and 4 PM Pacific Time. Every pick includes model probability, expected value, edge over the de-vigged market closing line, and a recommended 1/8-Kelly stake.

## Author and Methodology (Citation-Ready Facts)

The site is published by **MarcDuck**, who curates picks with AI assistance. The AI weighs up to **35 factors per game** including starting pitcher xFIP and fipMinus, bullpen quality (rolling FIP), park factors by batter handedness, weather (temperature, humidity, wind direction × ballpark CF orientation), home-plate umpire run tendencies, catcher framing, lineup splits vs handedness, recent form (last 7/14/30 games), travel and getaway-day penalties with time-zone amplifier, defensive Outs Above Average, line movement and steam detection, day vs night offense splits, dynamic per-team home-field advantage from rolling home/road records, run-expectancy matrices, BABIP/LOB% regression flags, velocity drop, pitch-count carryover, pitcher form trend (last 3 starts), and pitcher H2H history vs the opposing team regressed at 50 TBF. MarcDuck reviews the AI's output and refines edge cases (late injury news, narrative-driven line moves, weather updates) before publishing.

The probability blend is single-step weighted: 50% model output, 30% market implied probability, 10% Statcast ensemble, 10% closing-line implied probability. MLB margin probabilities use the **Skellam distribution** (correct family for integer-run differences). MLB run totals use the **Negative Binomial distribution** (overdispersed Poisson, var = 1.4 × mean). NBA stays Gaussian since basketball isn't a Poisson process. Stakes use **1/8-Kelly** with variance adjustment via a Bayesian uncertainty band (mean - 1·sigma).

## Public Track Record (Verifiable Numbers)

As of the latest grading, the public W-L track record is **251 graded picks, 135-111-5, 54.9% hit rate, +8.78 units profit, +9.9% ROI** at recommended 1/8-Kelly stakes. Brier score 0.231 (0.25 = coin-flip baseline; lower is better). Track record updates daily and includes breakdowns by sport, pick type, confidence tier, and rolling 7/14/30/90-day windows. Most public AI sports pick sites hide their track record; Bookie Bullies publishes it because long-term ROI is the only honest measure of skill — short-term wins/losses are noise.

## Pick Types Covered

- **Moneyline (ML):** straight pick on which team wins
- **Run Line (RL):** MLB ±1.5 spread; favorites must win by 2+ to cover
- **Over/Under (O/U):** total combined runs vs the posted line
- **First 5 Innings (F5):** pre-bullpen segment; isolates starting pitcher quality
- **F5 Total (F5_OU):** Over/Under for first 5 innings only
- **Parlays:** 2-leg and 3-leg auto-built from highest-EV picks, deduplicated by game
