dispatch Routes a baseball analytics request to the right 2 to 3 skills in this pack. Fastballapi tool Default data source for the FastballAPI skills. Game lookup Finds MLB and college baseball games by date, date range, team or season, and pulls one game in full: line score, box score, starters, bullpen usage, each book's line and the win-probability range. Game preview Builds a pre-game report for one MLB or college baseball matchup: records, run differential, Elo, recent form, injuries, the median and per-book lines, and what the market implies. Odds analysis Converts baseball betting odds between formats and removes the bookmaker margin to get true implied probabilities for moneylines, run lines, totals and player props. Odds explorer Compares MLB and college baseball sportsbook lines across books: moneyline, run line and total, best price, opening vs closing, vig, and pre-game line movement. Pitch mix analysis Analyzes an MLB pitcher's arsenal: pitch types, usage, average and top velocity, whiff rate per swing, ball rate, usage by count, velocity by inning and platoon splits, from FastballAPI pitch-by-pitch data. Player scouting Scouts MLB and college baseball players: finds a player id, pulls season-by-season batting (AVG, OBP, SLG, OPS, K%, BB%, RE24) and pitching (ERA, WHIP, K/9, BB/9) lines, game logs, season leaders and injury status, and compares players fairly. Prop modeling Builds player prop projections for MLB: pitcher strikeouts and outs, batter hits, total bases, home runs and RBI. Pythagorean record Computes Pythagorean and Pythagenpat expected records from runs scored and allowed, measures how far a team's actual record is from it (luck), and projects regression for MLB and college baseball. Run value analysis Measures what happened in baseball in runs and win probability: RE24 run value per plate appearance, base-out state, runners in scoring position splits, win probability added and leverage-style context for MLB and college baseball. Spray chart analysis Reads where an MLB batter or team hits the ball: balls in play by trajectory (ground ball, line drive, fly ball, pop-up) and by field (left, center, right), hit rates, home runs per fly ball, pull and opposite-field tendencies, and ball-by-ball x/y points for drawing a spray chart. Team analysis Analyzes MLB and college baseball teams: standings, home and away splits, runs scored and allowed, team batting and run prevention, Elo power ratings and strength of schedule. Walk forward validation Evaluates baseball prediction models honestly with time-ordered walk-forward splits: leakage-safe rolling features, expanding vs sliding windows, baselines (home field, Elo, closing line), log loss, Brier score and calibration checks.
