MLB Statcast 4 Factors
MLB 14-factor model = KBO 10 (FIP / xFIP / wOBA / Bullpen FIP / Recent Form / WAR / H2H / Park Factor / Elo / Defense SFR) + Statcast 4.
Currently shown: 4 factor explanations + 30-team entry paths. Team-level Statcast measurements (xwOBA · Barrel% · Hard Hit% · Launch Angle) live data integration = separate datasource integration carry-over.
Statcast 4 Factor Explanations
1. Expected wOBA (xwOBA)
0.200 ~ 0.500Expected wOBA estimated from launch angle + exit velocity. Removes luck (defense/ballpark/weather) to measure true contact quality.
Why it matters: While wOBA measures actual outcomes, xwOBA eliminates result noise to reveal true hitting skill. Top weight among Statcast 4 in the 14-factor model.

2. Barrel %
0% ~ 25%Barrel = minimum launch angle + exit velocity threshold met = avg .500+ AVG / 1.500+ SLG expected. Percentage per plate appearance.
Why it matters: Hard contact frequency. Raw signal for home run + extra-base production capacity.

3. Hard Hit %
20% ~ 55%Share of batted balls at 95 mph+ exit velocity. Lower threshold than Barrel = larger sample, more stable signal.
Why it matters: 95+ mph exit velocity sharply increases hit probability. Primary input axis for xwOBA.

4. Launch Angle
-30° ~ +50°Average batted ball launch angle. 10–25° = line drives / 25–35° = fly ball sweet spot. Too high = pop-up, too low = groundball.
Why it matters: The angle axis of Barrel. Same exit velocity produces different outcomes based on angle.
