Derived = season-usage role from pitcher-profiles.json. Card tag = what tonight's card thinks. When they disagree, the sim picker may target wrong arms in save windows. Mean IP/app distinguishes 1-IP relievers from bulk arms.

glossary

Pitcher metrics

  • xERA (Savant): Statcast's expected ERA, derived from xwOBA. Strips defense/luck — what the pitcher's contact quality says he should have given up.
  • xwOBA (Savant): Expected wOBA. Treats each batted ball by exit velo + launch angle (independent of where defenders stood). Lower = better for pitcher.
  • wOBA-xwOBA (Savant): Actual minus expected. Negative = the pitcher has been UNLUCKY (better than results show). Positive = LUCKY (worse than results show).
  • Outs/TB: Outs recorded ÷ total bases allowed. Custom efficiency metric. Higher = more efficient. Starter range typically 1.5–3.0.
  • FIP: Defense-independent ERA estimator using only K/BB/HBP/HR. Removes BABIP luck. Same scale as ERA.
  • kwERA: Strikeout-and-walk-only ERA estimator. 5.40 − 12·(K−BB)/PA. Strips contact entirely. K-BB% is the most stable pitcher skill.
  • K% / BB%: Strikeouts / walks as a share of total batters faced.
  • IP (25+26 combined): Total innings across the prior + current season — defines the IP-weight on combined stats.
  • Arsenal RV/100 (Savant): Run Value per 100 pitches, weighted across the pitcher's mix. POSITIVE = stuff playing well for the pitcher. Substitute for FanGraphs Stuff+.

Batter metrics

  • AVG/OBP/SLG: Standard slash line, current season.
  • vs L/RHP AVG/OBP/SLG (PA): Same line, but only against pitchers of the hand the batter is facing tonight. PA = sample size — small samples (<50 PA) are noisy.
  • xwOBA / xBA / xSLG (Savant): Statcast expected stats for the batter, based on contact quality.
  • xwOBA(25) (Savant): Last year's xwOBA. Useful when current-year sample is thin.
  • FRV (Savant): Fielding Run Value. Range + arm + framing + blocking + DP turns. Cumulative — early-season values are small.
  • Match xwOBA: Projected weighted xwOBA against this specific pitcher's pitch mix. Per pitch (with usage %), look up batter's xwOBA vs that pitch type, weighted average.
  • Cov%: Share of opposing pitcher's pitch usage where we have direct batter-vs-pitch data. Lower coverage = less reliable matchup score.

Lineup status

  • 🟢 CONFIRMED: Posted by the team via MLB Stats API. This is the actual lineup playing.
  • 🟡 EXPECTED: Projected from the team's last 21 days of starts vs the same handedness, with current IL filtered out. Refreshes ~T-90 min before first pitch.

Data sources

  • MLB Stats API (statsapi.mlb.com): schedule, lineups, raw counting stats (K/BB/HR/IP/AVG/etc.), L/R splits.
  • Baseball Savant (Statcast): xERA/xwOBA, pitch arsenal, Fielding Run Value, expected stats. Descriptive only — no projection system.
  • Baseball Prospectus: DRC+ + PECOTA when authed.
  • Open-Meteo: Weather forecast rotated to the park.
