oWar — Offensive Wins Above ReplacementMeasures how many wins a hitter contributes above a hypothetical replacement-level player. Calculated from wRAA (Weighted Runs Above Average) + a positional adjustment + a park/SOS adjustment, then scaled to wins using the D3 run environment (~8.5 runs per win). A score of 0 = replacement level; 1.0 = one win above replacement for the season.oWar = (wRAA + Pos_Adj + Park_Adj) / RPW × SOS_MultiplierpWar — Pitching Wins Above ReplacementMeasures how many wins a pitcher contributes above replacement level. Based on FIP (Fielding Independent Pitching) to remove defense, converted to runs prevented above replacement, then scaled to wins. Adjusted upward for pitchers who face stronger opponents (higher SOS). Starters and relievers are compared against position-appropriate baselines.pWar = (FIP_Replacement − FIP) × (IP / 9) / RPW × SOS_MultiplierwOBA — Weighted On-Base AverageA single-number offensive rate stat that weights each way of reaching base by its actual run value. More accurate than OBP or OPS because it treats each event proportionally. D3-calibrated linear weights: BB = 0.69, HBP = 0.72, 1B = 0.88, 2B = 1.24, 3B = 1.56, HR = 2.00. League average wOBA in D3 is typically around .330–.345.wOBA = (0.69×BB + 0.72×HBP + 0.88×1B + 1.24×2B + 1.56×3B + 2.00×HR) / PAAdj wOBA / Adj OPS — Schedule-AdjustedwOBA and OPS adjusted for the strength of opponents faced. A player who posts a .400 wOBA against top-ranked opponents is more valuable than one who does it against weak competition. SOS-adjustment scales each stat relative to the average quality of opponents faced, using the NPI-based Strength of Schedule metric.FIP — Fielding Independent PitchingAn ERA estimator that only uses outcomes the pitcher directly controls: strikeouts, walks, hit-by-pitches, and home runs. Removes the effect of defense and luck on balls in play. Scaled to the same run environment as ERA using a D3-calibrated FIP constant (~4.2). Pitchers who consistently outperform their FIP may have strong defense or be getting lucky.
