OBP + SLGUnlike traditional Batting Average which treats all hits equally, wOBA weighs Home Runs (2.10) over 3x higher than Singles (0.89) and values walks (0.69). With a 208 wRC+, this hitter generates 108% more offensive runs per plate appearance than the average MLB player.

True Talent FIP10.45
Per 9 InningsBecause this pitcher's FIP (2.42) is lower than their ERA (2.72), the pitcher suffered from poor defensive fielding or unlucky batted-ball sequencing. Their true pitching talent is even better than their ERA suggests!

True Talent Record-3 Wins
UnderperformingWith a +200 run differential (850 scored vs 650 allowed), the team's true talent expectation is 101 wins. With only 98 actual wins, the team was slightly unlucky in 1-run games and is poised for positive win regression.

The Moneyball Evolution: How wRC+ and FIP Replaced Batting Average and ERA
An analytical breakdown of linear weights, defensive fielding noise, and why modern front offices value on-base percentage and strikeout-to-walk ratios.
The Linear Weights Revolution
Traditional stats like Batting Average treat an accidental bloop single identical to a 450-foot home run. Sabermetrics uses play-by-play historical data across 100,000+ games to calculate the precise run value of every event: a Walk is worth +0.69 runs, a Double is worth +1.27 runs, and a Home Run is worth +2.10 runs.
Frequently Asked Questions (Baseball Sabermetrics & wRC+)
How does ballpark adjustment work in wRC+?
wRC+ accounts for the environment where games are played. Hitting 30 home runs at hitter-friendly Coors Field in Colorado yields a lower wRC+ than hitting 30 home runs at pitcher-friendly Oracle Park in San Francisco, allowing fair comparisons across all 30 MLB stadiums.
What are the "Three True Outcomes" in modern baseball?
The Three True Outcomes are Home Runs, Strikeouts, and Walks—events where the defensive fielders have zero influence on the play. FIP is calculated exclusively using these three metrics to eliminate defensive fielding bias.
