Runs / 100 compares the run value of this player's realized eligible batted-ball outcomes with what those batted balls were expected to produce, retrospectively — here, more favorable than expected. How Contact Luck works →
Contact Luck is a retrospective description of realized outcomes, not a measure of stable batting talent and not a projection of future performance. The 95% interval reflects sampling uncertainty in the estimate itself — it does not indicate whether the underlying effect is "real" or "significant," and overlapping zero does not mean the observation is unreliable or should be discounted.
