Goose Egg Relief Pitching Metric

This dataset introduces the 'Goose Egg,' a modern statistic proposed by FiveThirtyEight to better evaluate relief pitcher performance than the traditional save.
Based on game situations and outcomes, the Goose Egg framework tracks effective relief appearances, blown opportunities ('Broken Eggs'), and neutral outcomes ('Mehs').
The dataset includes season-level stats for MLB pitchers, with derived metrics like Goose Wins Above Replacement (gWAR), adjusted for park effects and league averages.
