How to use this:
FIP (Fielding Independent Pitching) measures what a
pitcher's ERA should be based on strikeouts, walks, and home runs. xFIP
goes further by normalizing HR/FB rate to league average. When FIP is much higher than xFIP
(positive gap), the pitcher is giving up more home runs than expected. Use the dated view
to inspect what was knowable at that point, without leaking future results into older reports.
