Data notes
The comparison sets a rolling 30-day rate against a season-to-date rate built on a larger sample, so the gap is a hot-streak signal, not a rest-of-season forecast. The window requires at least 30 balls in play, so small samples are filtered out, and hitters only: the rolling feed is built from balls in play, so pitchers are not ranked. See the rolling leaderboard for the last 30 days for the full ranking and the card rankings hub for rating-based views.
