How these trends are calculated
Each window is the player's last 3, 5, or 10 games actually played, drawn from ESPN box-score actuals. Games missed do not count, so "Last 10" always reflects ten real appearances rather than a calendar span.
ESPN fantasy points use standard pitching scoring: 1 per out recorded (3 per inning), 1 per strikeout, and 2 per win, minus 2 per earned run and 1 each for hits and walks allowed. Saves, holds, and losses are not persisted upstream and are excluded.
Numbers refresh on every deploy from the latest baked snapshot.
