Every row is a share of the same 177 batters faced, so the lengths are directly comparable. Other outs are derived — batters faced less hits, walks and strikeouts — and a batter who reached on an error is counted among them. The mark on each row is what a regular does — 256 pitchers with at least 200 batters faced this season, pooled.

ERA and WHIP share one scale but measure different things — compare each line with itself across seasons; the vertical gap between the two is not a performance margin.

Raw season totals, not per-game rates. Playing time and season length affect every bar, so a shorter bar does not necessarily mean worse rate performance.

The selected season does not carry enough of the hitting line to break it into outcomes.

All four rate stats share one scale. OPS is OBP plus SLG, so it naturally sits above its components; the exact values are in the season table.
