The mound version of the hitters list. No borrowed run values, no replacement level:
every pitcher is scored only against the actual league average and spread of their own
season, on five things straight off the back of a baseball card — ERA, WHIP, strikeout
rate, winning percentage, and saves. The list is shorter than the hitters' — a pitching
staff is a handful of arms next to eight everyday bats, and Cooperstown's own ratio runs
about two hitters to every pitcher.

This is a living ranking, not a set of plaques. It's rebuilt from scratch every year
on the latest data, so a pitcher climbs on when his case passes the 150th and a borderline
name drops off when someone else's rises past him. Active arms are in — no five-year wait.
This is the 2025 edition; the twenty just outside the cut are listed at the bottom.
What's a Stat Above Average? Each pitcher-season is compared only to that season's own
league average and spread — a 1913 season is judged against 1913, a 2024 season against
2024. The five stats are each converted to a z-score, then blended with the weights from
this site's SAA — 25% ERA, 25% WHIP, 20% strikeout rate, 20% winning
percentage, 10% saves — into one number for the season. (ERA and WHIP are flipped, so a
lower-than-league mark is a positive z.) Those season numbers are then summed across
every qualifying season, each scaled to a 200-inning workload, so a long steady career
and a short dominant one can both add up to a genuine case.
The five aren't weighted equally. Like the hitters list — which leans on batting
average and power — this one follows the SAA formula: ERA and WHIP carry half the score
between them because preventing runs and baserunners is the job. Strikeout rate is the one
bat-missing skill on every stat sheet. Winning percentage and saves round it out at the
lowest weights.
Winning percentage and saves both lean on the team around the pitcher — run support, the
bullpen behind him, whether his manager used him to close. They're in the score because
they're in the SAA formula, but they do the least work: where this list and Cooperstown
disagree, it's usually because a pitcher's ERA and WHIP say something his win total
doesn't. The HOF column marks pitchers already voted into Cooperstown.
Negro Leagues pitchers are in the pool and scored the same way — Satchel Paige,
Bullet Rogan, and Willie Foster all land inside the top 50. The NeL flag beside a
rank marks a pitcher whose score draws on Negro Leagues seasons — a 40-plus-inning season
in a Negro Major League, which is why Don Newcombe carries it. Unlike the hitters list, there's
no shortened-schedule carve-out yet, so an arm whose surviving record falls short of 1,000
innings (Smokey Joe Williams, Bill Foster) is left out for now.
