Reliever Roundup & Bullpen Bonanza — Week 4 Individual Rankings

We are at the beginning of Week 4 of the 2024 season. We’ve played enough games to publish our first reliever rankings of 2024. Here are the top ten individual relievers in each league. But these rankings take it to a different level than the other reliever rankings you’ve seen. We will separate our rankings by closers, setup men, and middle relievers. (We’re not going to worry about ranking long relievers but will lump them in with the middle relievers.)

Rankings are split into the following categories. These categories encompass what a relief pitcher’s jobs are and are weighted according to importance. We don’t want to get bogged down, so we’ll keep it brief. (Author’s Note: For full details, including the full leaderboards, leave a comment and I’ll be glad to get back to you.)

Setup Men and Closers

Clutch (45% of score) — How well they perform in late innings either while the game is tied or while holding a narrow lead.

Run Prevention (35%) — How well they keep runs off the board, including inherited runners.

Baserunner Prevention (13%) — Who has the lowest WHIP and lowest home run percentage (HR%). WHIP is 85% of the Baserunner Prevention score, and HR% is 15%.

Command (7%) — Who has the best strikeout percentage minus walk percentage (K–BB%).

Middle Relievers

Run Prevention (60%), Baserunner Prevention (26%), Command (14%)

Totaling Up the Scores

The total score in each category is based on the league average. Zero points equals the league average. Positive scores are better than league average; negative scores are worse. The farther their score is from zero — either positive or negative — the farther they are from the league average.

In addition, a player must have at least six relief appearances to qualify for these rankings.

(Note: Due to weighting each score, adding the categories together won’t equal the total score.)

Full Score Explanation

For clutch, we will use both the Goose Egg total (33%) and the ratio of Goose Eggs to Broken Eggs (67%) due to the major flaws in Saves and Holds. Full details about Goose Eggs are here. Otherwise, here’s the elevator speech.

A Goose Egg is like a save, except more restrictive. Here are the main points…

  • It’s done inning by inning, starting in the seventh.
  • Maximum of a two-run lead, not three, but it also includes tie games. Like the save, exceptions are made if the tying run is on base or at bat. (Not on deck, however.)
  • Run Breakdown:
    • No run of any kind — earned, unearned, or inherited — scores, it’s a goose egg (GE).
    • Earned run charged to the pitcher, it’s a broken egg (BE).
    • Any other run scores, it’s neither.
    • Earned run scores in an inning where he closes out the victory, it’s also neither.
    • Starts the inning and gives up no runs, but doesn’t finish the inning, it’s also neither.
  • He must finish the inning while recording the following number of outs:
    • No one on when he starts the inning — all three;
    • One on — at least two;
    • Two or three on — at least one.
  • Any time it’s “neither,” it’s called a “Meh,” as in “nothing special.” They’re like a stalemate in chess and count as nothing, so we really don’t talk about them.
  • Most important is the ratio of GE to BE (GE/BE). The historical average, dating to 1921, is 3.0, or 3-to-1.

For run prevention, we will use a mixture of the Scoreless Outing Percentage (Earned Runs only), Inherited Runners Scored Percentage (IS%), and ERA-minus. ScOtg% is 75% of the score, IS% is 15%, and ERA-minus is 10%.
