Eephus

A high, slow rainbow at a crawl. Its only weapon is throwing off a hitter's timing.

Open this like an archive drawer: grip first, source attached, shape in words, no invented spin or movement numbers. The file exists so the hold can keep moving forward.

Shape read

Rides

The shape is up, then down — a towering rainbow, not a sideways dart. The ball climbs high above head height between mound and plate, hangs there, then falls into the strike zone on a steep descending angle. The arc and the hang time are the whole pitch; nothing about it is late or sudden.

ShapeReputable analysis

Almost any grip — usually an ordinary fastball or curve hold — thrown with drastically reduced arm speed on a high, exaggerated overhand lob. The grip barely matters: the pitch is defined by its trajectory and its speed, not by how the ball is held.

UnverifiedMLB.com Statcast Glossary, Eephus (EP)

No source supports one canonical eephus grip. The cited references describe an ordinary fastball or curve hold lobbed on a high arc — the pitch lives in the trajectory, not in the fingers.

The grip stays undrawn on purpose: any fingers placed here would be invented geometry, and this atlas does not invent. Read the release cue instead.

Read this insteadThrow it on a high, exaggerated overhand arc with drastically reduced arm speed, aiming to peak well above the batter and drop in.

Grip geometry is schematic and barely matters here; the eephus is defined by arc and timing, not grip.

Paraphrased. MLB.com describes a pitch thrown very high in the air, resembling a slow-pitch softball trajectory; the overhand-lob delivery is the craft consensus.

The complete grip notes
  1. Take any ordinary grip — a fastball or curve hold is fine.
  2. Throw it overhand on an exaggerated high arc, with drastically reduced arm speed.
  3. Aim for the ball to peak well above the hitter and fall into the strike zone.
  4. Pick your spot: it works once in a while, when a hitter is sitting dead-red, and gets crushed if they are ready.

Lob it on a high arc with way less arm speed than a fastball. Aim to peak above the batter and drop it into the top of the zone.

MLB.com calls it, by design, the easiest pitch in baseball to hit — no unexpected movement, nothing on it. Its only weapon is the disruption: a hitter timed for heat has to wait on a pitch that floats in at a crawl.

Reputable analysisMLB.com Statcast Glossary, Eephus (EP)

Paraphrased. MLB.com: "it is the easiest pitch to hit in baseball" — the timing scramble is the point.

Oddly, it is not a no-spin pitch — it carries ordinary backspin, a touch more than a typical fastball. But thrown this slow, that spin barely matters. Gravity, not the spin, owns the flight.

Paraphrased from James LeDoux's Statcast study of tagged eephus pitches. Described as shape and feel, not a measured figure.

Rip Sewell invented it during World War II — the story ties it to a 1941 hunting accident — and the name comes from a teammate's line that "eephus ain't nothing, and that's a nothing pitch."

Paraphrased. The Sewell origin and the Maurice Van Robays "nothing pitch" naming are documented in The Hardball Times.

Release Room

Translate the hold into a release

Grip shape only matters if the release makes sense. Read pressure, thumb support, and ball depth before you read the pitch shape.

01

Hold

Held loosely like a fastball or curve — almost any grip works.

02

Pressure

Thumb underneath for control; the grip is ordinary because the arc, not the spin, is the pitch.

03

Leave

Throw it on a high, exaggerated overhand arc with drastically reduced arm speed, aiming to peak well above the batter and drop in.

It is lobbed in at a small fraction of fastball pace on a towering rainbow that climbs well above head height before dropping into the zone on a steep angle. It is a once-a-game weapon: it works on timing, not stuff, and a hitter who is ready for it can crush it.

Reputable analysisThe Hardball Times, Rip Sewell, the Eephus, and the All-Star Game

Paraphrased. The towering arc and crawling pace are described as shape and feel, per The Hardball Times.

Movement

It carries normal backspin, but thrown this slow, gravity shapes the giant arc the plot cannot draw. Spin barely figures in.

The read is shape, not a gauge. The spin words explain why it moves that way, and every prose claim still carries its source.

Spin words

A near-12:00 backspin orientation with little side tilt, so there is essentially no horizontal run and no platoon side. Inferred from the backspin it carries — and at this crawl the orientation hardly changes the flight anyway.

Reputable analysisMLB.com Statcast Glossary, Eephus (EP)

Craft read

An eephus is a giant, slow rainbow, lobbed in at a fraction of fastball pace. It does not dart or dive. It just hangs in the air much longer than a hitter expects, then drops into the zone. A batter geared up for heat has to wait, and waiting is the hardest thing to do at the plate.

The one teaching sentence

Every other pitch in the atlas uses spin to move or to resist gravity. The eephus does neither — it surrenders to gravity. Lobbed in at a fraction of fastball pace on a high arc, it hangs in the air far longer than anything a hitter has timed, and the hardest thing in hitting is recalibrating to a pitch that floats in slow and late.

Master Files

The master files

Two eephus throwers, eighty years apart: the man who invented it, and the modern artist who still dares it. The visual is our own seam schematic. What sets each version apart lives in the read, not a gauge.

Rip Sewell

The originator. His "folly floater," born in wartime, became a genuine weapon — until the one man who solved it did so on the biggest stage.

The towering wartime original — a sky-high rainbow that hitters of the era simply could not handle, until Ted Williams stepped forward and homered off it in the 1946 All-Star Game, the only home run ever hit off the pitch.

Zack Greinke

The modern keeper of the flame: a cerebral pitcher who will drop an eephus into the zone when the moment calls for it — even when he did not quite plan to.

The thinking man's version — a crawling lob dropped in for a called strike, slower than anything the modern game expects, deployed with a chess player's timing rather than as a novelty.

Another offspeed in the collection

Set it beside the circle change.

The thumb and index finger form an OK circle against the inner side of the ball while the other three fingers lay across the top. The ball rests deeper in the hand, which deadens the exit, and the off-center grip tilts the axis toward the arm for fade.

Tier 03 / Field Notes

Field notes from the bullpen.

Every pitcher fiddles. A thumb creeps lower, a seam catches more leather, a cue from a coach suddenly makes the pitch move. Pitch Atlas files those experiments as specimens with context, so the small discoveries stop disappearing into group chats and comment sections.

How notes rank

Evidence and context, never who shouts loudest.

There is no single correct way to throw a pitch, but there are better and worse claims. A funny line should never outrank a tested grip. So notes do not rise on raw votes. They rise on weighted signals - provenance and adoption first.

  • 35%
    Provenance

    Source tier and evidence. A coach-observed note with a link outranks an unverified hunch with none.

    Adoption

  • 20%
    Usefulness

    Marked useful, measured against views so a small loud crowd cannot stuff the rank.

Keeping the bullpen honest

Field Notes are live for grip and technique only. No medical, injury, workload, or youth-training prescriptions. Every note carries a source and confidence label, and contributors can report problems. No abuse, no personal attacks, no off-topic spam, nothing aimed at minors. New field notes stay private until review. See a problem with a public note? Use Report on it; a note flagged by enough people is hidden automatically until it is checked.

Every community variant carries the same source and confidence labels as the records above. Nothing appears here unsourced, and no count is shown until it is real.
