Who really said it

Ninety percent of this game is half-mental

Not Yogi Berra — actually Jim Wohlford Jim Wohlford born 1951 · Major-league outfielder, 1972–1986
Disputed In copyright

The earliest citation in Barry Popik’s dated chronology is a 4 April 1974 column in the Maryville (MO) Daily Forum, which quotes Kansas City Royals outfielder Jim Wohlford: “Ninety per cent of this game is half mental.” Yogi Berra is not credited with the line in print until 28 January 1979, almost five years later, and Wikiquote files it under Disputed.

Disputed credit — copy with the correction

“Ninety percent of this game is half-mental” Jim Wohlford, Kansas City Royals outfielder, quoted in the Maryville (MO) Daily Forum, 4 April 1974. Usually credited to Yogi Berra, but the Berra credit does not appear in print until January 1979. Verified via Quotle.info · Verbatim: “Ninety per cent of this game is half mental.”

Provenance

The 1974 column that got there first

Spoken by
Jim Wohlford, Kansas City Royals outfielder
Article
“‘Needlee’ Wohlford May Have Last Laugh” by Steve Cameron
Published
Maryville (MO) Daily Forum, 4 April 1974, p. 9, cols. 1–2
First Berra credit
28 January 1979 — Dick Young’s column (New York Daily News), Aberdeen (SD) American News, p. 11

He’s the kind of guy who manages, quite innocently, to always say the kind of thing that will haunt him (“Ninety per cent of this game is half mental…”). Maryville (MO) Daily Forum · 4 April 1974

The 1974 printing spells it “per cent” as two words. Note also how the columnist frames it — parenthetically, as an example of the sort of thing Wohlford is already known for saying, rather than as a fresh remark being reported for the first time.

Barry Popik’s dated chronology of the line

How the line travelled

  • 4 April 1974 — the earliest citation in Barry Popik’s chronology ↗. Steve Cameron’s column in the Maryville (MO) Daily Forum quotes Royals outfielder Jim Wohlford: “Ninety per cent of this game is half mental.”
  • 19 July 1974 — three months later the same chronology records a second claimant: Pete Mollica’s column in the New Castle (PA) News has White Sox manager Chuck Tanner saying “Baseball is 90 percent mental” — the earliest documented printing of the “Baseball is…” phrasing that the popular Berra version grew out of.
  • April 1977 — the same sentence is credited to Phillies manager Danny Ozark ↗ in the Des Moines Register (19 April) and the St. Petersburg Times (26 April), three years after Wohlford.
  • 28 January 1979 — the first citation crediting Yogi Berra ↗, in Dick Young’s column (New York Daily News), carried in the Aberdeen (SD) American News — the sentence, then a dash, then Berra’s name.
  • Today — Wikiquote files the line under Disputed ↗, naming Wohlford as the first to say it, while quote sites keep printing the smoothed-out version under Berra’s name.
In copyright

Nothing here is public domain: the earliest documented printing is a newspaper column of 4 April 1974, more than four decades after the pre-1931 cutoff that governs US public domain, and the Berra-branded rewrites were printed later still. We make no claim about whether a seven-word spoken quip is itself protectable expression — only that no pre-1931 source for it exists.

Fact-check

One sentence, a queue of claimants

This is a line with a queue of claimants, and the famous one joined the queue last. Here is who has been credited, and when the paper trail says each credit begins.

Yogi Berra Disputed

The first citation crediting Berra that Popik documents ↗ is 28 January 1979 — Dick Young’s syndicated column in the Aberdeen (SD) American News, which prints the sentence and simply appends Berra’s name. That is almost five years after the line is already in print as Wohlford’s. Wikiquote lists it under Disputed ↗, not among his sourced Yogiisms.

Danny Ozark Also credited

The Phillies manager (1923–2009) picked the line up in the middle. Popik’s chronology ↗ credits it to Ozark in the Des Moines Register of 19 April 1977 and the St. Petersburg Times of 26 April 1977 — three years after Wohlford, two before Berra. Ozark was routinely lampooned for malapropisms ↗, which made him a natural magnet too.

Chuck Tanner Also credited

Three months after Wohlford, Popik’s chronology ↗ records Chicago White Sox manager Chuck Tanner saying “Baseball is 90 percent mental” in Pete Mollica’s column in the New Castle (PA) News, 19 July 1974, p. 11, col. 2. A real, dated citation — and the earliest documented printing of the “Baseball is…” opening that later travelled under Berra’s name — but still three months behind Wohlford.

“Baseball is ninety percent mental, and the other half is physical” Variant

This smoother version is what quote sites, mugs and posters actually print under Berra’s name. Popik treats it as a popular variation of the line ↗, not as the wording that was first recorded. The 1974 printing reads “Ninety per cent of this game is half mental” — “per cent” as two words, “this game” rather than “baseball,” and no second clause at all. Even the “Baseball is…” opening is first documented under Chuck Tanner’s name, not Berra’s.

The sentence that got into print first was Jim Wohlford’s, in April 1974 — and Popik’s dated chronology ↗ contains nothing earlier. Berra usually receives the credit; Wohlford said it first.

Context

Why the line ended up in Berra’s mouth

Wohlford’s sentence is a perfect specimen of a particular kind of joke — a percentage that does not add up, delivered flat. That shape had a famous owner long before 1974. By the mid-1970s Yogi Berra was already the recognised brand for cheerfully self-contradicting arithmetic, so any orphaned line with that shape drifted toward him the way loose iron drifts toward a magnet.

The paper trail shows the drift happening. In April 1974 it is a young Royals outfielder’s catchphrase. By April 1977 sportswriters are pinning it on Phillies manager Danny Ozark, another man collected for his malapropisms. By January 1979 a New York Daily News columnist prints it with Berra’s name attached and no explanation — and that is the version that stuck, because it was the one that sounded most like itself.

I really didn’t say everything I said.

But didn’t Berra claim it himself?

Complicating things: CBS Sports, citing The New York Times, reports that Berra took credit for this one in his own book ↗ — unlike “déjà vu all over again,” which he initially denied. That is worth stating plainly rather than hiding.

It does not move the earliest attestation. Berra’s claim came decades after Wohlford was quoted saying it in 1974, and a later claim by a famous man does not outrank a contemporaneous newspaper citation of an obscure one. Berra may well have said a version of it — a line this catchy gets repeated by everyone in a dugout — but saying it is not the same as coining it.

Berra himself supplied the caveat that ought to govern every page like this one. Wikiquote records, among his genuinely sourced Yogiisms, his admission that he really didn’t say everything he said.

The man who actually said it

The reserve outfielder behind the most-quoted line he never got credit for

Jim Wohlford

born 1951 · Major-league outfielder, 1972–1986 · Royals, Brewers, Giants, Expos

James Eugene Wohlford was born 28 February 1951 in Visalia, California, and debuted for the Kansas City Royals on 1 September 1972. Over fifteen seasons with the Royals, Milwaukee Brewers, San Francisco Giants and Montreal Expos he played 1,220 games and batted .260, mostly as a reserve and defensive-replacement outfielder. He never made an All-Star team — and yet his Wikipedia entry leads on the fact that he “became notable” for a single sentence that the rest of the world has spent fifty years crediting to somebody else.
