The earliest documented use of the phrase is Ashe’s own diary entry of 22 February 1974, printed in Arthur Ashe: Portrait in Motion (with Frank Deford), where he writes of Björn Borg that “he is in what we call the zone.” Quote Investigator ↗ found no earlier evidence — but note Ashe’s own wording, “what we call the zone,” which presents the term as slang already circulating among players.

Diary, 22 Feb 1974
In the same entry Ashe adds a parenthetical gloss, tracing the term to “twilight zone” and translating it as, more or less, another world.
Quote Investigator ↗ identifies the 22 February 1974 diary entry as the earliest evidence and quotes it in full, citing p. 201 of the Ballantine Books edition of Arthur Ashe: Portrait in Motion.
The book itself is catalogued by the Internet Archive ↗ as Arthur Ashe with Frank Deford, Houghton Mifflin, Boston, 1975.
Quote Investigator’s later citations — a Dallas Morning News piece in May 1975 and a United Press International story in March 1976 — show the phrase spreading outward from tennis with the Twilight Zone explanation attached.
The wording comes from Arthur Ashe: Portrait in Motion, first published in 1975 — well after the 1931 United States public-domain cutoff — so the diary text remains in copyright. Only the short phrase itself, too brief to be protectable on its own, circulates freely.

What gets said about this one
The attribution to Ashe is unusually well documented — but three claims regularly travel with it that the sources do not support.
✕
Coinage“Arthur Ashe coined ‘in the zone’” Overstated
Ashe’s sentence is “he is in what we call the zone” — he is glossing an in-group term for readers, not minting one. Quote Investigator ↗ credits him with popularising the expression and says he may have taken part in coining it, while noting the origin remains uncertain.
✕
Etymology“It definitely comes from The Twilight Zone” Ashe’s own gloss
That derivation is Ashe’s aside in the same 1974 entry, repeated in a 1976 United Press International story quoted by Quote Investigator ↗. It is what players believed, not an etymology established by lexicographers — Wiktionary ↗ offers no origin for the idiom.
✕
SourcingQuote cards crediting a bare “in the zone” to Ashe Unsourced
Aggregator pages pin the phrase to Ashe with no book, page or date. The actual citation is narrow and checkable: a diary entry dated 22 February 1974, printed in Arthur Ashe: Portrait in Motion ↗, written with Frank Deford.
✓Ashe is the first person known to have written the phrase down, and he wrote it about Björn Borg — but he presented it as tennis-tour slang, and Quote Investigator ↗ stops short of naming a coiner.
Context
How a tennis diary gave sport its favourite state of mind
Ashe recorded his 1973–74 season onto tape as he went — airports, locker rooms, hotel beds — and Frank Deford shaped the recordings into a published diary. The entry for 22 February 1974 is a loss: a young Björn Borg beat him, and Ashe reached for a piece of locker-room shorthand to explain why. The kid, he said, was in the zone.
Ashe glossed the term himself, tracing it to The Twilight Zone — the Rod Serling series that ran on CBS from 1959 to 1964 — and rendering it as roughly ‘another world.’ That gloss is Ashe’s explanation, not an independently established etymology, but it is the first time anyone is known to have written the phrase down and said what it meant.
He is in what we call the zone.
What happened to the phrase afterwards
Quote Investigator’s chronology shows the term spreading out of tennis over the following years: a Dallas Morning News piece in May 1975, a United Press International story carried in the Port Arthur News in March 1976 that likewise linked the expression to the science-fiction series, then sightings in the Centre Daily Times (December 1978), the Trenton Evening Times (December 1979) and World Tennis magazine (February 1982).
Today it is simply general English: Wiktionary ↗ defines it as a state of focused concentration in which one shuts out everything irrelevant, and offers no etymology at all.

1943–1993 · American tennis champion, diarist & civil-rights advocate
Arthur Ashe (born 10 July 1943 in Richmond, Virginia; died 6 February 1993) won three Grand Slam singles titles — the US Open in 1968, the Australian Open in 1970 and Wimbledon in 1975 — the first Black man to win any of them. Between Wimbledon 1973 and Wimbledon 1974 he kept a running audio diary of life on tour, published in 1975 as Portrait in Motion: The Arthur Ashe Diary, written with the sportswriter Frank Deford. That book is where the sporting sense of “the zone” first appears in print.
