Sidd Finch — a magazine invented a 168-mph pitcher and hid the confession in the headline

In its issue dated 1 April 1985, Sports Illustrated published “The Curious Case of Sidd Finch,” a long feature by the writer George Plimpton describing a mysterious New York Mets pitching prospect who could throw a fastball 168 miles per hour with pinpoint control. The pitcher did not exist. Hayden Siddhartha “Sidd” Finch was an invention — an April Fools’ Day hoax commissioned by managing editor Mark Mulvoy after he noticed the issue would be dated 1 April, and written by Plimpton with the full apparatus of Sports Illustrated‘s reporting: photographs, named teammates, and a detailed, sober narrative voice.

The story was elaborate. Finch was said to have been raised in an English orphanage, orphaned again when his adoptive archaeologist father died in a Nepalese plane crash, schooled briefly at Harvard, and trained in the mountains of Tibet, where he had learned through yoga to harness “siddhi” — perfect mastery of mind and body — into a delivery faster than any human arm had produced. He pitched, it was reported, while wearing a single heavy hiking boot, and was torn between baseball and the French horn. A junior-high art teacher from Oak Park, Illinois, named Joe Berton, posed for the photographs, usually with his face turned away. The whole confection rested on a single embedded confession: the article’s subhead read, “He’s a pitcher, part yogi and part recluse. Impressively liberated from our opulent life-style, Sidd’s deciding about yoga — and his future in baseball.” The first letters of those words spell “Happy April Fools’ Day — a(h) fib.”

Many readers missed it. Mets fans deluged the magazine with requests for more information; the magazine reported that two major-league general managers telephoned the commissioner’s office, a Florida newspaper dispatched a reporter to find Finch at the Mets’ spring camp in St. Petersburg, and the television networks scrambled. Yankees owner George Steinbrenner reportedly fumed that the stunt was “bad for baseball.” Sports Illustrated let the joke ripen for two weeks, ran a mock “retirement” notice on 8 April, and admitted the hoax outright in the issue dated 15 April 1985.

The case is studied less for the absurdity of a 168-mph fastball — well beyond the roughly 100-mph ceiling of real pitchers — than for the precision of its engineering. It married the unimpeachable credibility of a national magazine and a celebrated author to a fantasy its audience desperately wanted to be true, and it printed its own confession in plain sight, trusting that belief would override reading.
