Sidd Finch is a fictional baseball player, the subject of the notorious article and April Fools' Day hoax "The Curious Case of Sidd Finch" written by George Plimpton and first published in the April 1, 1985 issue of Sports Illustrated. According to Plimpton, Finch was raised in an English orphanage, learned yoga in Tibet, and could throw a fastball as fast as 168 miles per hour (270 km/h).
In early 1985, Mark Mulvoy, the managing editor of Sports Illustrated, noticed that a cover date that year would fall on April 1. He asked George Plimpton to commemorate this with an article on April Fools' Day jokes in sports. When Plimpton found himself unable to find enough examples to craft an article, Mulvoy gave Plimpton permission to create his own hoax.
Plimpton reported that Hayden Siddhartha "Sidd" Finch was a rookie baseball pitcher in training with the New York Mets. He also wore only one shoe—a heavy hiker's boot—when pitching. Finch, who had never played baseball before, was attempting to decide between a sports career and one playing the French horn. What was astonishing about Finch was that he could pitch a fastball at an amazing 168 miles per hour (270 km/h), far above the record of a "mere" 103 miles per hour (166 km/h), with pinpoint accuracy, and without needing to warm up. The Mets scouting report gave Finch a "9" on fastball velocity and control: "8" is the highest score on the scale.
According to Plimpton, Finch grew up in an English orphanage and was adopted by an archaeologist who later died in a plane crash in Nepal. After briefly attending Harvard University, he went to Tibet to learn "yogic mastery of mind-body" under "the great poet-saint Lama Milaraspa", which was the source of his pitching prowess. Finch decided not to pursue a baseball career, instead choosing to "play the French horn or golf or something."
