A Horse Named Charley

Charley Horse. A muscular pain, cramping, or stiffness that results from a strain or bruise.

— Webster's Dictionary

In March 1886, a sportswriter for The Louisville Courier-Journal reported that a local baseball player was suffering a "brand new disease" called a Charley Horse.

In fact, sportswriters around the country had been reporting many instances of the new disease.

A writer for The Boston Globe reported that the disease would cause a ballplayer to run around the field "after the fashion of a boy astride of a wooden horse, sometimes called a Charley Horse."

But what, readers wondered, was a pro baseball Charley Horse?

A writer for The Wheeling Intelligencer unearthed the answer:

"The disease consists of a peculiar contraction and hardening of the muscles and tendons of the thigh, to which ballplayers are liable from sudden starting and stopping in chasing balls. 

"Shortstop Jack Glasscock is said to have originated the name because the way the men limped around reminded him of an old horse he once owned named Charley."

While they agreed on the symptoms, not all sportswriters accepted the name's origin story.

A sportswriter for The Chicago Tribune attributed the name to horse racing, where a lame horse was called a "Charley."

A writer for The Grand Rapids Daily Democrat said the name came from manufacturing, where lame horses called "Charlies" were used to pull carts.

And a writer for The Washington Post said that the name came from a ballplayer,  Charlie "Hoss" Radbourn, who often experienced leg cramps while running bases.

While it might seem odd that sportswriters of the 1880s would label Charley Horse a disease, keep in mind that physicians today say that frequent Charley Horses—especially the nocturnal kind—can signal other, fatal diseases, including alcoholism, ALS, cardiovascular disease, cirrhosis, diabetes, kidney failure, Parkinson’s, MS, and lung cancer.
