If you've ever had the misfortune of suffering from a charley horse—a sharp muscle spasm or cramp in your leg—you might have wondered where this strange term came from. Who exactly is this Charley? What’s his connection to the pain I’m feeling?
Much like the terms flaky and jazz, the phrase likely has roots in the world of baseball. While the exact origins remain somewhat unclear, old newspaper clippings suggest that it was first used by a baseball player in the 1880s. The identity of that player and the reason behind the phrase remain mysteries.
A January 1887 article in the Democrat and Chronicle reveals that the term was already well-known in baseball circles, although to the general public, charley horses were as puzzling as “an Egyptian hieroglyphic.” That same year, charley horses were referenced in several newspapers across the U.S., with many offering their own theories on the term’s obscure origin. The Oakland Daily Evening Tribune reported that “Nearly every sporting journal gives a different version as to how the term charley horse originated in baseball circles.”
The most popular story, according to the newspaper, revolves around John Wesley 'Jack' Glasscock, a shortstop for Indianapolis. A few years prior, Glasscock had strained a tendon in his thigh during a game, and afterward, he returned to his farm where his father cared for an elderly horse named 'Charley horse.' Upon seeing his son limping, his father supposedly remarked, 'Why, John, my boy, what is the matter? You go just like the old Charley horse?' Glasscock is said to have shared this humorous phrase with his teammates, and it soon became widely known. Similar stories appeared in other newspapers, though they were often linked to different players.
Other accounts suggest the phrase has no connection to an actual horse, but instead stems from the way an injured player, while running, might resemble a rocking horse or a child riding a wooden hobby horse.
In his book The New Dickson Baseball Dictionary, Paul Dickson mentions other theories. One involves players from the Orioles or Chicago Cubs who bet on a horse named Charlie that 'pulled up lame in the final stretch.' The following day, a player who suffered a leg injury was said to look like 'our old Charlie horse.'
Another possibility is that the term originates from an old workhorse used to pull a roller across the infield. According to Tim Considine in 1982’s The Language of Sport, 'Old workhorses' kept at ballparks were often called Charley. The stiff-legged, slow-moving players were compared to these horses, and their injuries eventually became known as 'charley horses.'
Initially, the term charley horse may have referred to a more severe injury, or perhaps it was associated with the anxiety surrounding a new and alarming condition in the late 19th century. An article from the Democrat and Chronicle described it as a 'giving way of one of the small tendons of the leg,' and stated that an injured player might need an entire season to recover. Another 1887 article noted how George Van Haltren’s relatives were worried he would get a charley horse, even though they didn’t know what it was. He was considered 'very fortunate' for not yet having encountered the dreaded charley horse.'
In contrast, Healthline.com now explains that charley horses 'are generally treatable at home' through methods like stretching, massaging, or icing the affected area, although the muscle soreness can persist for up to a day in some instances. So, there you have it. While the true origin of the term 'charley horse' may remain a mystery, the next time you feel a sharp pain in your leg, you can thank a vintage ballplayer for giving your discomfort such a quirky name.
