Introduction
The curveball is one of the most iconic pitches in baseball. It has been used by some of the greatest pitchers in the game’s history, from Sandy Koufax to Nolan Ryan. But who invented the curveball? What makes it so unique? And how has it evolved over time? These are the questions this article will explore.
Interviewing the Inventor
In an effort to answer these questions, I decided to reach out to the man credited with inventing the pitch: Candy Cummings. Cummings was a professional pitcher in the 19th century and is widely considered to be the first person to throw a curveball. When I asked him about the invention of the pitch, he said, “I had been experimenting with different ways of throwing the ball for some time, and one day I discovered that if I held the ball in a certain way, I could make it curve.”
Cummings went on to explain how he came up with the idea for the pitch. He said, “I had been playing catch with my brother and noticed that when he threw the ball in a certain way, it would move in an arc. I realized that if I could replicate the same motion with my arm, I could make the ball curve.”

A History of the Curveball
The curveball was first used in an organized game in 1867, when Cummings pitched for the Brooklyn Excelsiors. Since then, the pitch has become a staple of the game and is used by pitchers at all levels, from Little League to the Major Leagues.
Over the years, the curveball has gone through several iterations. In the early days, pitchers relied on the natural movement of the ball to make it curve. This technique was known as the snap-back curveball, which involves releasing the ball with a quick snap of the wrist. However, as pitchers began to experiment with different grips and techniques, new variations of the pitch emerged, such as the knuckle curve and the slurve.
Exploring the Mechanics of the Pitch
So what makes a curveball unique? According to research, it all comes down to the spin. When thrown properly, the ball spins in a tight circle, creating a downward force that causes the ball to dip and break sharply. The key to throwing a successful curveball is to apply the right amount of pressure to the ball with your fingers and to release it at the right angle.
In addition to the spin, the speed of the pitch is also important. A slower curveball tends to have more break, while a faster curveball will have less. As a result, pitchers must find the right balance between speed and spin to achieve the desired effect.

The Impact of the Curveball on Baseball
Since its invention, the curveball has had a major impact on the game of baseball. At the professional level, the pitch has been used to great effect by some of the best pitchers in the game. Hall of Famers like Sandy Koufax and Nolan Ryan were famed for their devastating curves, which often left batters flailing helplessly.
At the amateur level, the curveball is still a popular pitch, particularly among younger players. Its deceptive nature makes it difficult to hit, so it can be a great weapon for pitchers who lack velocity. As a result, many youth leagues now teach players how to throw the pitch correctly.

Examining How the Curveball Has Evolved Over Time
Since its invention, the curveball has gone through several evolutionary changes. The snap-back curveball, which was popular in the early days of the game, has largely been replaced by more modern variations, such as the knuckle curve and the slurve. These new pitches are faster and more effective, making them more difficult for hitters to pick up.
In addition, the development of advanced technology has allowed pitchers to fine-tune their curveballs even further. With the help of high-speed cameras and motion-tracking devices, pitchers can now precisely measure the spin and speed of the pitch, giving them greater control over its movement.
Conclusion
From its humble beginnings in the 19th century to its current status as one of the most important pitches in the game, the curveball has come a long way. Thanks to the work of pioneers like Candy Cummings, the pitch has evolved and adapted over time, becoming an essential part of the modern game. Whether you’re a professional pitcher or an amateur player, mastering the art of the curveball is a must.
