What is the Definition of a Glove in Baseball?

Baseball gloves, also known as mitts, are essential pieces of equipment for players in the popular sport of baseball. These gloves are traditionally made of leather, although other modern materials are also utilized and worn by the defending team to help catch and field balls hit by a batter or thrown by a teammate. The usage of gloves in baseball has come a long way since the sport’s beginnings, when it was played bare-handed. The introduction of gloves initially started with catchers in 1860, followed by first basemen, and eventually was adopted by players in all positions.

There is a variety of baseball gloves available, each designed specifically for positions such as infield, outfield, first base, and catching. They vary in size and pocket depth to cater to the unique demands of each position. For example, infield gloves typically have smaller sizes and shallower pockets for quick plays. Glove sizing and fit are crucial as well, with youth players using gloves ranging from 10.75 to 11.75 inches, while high school to adult players use gloves between 11.25 to 12.25 inches. Proper maintenance and care are vital to ensuring the longevity and performance of a baseball glove, which involves regular cleaning, conditioning, and adjustment for a perfect fit.

History of Baseball Gloves

Early Days

In the early days of baseball, gloves were not a standard part of the game. It is believed that one of the first players to use a baseball glove was Doug Allison, a catcher for the Cincinnati Red Stockings, in 1870, due to an injured left hand1. The first confirmed glove use was by Charlie Waitt, a St. Louis outfielder and first baseman who, in 1875, donned a pair of flesh-colored gloves1.

As the 19th century progressed, gloves gained popularity and became more common among baseball players. By the 1890s, most players were using gloves to protect their hands and enhance their gameplay.

Modern Developments

Glove innovation moved slowly until the 1920s, when a significant advancement occurred. In 1920, St. Louis Cardinals’ pitcher Bill Doak introduced a design that replaced the crude webbing in gloves with a more functional and efficient design2. Doak’s web design between the thumb and pointer finger became a gamechanger as it made catching the ball easier. This advancement truly solidified the glove’s purpose not only as hand protection but also as a tool to improve players’ performance3.

Since then, baseball gloves have continued to evolve in terms of materials, design, and position-specific functionality. Modern gloves are now customized according to a player’s position, skill level, and personal preference, providing the best possible performance on the field.

Types of Gloves

Catcher’s Mitt

Catcher’s mitts are specifically designed for the catcher position in baseball. They are measured in circumference and have an oval-shaped pocket. Most catcher’s mitts feature a closed web design and additional padding compared to a traditional fielder’s glove, providing extra protection and durability.

First Baseman’s Glove

First baseman’s gloves are designed to provide easy scooping ability to pick up ground balls and a deep pocket for catching throws from other infielders. They usually feature extra padding and a slightly curved design to help with scoops and holding onto the ball securely.

Infielder’s Glove

Infielder’s gloves are designed for second basemen, third basemen, and shortstops. These gloves are smaller in size and have a shallower pocket than pitcher’s gloves and outfielder’s gloves. This allows infielders to quickly transfer the ball from the glove to their throwing hand for faster, more accurate throws.

  • Second Basemen: Typically have the smallest gloves of all infielders, allowing for quick maneuvers and transitions.
  • Third Basemen: Need slightly larger gloves with sturdier padding and deeper pockets to handle hard-hit balls and to provide protection against high-velocity line drives.
  • Shortstops: Require gloves with a balance between size and comfort, allowing for quick transfers and a good range.

Outfielder’s Glove

Outfielder’s gloves are designed with a deeper pocket and longer length to help catch fly balls and make running catches. They are typically larger than infielder’s gloves, which provides additional reach for outfielders to cover more ground.

Pitcher’s Glove

Pitcher’s gloves are unique in that they are designed to disguise the grip on the ball and minimize distractions for the batter. They are generally lightweight with a closed web design and are very similar in size to an infielder’s glove. This enables pitchers to make quick and accurate throws to any base.

Materials and Construction


Leather is the most common and preferred material used in manufacturing baseball gloves. There are a few types of leather typically used, including full grain, kip leather (kipskin), and steerhide. Each type provides its own unique feel, durability, and break-in period. The premium leather used in gloves, like Wilson’s Pro Stock and Pro Stock Select Leather, is sourced from the most consistent and high-quality hides in the world, ensuring a great feel and perfect break-in.

Synthetic Materials

Though leather is the preferred material for making baseball gloves, synthetic materials like nylon and vinyl are also incorporated in certain parts of the glove. For example, synthetic materials might be used as a lining for the back of the glove, providing additional comfort and breathability without compromising the overall performance of the glove.


Padding is an essential component of a baseball glove as it helps reduce the impact of the ball on the hand. The padding is usually inserted during the manufacturing process, along with any required plastic reinforcements, which provide additional support and durability. The type and amount of padding can vary depending on the glove’s position and usage, as catcher’s mitts and first base mitts may require more padding than outfield gloves.


Baseball gloves are stitched together by sewing the leather pieces, as well as any synthetic materials, to form the shell of the glove. The web, which is made from several pieces of leather, is also stitched together before being laced to the glove’s other parts. High-quality gloves often use nylon threads to strengthen the stitching and ensure that the glove remains durable throughout its lifespan.

By carefully selecting materials and employing precise construction techniques, baseball gloves can provide optimal performance, comfort, and durability for both professional and amateur players.

Glove Sizing and Fit

Measuring for Size

To choose the right baseball glove size, it’s essential to understand the basic anatomy of a glove. Components like index finger, thumb, and web design play a role in determining the proper size for the player. Glove sizes are measured in inches, ranging from 10.75 to 12 inches depending on the player’s age. It’s worth mentioning that fielder’s gloves and catcher’s mitts are measured differently, so a player should be aware of the difference.

Youth gloves come with smaller wrist openings and shorter finger stalls compared to adult baseball gloves. Below is a handy reference for determining glove sizes:

Breaking in a Glove

Breaking in a baseball glove is essential to ensure optimal fit, performance, and comfort. There are various methods players can use, but here are some tried-and-tested techniques:

  • Playing Catch: The most effective way to break in a glove is to play catch frequently. This method helps to form the pocket and shape the glove naturally over time.
  • Glove Conditioning Oils: Applying a small amount of glove conditioning oil to the leather can aide in the breaking-in process. It’s essential to not overdo it, as excess oil can negatively affect the glove’s structure.
  • Steaming: Some stores offer glove steaming services. Steaming the glove and then playing catch can help break in the glove more quickly.
  • Mallet: Gently pounding a mallet on the glove pocket can help with the breaking-in process. This method can form the pocket without causing unnecessary stress to the glove’s leather.

Remember, it is crucial to avoid using shortcuts or drastic methods when breaking in your glove, as they can cause damage or shorten the glove’s lifespan. Patience and care will produce the best results.

Maintenance and Care


To properly maintain your baseball gloves, it’s important to clean them regularly. After each use, remove the excess dirt and debris from the gloves using a brush or clean rag. For a more thorough cleaning, use a damp cloth or sponge with mild soap, like dishwashing liquid or baby shampoo. Gently rub the cloth against the surface of the glove in circular motions to remove dirt and debris from the crevices on its exterior. Be careful not to soak your glove, as too much moisture can damage the leather.

In addition to regular cleaning, make sure to use a leather-safe cleaner to prevent any damage or gunk build-up. Also, apply a glove conditioner approved for use on baseball and softball gloves to maintain your glove’s flexibility and longevity.


Proper storage plays a key role in maintaining the life and quality of your baseball glove. Store your glove between uses on a shelf in a cool, dry place or at room temperature. Moreover, it’s essential not to leave your glove sitting around outside, near a heater, or in your equipment bag, as exposure to extreme temperatures or humidity can damage the leather.

Following these simple maintenance and care steps will ensure your baseball gloves stay in top condition and offer optimal performance on the field.


In the game of baseball, gloves serve an important function for batters and fielders, offering improved grip and protection from impact. The use of batting gloves has become a popular addition to modern baseball, offering better traction and grip on the bat. This added grip allows players to enhance their control when swinging, impacting their overall batting performance.

Wearing gloves in baseball also reduces the chance of injury, lessening the shock that is transmitted from the ball to the batter’s hands. A sustained impact from fast pitches and hard hits can become painful and potentially damaging to players’ hands.

Baseball gloves vary in materials, which include full grain, kip leather, and steerhide. Different types of gloves cater to infield and outfield positions, as well as specialized gloves for catcher’s mitts, first base mitts, and training purposes.

In summary, the use of gloves in baseball is crucial for players to maintain a solid grip on their equipment, improve batting performance, and also protect their hands from injury. These gloves have become an essential part of the game, making their presence indispensable on the field.
