The baseball is the central element of the sport, around which all the action on the field revolves. This small sphere is designed with specific features to ensure optimal performance during play, and its construction has evolved over the years to improve durability and control.

The baseball is composed of a central core structure (usually cork or rubber) surrounded by multiple layers of yarn and finally covered by a layer of white leather, with red “C”-shaped stitching. The stitching not only serves an aesthetic purpose, but also plays a crucial role in how the ball behaves when thrown and hit. These stitching allows pitchers to better control the ball, giving them the ability to hit spin-heavy pitches such as curveballs, sliders, or fastballs. A standard baseball weighs between 5 and 5.25 ounces (approximately 142 to 149 grams) and has a diameter of 9 to 9.25 inches (23 to 23.5 cm). This size and weight allow batters to achieve powerful hits, while pitchers have the control needed to execute their strategies. The design of the ball also has a direct impact on the dynamics of the game. Depending on the quality of the ball and the game conditions, a slight difference can be noticed in the speed, bounce, and behavior of the ball during pitching. In addition, baseballs are strictly regulated by sports organizations, such as Major League Baseball (MLB), to maintain fairness in the game.

In short, the baseball is more than just an object; it is a key piece of equipment that influences the game and the technique of players. Its design and features make it an essential tool for developing the skills of hitters and pitchers.
