A baseball is made by wrapping yarn around a cork or rubber centre. The ball is then covered with tightly-sewn cow or horse hide. The ball measures 9 inches in circumference, and weighs about 5 ounces.

Although the baseball is not overtly heavy, the speed at which it is pitched makes it a potentially lethal object! It can also have a tremendous impact when caught. So make sure you are well protected against any impact.

In the game of hardball, the ball is smaller and denser while the bat has a harder density and is of a lighter weight. During hardball, the pitcher pitches overhead. In the game of softball, the ball is larger and has a softer density.

During this game of baseball, the pitcher pitches underhand. Both types of balls are made of similar materials.
