Baseball The Ball
A baseball is a sphere made of yarn wrapped tightly around a small, round piece of cork or rubber. The sphere is then covered with two pieces of white leather that are sewn together with red thread. A regulation baseball measures 9 to 9.25 inches in circumference and is about five ounces, the perfect size to fit right in your hand. It may be small, but it's densely packed, getting hit with a baseball will definitely leave a mark. Though the standard baseball can be used by all ages, younger sluggers might start with a softer tee ball to get started.
