Balls are made by hand in Central America at a Rawlings factory. At a baseball's core is a small rubber ball called the “pill”. Around this pill, a layer of gray yarn is wound. Next up comes a cream colored and then another layer of gray. Its finished off with a thin, white thread. In all, some 130 yards of yarn are needed to build the core to regulation size. From there, two leather outers are stitched with the familiar red thread, the ball is stamped with logos and a game-ready Major League baseball is born.
