The baseball is actually quite complicated to manufacture. In the center there is a cork core called the pill. The pill is then wrapped in almost 300 meters of different types of wool. The center piece is then covered in adhesive and two 8 shaped pieces of white tanned leather are then placed on the adhesive. The ball then needs to be hand stitched for more than 10 minutes with a red cotton thread.

Baseballs were originally homemade and baseball was originally only played by milkmaids (women who milked cows). The old baseballs were made of brown leather and also had a solid core. It also wasn't feasible to make them perfectly round.

At one it was part in time, it wasn't against the rules to pelt other players with a baseball (they were however far lighter).

They litteraly rub mud on white balls to give the pitchers more grip and control... (it's even done in major league baseball).
