MLB baseballs are made of a small cork ball, called a "pill," surrounded by two layers of rubber, followed by 150 yards of wool yarn, 50 yards of cotton/polyester yarn, and a layer of adhesive. The outer cover is made of cowhide, typically from Holstein cattle, and is stitched together with 108 stitches of red cotton thread. This information is found on the official MLB website in the section "The Composition and Creation of a Baseball" (https://www.mlb.com/news/the-anatomy-...).
