Official League Baseballs from Diamond are a great choice for either youth game play, or high school practice. The Diamond "DOL-1 OL" baseball has a cork and rubber core for excellent durability. The core is wrapped with yarn as an added layer of protection. These baseballs may not be used for sanctioned high school game play. For a great high school game ball at a fair price, please see the Diamond DOL-1 HS baseball with the NFHS and NOCSAE certification stamps.
