Diamond Baseballs are among the most popular of elite baseballs in play today. This Diamond Sports Baseball features new DriCore technology which helps prevent a baseball from absorbing water and gaining weight in wet field conditions. If a ball is subjected to extreme water conditions DriCore will accelerate the drying time, making the baseball playable sooner. Additional features of D1-PRO-NFHS Professional League Diamond baseballs include a cushioned cork center, A-1 Grade grey wool winding, premium leather cover and Diamond Seam (raised seams). This Diamond baseball is NFHS approved and is sold by the dozen only.
