Diamond D1-PRO Baseball

Yes, the Diamond D1-PRO features the official NFHS stamp, making them fully compliant for regulation high school play.

The raised seams provide a more tactile grip, which is particularly helpful for developing pitchers who need better feedback to refine their control and spin.

These balls are built with a traditional cork and rubber core, wrapped in Grade A grey wool winding to ensure consistent flight and bounce characteristics.

This set is sold by the dozen, meaning you will receive 12 baseballs per pack.

While they are designed for game-day use with a premium leather cover, their high-quality construction makes them durable enough for team practices, though they will show wear faster if used exclusively against metal bats.
