Mark 1 Official League Flat-Seam Baseballs (12-Pack)

Description

The Mark 1 flat seam baseballs are official league-size balls with a low-profile seam design that reduces wind resistance in flight. Covered in leather and sold in a 12-pack, these flat seam baseballs are used by recreational leagues, youth organizations, and school programs that want a game ball with a smoother surface profile than traditional raised-seam construction. The flat seam design also tends to produce a truer flight path on throws and hits, making it a popular choice for younger players developing their mechanics.

Flat seam baseballs behave differently than raised-seam balls in several ways that matter to coaches and players. The lower seam profile means less aerodynamic disruption, so pitched and thrown balls tend to stay on a more predictable trajectory. For hitters, the smoother surface can produce slightly different spin rates off the bat compared to a raised-seam ball. Many youth and amateur leagues have adopted flat seam baseballs as their standard because the reduced seam height is easier on younger arms and produces more consistent ball flight during games.

For leagues and programs that prefer the traditional raised-seam construction, the Mark 1 raised-seam official league baseball offers the same leather cover with standard stitching height. Teams looking to stock practice balls in bulk can also browse MacGregor leather practice baseballs or the Wilson flat-seam practice baseball for a training-focused flat seam option.
