  • Each baseball has 108 stitches.
  • The stitches give pitchers something to grip onto.
  • The AL and NL standardized baseballs in 1934.

It would be much trickier to evaluate the baseball betting markets at the BetMGM sportsbook if baseballs weren’t standardized. The American and National League only agreed to standardize the manufacturing process in 1934, and balls have only been provided by Rawlings since 1976.

A regulation baseball has 108 stitches. 

This is the same, regardless of how many baseballs are used in an MLB game

Why Do Baseballs Have 108 Stitches?

Baseballs have exactly 108 stitches to ensure consistency when multiple balls are used within a game. 

The stitching gives somewhere for pitchers to grip the ball and impart spin. The ball’s aerodynamic properties are altered by the number of stitches, which create drag as the ball travels through the air.
