The Evolution Of Baseball
The Evolution Of Baseball

1. Dead Ball Era

It was at the end of the 1870s when baseballs made with rubber at the core were used. The games were played with a single ball for the entire game till unraveled. These balls caused a visibility problem for the players when covered with dirt. In addition, batters were not able to hit the ball at a distance.

To overcome these challenges, from 1910, a new ball was introduced having cork cores instead of rubber. But still, using rubber balls continued till 1920. The name dead ball era comes from the fact that the games played involved a dead or softball in this era. The dead ball meant it couldn’t travel far or fast when hit by the batters. 

These balls were manufactured by A.G. Spalding sporting goods company, co-founded by Albert Goodwill Spalding, an American pitcher, manager, and executive during the early times of professional baseball. Less rubber and looser windings went into the making of these balls, and they weighed around 3+⅛ oz at that time.

2. Live Ball Era

1920 marks the beginning of this era when wool from Australia got introduced as the outermost yarn layer for baseball. It continued till 14 years when in 1934, the American and National Leagues set a standard manufacturing process and decided to keep the weight of the ball by about 8.9 gms and the size of 20 cms in circumference.

The layers of the ball comprised of core, cushion, red rubber, black rubber, wool yarn, and tanned horsehide, which added another 9 gms to the ball’s weight.

3. World War II

World War resulted in the scarcity of rubber. Since baseballs were put into non-essential commodities, obtaining raw materials for production of baseballs was difficult. This situation compelled the manufacturers to use granulated cork instead of rubber, also known as balata. This baseball comprised two shells of cork wrapped at the core.

Those days were very dynamic, leading to the continuous evolution of baseball. In 1944, the baseballs were uniformly manufactured on a large scale as mass production was possible. With specifications from the Live Ball era, the production of baseballs were done using synthetic rubber.

4. Present Day

Today, the baseball used professionally has a core made out of cork and rubber, wrapped in black rubber, then red rubber, and covered by a coat of yarn. The outer covering till 1974 was of horsehide eventually getting replaced with cowhide.

The average weight of a baseball ranges from 142 grams to 149 grams as per MLB’s specifications. Other versions of the baseball used for different purposes and age groups and vary in design, size, and weight. The following table will help you to distinguish in a better way.
