How fast did Baseball pitchers throw in the 1930's?

In the 1930s, Baseball pitchers typically threw fastballs in the range of 80 to 90 miles per hour. While some exceptional pitchers, like Bob Feller, were known for their speed and could exceed these averages, the overall velocity of pitchers during this era was significantly lower than today's standards, where many pitchers consistently reach speeds above 95 miles per hour. The technology and training methods of the time also limited the ability to measure and maximize pitch speed accurately.
