And yeah, MLB and Japan use slightly different sized balls. Our baseball hasn't changed since 1920, and whether it did even then is debatable.
The ball during the steroid era is nothing like the ball they used then. The ball has changed a lot over the years. The ball during the steroid era was wound so tight that they seams were indented.
Players today are still well built and they're still taking PED's, but they're not hitting 70 HR's a year anymore. Why?
