Going with the idea of baseball and the 25% weight reduction, going from a softball to a baseball is a 25% weight reduction.
A softball can range in size anywhere from 6.25 to 7 oz. The largest weight I found online was 7 oz.
A standard Major League Baseball weighs between 5 and 5.25 oz.
So if you take the largest possible size of the two balls, 7 and 5.25 oz. that is EXACTLY a 25% weight reduction.
So could this mean we must score both baseballs and softballs into goals? Or maybe we'll play baseball with specific softball rules? I'm not familiar with softball rules, they may be the same as baseball. Anyway... this is too much of a coincidence to just pass up.
