On October 30, 1919 the Baseball Presidents of the American League and the National League called for the universal abolishment of the spitball. They said it gave an unfair advantage to the pitcher and was considered yucky. They agreed to allow all pitchers who were currently using the slimy pitch to continue to do so, but as of 1920, no new pitchers would be allowed to add any substance, natural, unnatural or supernatural to the baseball to cause it to dodge, duck, dip, dive or dodge.
“Spitballing” has since joined the ranks of terms such as “rewind” and “hang up” that are still in use, even though their literal meanings have become obsolete. Fortunately, Sharing Twisted-History never goes out of style.
