The MLB sent a memo to all 30 teams Tuesday enforcing uniformity on one crucial process: muddying baseballs.
In an effort to "ensure consistency amongst all 30 clubs," the league sent the memo to require adherence to the specific procedures they deemed best for "baseball mud application."
The process of muddying a baseball is crucial for pitchers to maintain a proper grip on the ball. Clubhouse attendants have overseen the mud application for years, utilizing a unique mud from the Deleware River to remove glossiness from new baseballs.
But as the league cracks down on the use of foreign substances, video obtained by the league showed a lack of consistency clubhouse-to-clubhouse for how the muddying process was done.
According to the MLB, the proper way to mud a baseball is to apply the mud directly by hand "in a uniform manner ensuring the same mud to water ratio is applied to each ball," the memo reads. This process should take at least 30 seconds for each ball in order to ensure the mud is rubbed thoroughly into the leather surface.
The timing of the mud application was another element the league sought to make uniform. According to the memo, all muddying must be done within three hours of all other baseballs being used in that game, and they must be mudded on the same day they will be used.
The memo went on to specify how the balls are to be stored and how they should be prepared for each game. A "Rubbing Mud Application Poster" will also be placed in each clubhouse to ensure consistency with the color of the ball.MLB sends detailed memo to teams requiring specific techniques when 'muddying' baseballs - The Athletic View Story
