On November 3, 1953, the rules committee chose to end the practice of allowing players to leave their gloves on the playing field. Outfielders and infielders were now required to carry their gloves with them into the dugout after each half-inning. Before the controversial change, left fielders, right fielders, first basemen, and third basemen would leave their gloves in foul territory, while center fielders, shortstops, and second basemen would drop their gloves at their position. Plays on the field would take place around the scattered leather.
The rule is outlined in MLB’s Official Rules:
3.10 Equipment on the Field
(a) Members of the offensive team shall carry all gloves and other
equipment off the field and to the dugout while their team is at
bat. No equipment shall be left lying on the field, either in fair
or foul territory.
