major leagues adopt a new rule that prohibits baserunners from interfering with batted balls in the field of play

On April 25, 1957, the major leagues adopt a new rule that prohibits baserunners from interfering with batted balls in the field of play. The rule is adopted in reaction to recent actions by several Cincinnati Reds baserunners. Earlier in the week, Don Hoak and Johnny Temple had intentionally interfered with batted balls as a way of preventing double plays.
