New Rules Baseball is a hypothetical concept proposed by the independent Atlantic League to test various experimental rules in professional baseball. These experimental rules were aimed at enhancing the game's pace and excitement. However, the concept of "median sprint speed" was not mentioned in relation to New Rules Baseball at that time.
Median sprint speed refers to the middle value in a set of sprint speed data, representing the point at which half of the values are above and half are below. Sprint speed is a metric used in baseball to measure a player's maximum running speed, typically recorded in feet per second (ft/s).
Since the implementation and testing of New Rules Baseball could have evolved or changed , I recommend checking recent news, official Atlantic League announcements, or reputable sports sources for the most current information about New Rules Baseball and any associated metrics, including median sprint speed statistics.
