MAJOR LEAGUE RULE CHANGES 1845 TO 1986 The following is a compilation of all the important major league rule changes that have been made since 1845. In assembling the research for this book, we found a number of small disagreements on dates; virtually all, however, occurred inthe nineteenth century, and most discrepancies were of but one year. The bracketed reference that follows some of these rules refers to the rule number in today's Official Baseball Rules. In some cases, the rule as it reads today is considerably different from the way it was written then. 1845 -Although some sources say that the first written "baseball rules" date from 1834 or 1842, a more commonly cited year of origin is 1845, when the New York Knickerbockers created a formal code of playing rules. The rules limited each team to nine players, laid out the field in what designer Alexander Cartwright termed his "baseball square" (with - 90-foot sides), and established that the winner was the team who scored 21 aces, given that each team had an equal number of turns at bat. -There are no restrictions on bat size or shape. [1.10] -The ball weighs 3 ounces. [1.09] -The pitching distance is 45 feet. [1.07] -Provisions are made for an umpire. [9.01a] 1846 -The first recorded argument between a player and an umpire.

[1.10] 1860 -Whitewash is used to mark the foul lines. [1.04] -The umpire of a game is selected by the captain of each team. He is given the authority to suspend play, and he must make a call when a ball is foul.
