This code of Rules governs the playing of Baseball games by professional teams of Major League Baseball and the leagues that are members of the National Association of Professional Baseball Leagues. We recognize that many amateur and non-professional organizations play their games under professional Rules and we are happy to make our Rules available as widely as possible. It is well to remember that specifications as to fields, equipment, etc., may be modified to meet the needs of each group. Money fines, long-term suspensions and similar penalties imposed by this code are not practicable for amateur groups, but officers and umpires of such organizations should insist on strict observance of all the Rules governing the playing of the game.

5 Baseball not only has maintained its position as the National Game of the United States, but also has become an International Game being played in more than 100 countries. The popularity of the game will grow only so long as its players, managers, coaches, umpires and administrative officers respect the discipline of its code of Rules . iv 2017 Official Baseball Rules_2017 Official Baseball Rules 3/27/17 8:58 PM Page v IMPORTANT NOTES. (1) The Playing Rules Committee, at its December 2014 meeting, voted to reorganize and recodify the Official Baseball Rules into a more logical and organized manner. No wording or language was changed (other than the amendments made for that year); only the order and place- ment of the Rules were modified. Throughout the text of this 2017 . edition, each rule number and Comment is followed by, in paren- theses, the corresponding 2014 rule number from which the new . rule originated. In this edition Comments to the Rules are high- lighted in a shaded box rather than being printed in smaller typeface as had been the case in prior to 2015.

6 In addition, at the end of this book (pages 158-160) is a cross-reference table that shows each 2017 rule and the corresponding rule number from the 2014 edi- tion (and vice versa). (2) The Playing Rules Committee, at its December 1977 meeting, voted to incorporate the Notes/Case Book/Comments section directly into the Official Baseball Rules at the appropriate places. Basically, the Case Book interprets or elaborates on the basic Rules and in essence have the same effect as Rules when applied to particular sections for which they are intended. This arrangement is designed to give quicker access to any written lan- guage pertaining to an Official Rule and does not require a reader to refer to different sections of the Official Baseball Rules book in con- sidering the application of a particular rule. v 2017 Official Baseball Rules_2017 Official Baseball Rules 3/27/17 8:58 PM Page vi Summary of Rule Changes for 2017 .
