One of the most important aspects of umpiring, at any level, is game management. In the link below, you will find a number of handouts that will provide valuable information to this end.
Units are free to use any of this material, provided authors, where noted, are cited. The Jim Evans material is an adaptation of a handout from a Jim Evans training session. Jim umpired 29 years in the American League and has trained professional and amateur umpires from 22 countries. Umpiring Axioms is also a copyrighted product from training conducted by Jim Evans. Many of Jim's graduates are Major League umpires today.
Any material not cited is provided by state rules interpreter Ken Allan and does not need to be attributed.
