The following is a brief description of the responsibilities for each member of the umpiring team on a 90' diamond.

(NOTE: This is a GENERAL GUIDELINE. Some umpires use slightly different coverage systems depending on skills level and experience. It is VERY IMPORTANT to hold an umpire conference before the game to make sure both umpires are on the same page as far as coverages on the field is concerned.)
