Highlighted LL Rules for DMLL Umpires + DMLL AAA/AA Local League Rules


2019 rule changes above include the following:

Regulation VI 

(a) Any player on a regular season team may pitch. Exception: Any player who has played the position of catcher in four (4) or more innings in a game is not eligible to pitch on that calendar day. 

A player who played the position of catcher for three (3) innings or less, moves to the pitcher position, and delivers 21 pitches or more in the same day, may not return to the catcher position on that calendar day. Exception: If the pitcher reaches the 20-pitch limit while fcing a batter, the pitcher may continue to pitch, and maintain their eligibility to return to the catcher position, until any one of the following conditions occur: (1) that batter reaches base; (2) that batter is retired; or (3) the third out is made to complete the half-inning or the game.

(what changed?: the catcher moving to pitcher - with fewer than 4 innings played as catcher - may now only return to the catcher position if they pitch fewer than 21 pitches)


Rule 2.00

DEAD BALL AREA is the area beyond any intended physical boundary, such as a fence, rope, chalk line, any stands, bleachers, dugouts, player's benches, or designated media areas, or any other boundary line as determined in the pregame conference.  If a ball becomes lodged in fence, backstop, umpire's equipment, or catcher's equipment, it is considered to be in a dead ball area.

(what changed?: there are no longer any "catch and carry" areas)

Also, sometimes it's desirable to use Dickies work pants for the umpire uniform.  They are durable, relatively inexpensive, and easy to care for.  Please seek out gray (charcoal gray preferred over light gray).  These are available at Dickies outlets in San Diego County, as well as online, including the Dickies website:

Adult sizes: https://www.dickies.com/mens-clothing/mens-pants/gray/
Youth sizes: https://www.dickies.com/boys-clothing/boys-pants/gray/


If you have any questions regarding any of the above, please let me know.  Thank you for spending time to review the resources above.  I look forward to seeing you on the ball field!
