Umpire Registration

All umpires must register so they can go thru the 1-minute online registration process which includes compliance with the Little League background check requirement for adults; junior umpires are exempt from the background check. Your social security and driver’s license numbers are required for the background check (this is a Little League requirement), but this information will be destroyed once the background checks have been completed. Umpires Register Here!


Required & Recommended Training

All umpires MUST complete the free Little League SafeSport training. Adult Umpires can register here. Junior Umpires can register here. After finishing the training, please send a .pdf copy of your certificate to the Co-UIC’s.

We offer an Umpire Mechanics Clinic at the start of the Spring season. Information on upcoming clinics will be posted on this page.

Rules clinics are offered by D4 and are online only. You can register here for the recorded and live sessions. It is STRONGLY RECOMMENDED that you watch the rules sessions, including the mechanics clinic.

Little League University Umpire videos and training



All fields will have umpire bags which include shin guards, chest protectors, plate brushes, ball bags, and ball/strike indicators. NEVER umpire a game behind the plate without wearing a complete set of protective equipment, including a hard cup for males. FOR SAFETY AND HEALTH REASONS, WE WILL NOT BE PROVIDING UMPIRE MASKS IN THE EQUIPMENT BAG. All Umpires can choose to either purchase a mask or borrow a mask FOR THEIR OWN PERSONAL USE from NOLL/SOLL. (Purchased masks are eligible for reimbursement, see below.) MASKS WILL BE AVAILABLE FOR LOAN OR PURCHASE. Contact Bill Karpowicz or Angela Noury to get your mask!

The 2022 rules book is available as an app at both the Apple Store and Google Play. Download a copy and have it handy. The app updates automatically when rules are updated by Little League International.

For general information about California D4 umpires visit the D4 site.

All umpires are encouraged to register for the Little League Umpire Registry. It is free and there is a wealth of information designed to make you a better umpire. For general information about Little League umpires visit the Little League site.

NOLL/SOLL will reimburse you up to $100 per year for umpire clothes, shoes, or equipment purchased. Send receipts or other proof of purchase to the Chief Umpires.

Request games here. You will receive an email confirming your request and, normally within a few days, another email assigning you the game or denying the request with an explanation (for example, someone else had requested it first.)

We want to assist the development of our newer umpires, especially at the AA and AAA levels, by having them work games with experienced umpires. You will see mentor-available games posted on the website when requesting games. For some games, a mentor can even work with two of you as a team (e.g., you and your child, or you and a friend). Umpires wanting mentoring should look for these games and will get priority for approval to do them. There will also be mentoring opportunities posted for people wanting to move up to the big diamond, where there are steals, balks and leading off. You can request a mentor for games at any level, including Majors and Juniors. To request a mentor or find out more, contact the Chief Umpires.

For payment, send an email to that includes:
(1) your name and address,
(2) time, date, and location of the game,
(3) level of game (AA, AAA, Majors, Intermediate, Juniors), and
(4) your position (plate or bases).
The meal allowance for AA, AAA, or Majors games is $25 for bases and $30 for plate. The meal allowance for Intermediate, Juniors, or Seniors games is $35 for bases and $40 for plate. Checks are written once a month.
The meal allowance is available for NOLL/SOLL regular season, league playoffs, fall season, Tournament of Champions, and All-Stars.

Junior Umpires must be at least 12 years old and no older than 17. Junior Umpires can work games up to the level below the one they are playing, or eligible to play. For example: a Junior Umpire who is playing Majors may umpire AA and AAA games. Junior umpires may be base umpires on big diamond games (Intermediate, Junior, or Senior games) if they have at least one year of umpiring experience and have attended the field mechanics clinic.




AA will once again phase in stealing. Here is the modified stealing rule in effect in AA for the first three weeks of the season:
Week 1 = no steals.
Week 2 = Stealing second only. No advancing on overthrows from catcher to second.
Week 3 = Stealing second and third only. No advancing on overthrows from catcher to second or third.
Week 4 – end of season = No restrictions on stealing

As a reminder: In Majors and below, it is no longer necessary for the pitcher to throw pitches if the coach wants the batter walked intentionally. The coach must make this known to the umpire before any pitches are thrown to the batter; the ball is dead and four pitches are added to the pitch count.

Rule 1.10 (BATS): Beginning in 2018, there were significant changes in Rule 1.10. BPF 1.15 bats are now prohibited at all levels. The maximum bat diameter at all levels is now 2-5/8 inches. Use of pine tar or similar adhesive substances is prohibited. For Majors and below, all non-wood bats must bear the USA Baseball logo, signifying that the bat meets USA Baseball’s Youth Bat Performance Standard. For Intermediate Division and Junior League, all non-wood bats must either bear the USA Baseball logo or the BBCOR (batted ball coefficient of restitution) certification mark. For Senior League, non-wood bats must bear the BBCOR certification mark and bats may not exceed in inches by more than three their weight in ounces (for example, a 33-inch bat shall not weigh less than 30 ounces). At the Intermediate Division level and above, aluminum/alloy and composite bats shall be marked as being aluminum/alloy or composite. This requirement applies only to bats that have aluminum/alloy or composite barrels. The BBCOR and bat material markings shall be permanent, whether by silkscreen or otherwise, a minimum of one-half inch on each side, and located on the barrel of the bat in any contrasting color.
REGULATION VI NOTE 3 – PITCHERS and RULE 4.10(D) – All suspended games will be resumed from where they were stopped, regardless of when. Pitching records, including number of pitches, will be counted for that day and days of rest.
RULES 8.06(a) and (b) VISITS TO THE MOUND: A manager may come out twice in an inning to visit the pitcher, but on the second visit, the pitcher must be removed. A manager may come out three times in a game to visit a pitcher, but on the third visit, the pitcher must be removed. Majors and above only.

NOLL/SOLL Local Playing Rules for AA thru Seniors
We have local rules that supplement or alter what is in the official Little League rule book. These local rules are set forth in the Umpire Manual and on the NOLL/SOLL website. They do not apply to Inter-league games. Also mentioned are those instances where we have not adopted an optional Little League rule. All Little League Baseball rules are in effect, except as described below. In a couple of cases below, we have returned to the official Little League rule and that is mentioned for clarity.

· REGULATION VII(D) – PITCHERS: In AA and AAA, no pitcher may pitch more than nine defensive outs in a game. This will not apply in the regular season tournament. This rule is not a Little League rule.
· Rule 1.01, 4.17 (note) (Number of Players): In all divisions, a team may play with eight players. There is no penalty for playing one player short. If the team drops below eight players, there is no forfeit; the game is suspended and referred to the board for a decision. Little League rules do not allow for playing with less than nine players and a waiver has been APPROVED.
· Rule 1.10 (Field Dimensions): For Juniors, we use 60’ (distance to the pitcher’s plate) and 90’ (distance between bases). We have not adopted the Little League optional dimensions of 54’/80’.
· Rule 3.03 (Substitutions): The NOLL/SOLL local rule in this section has been replaced by the Little League rule as follows:
A substitute who enters for a starter can be replaced in the lineup, but both starters and substitutes can only enter in the same place in the batting order. A starter can re-enter but only in their original spot in the lineup and only after the substitute has met MPR. Once both starter and substitute have met MPR, they can re-enter freely in that lineup spot. Note that a starter does not have to meet MPR before being replaced but, once the starter re-enters the game, the starter will have to be in the game for six continuous defensive outs and one at-bat (if the starter did not get that at-bat while they were in the game the first time).
· Rule 4.04 (Batting Order and Substitutions): Continuous Batting Order (CBO) is in effect in AA thru Juniors.
· Rule 4.10(e) (Ending a Game): In all divisions, a game will end if one team is ahead by 15 or more runs after 3 innings (4 innings for Intermediate and higher); or if a legal game (4 innings in Majors and below, 5 innings in Intermediate and above), the game ends if one team is ahead by 10 or more runs. If the home team is ahead by 10 or more runs, game ends after 3 ½ innings (Majors and below) or 4 ½ innings (Intermediate and above).
· Rule 6.02(c) (Batter Keeping One Foot In Batter’s Box): We have not adopted the optional Little League rule requiring the batter to keep one foot in the batter’s box at all times during their at-bat with several noted exceptions.
· Rule 6.05(b)2 (Uncaught 3rd Strike): The batter advancing on an uncaught 3rd strike rule is in effect in Majors and above. We have not adopted the Little League option to have it not apply in Majors.
· Rule 7.14 (Special Pinch Runner): We have adopted the Little League option to apply this rule during the regular season. It is only in effect in games that are not using CBO.
· Rule 9.01(d) (Stealing Signs): We have not adopted this Little League optional rule to eject players and/or managers caught stealing pitch selection or location signs.
· Time Limit (No Rule): In AAA and lower, no new inning may start once the game has reached 1 hour & 50 minutes in length. In Intermediate and above, no new inning may start once the game has reached 2 hours & 15 minutes in length. The game ends immediately if the time limit is reached in the bottom of an inning with the home team ahead, if a legal game. There is no time limit in Majors games. There are no Little League rules regarding time limits.


Google Group

We have a discussion forum for talking about rules and other issues and finding game assignment replacements. In order to join, go to NOLL/SOLL Little League Umpires Google Group and ask to join the group. All NOLL/SOLL umpires are encouraged to join. Note: This forum does not replace the Sportability game scheduling and assignment website for requesting game assignments.



Q: I was assigned to a game that I cannot umpire. How do I find a replacement?
A: If you cannot make one of your assignments, please notify the appropriate umpire coordinator ASAP so you can be removed from the game. You can also post a request in the Yahoo Groups discussion forum.
Q: I ejected someone from a game I umpired. What should I do now?
A: If for any reason you ejected a player, manager, or any other person from a game, you are required by Rule 9.05 to report it to the Chief Umpires, who will then forward it to the NOLL/SOLL President. Explain the circumstances of the ejection, including the name of the person ejected. Timely reports are critical; please send your report within 24 hours of the incident. Read Rule 9.05 for the information you are required to include in the report. League officials will notify the coordinators of the appropriate level to ensure that the person(s) ejected are not permitted to participate in the next game, in accordance with Little League rules.
Q: Equipment was missing from the umpire equipment bag at the field. What should I do?
A: Never umpire a game behind the plate without wearing a complete set of protective equipment, including mask, chest protector, leg guards, and a hard cup for males. You can call balls and strikes from behind the pitching mound if protective equipment isn’t available. After the game, e-mail the umpire equipment coordinator so he can arrange for the replacement of missing equipment.
Q: How should I report abusive or inappropriate behavior in a game I umpired?
A: The league wants to know the circumstances of abusive or inappropriate behavior by anyone at our games. Rule 9.05 requires umpires to report to the League President, any “incidents worthy of comment.” Submit your report to  the Chief Umpires and they will forward it to the League President.
Q: I have a question about a rule or a situation which came up in a game. Whom can I contact?
A: First look at the Little League rule book. You can also contact the Umpire Coordinator at the level of play to which the question relates or the Chief Umpire. Our Google Groups discussion forum is also an excellent place to post questions and comments about rules and situations. NEVER REFER TO THE RULE BOOK DURING A GAME!
Q: A manager wants to protest a game I am umpiring. What do I do?
A: Protests are rare, but they can occur and may be legal. Protests may be based on rule interpretations (Rule 4.19). Protests cannot be based on judgment calls. Protests must be made by the manager before any succeeding play (e.g., before the next pitch, or pick-off attempt, etc.). The manager notifies the umpire that the game is being played under protest and informs the umpire of the basis for the protest. At that point, all umpires confer and decide whether the rule interpretation was correct. If the rule interpretation was incorrect, change the decision. If the rule interpretation was correct (or was a matter of judgment which cannot be protested, or the protest is untimely) inform the manager that the decision stands. Then have the official (visitors) scorekeeper record the exact game situation at the time of the protest in the scorebook. Have the protesting manager state the basis for the protest in his own words and have those words written in the scorebook. The game then continues to conclusion. The crew chief must “immediately” notify the Chief Umpires of the protest and the rationale for denying the protest, in writing.
