Rules for the game you are working

These are CSYBA games, not Little League games. Little League rules are not the rulebook here, and they are not the rulebook in any division Alsip is playing this fall. Check the division you are working before you take the field.

8u

PeeWee, CSYBA B Division

RulebookNot stated. The CSYBA 8u document names no base rulebook at all, so anything not in the list below is unsettled.

Game
6 innings. No new inning after 1 hour 45 minutes.
Runs
5 per inning. There is no slaughter rule.
Official game
4 innings, or 3 1/2 if the home team is ahead.
Field
60 foot bases, 40 foot mound.
Pitching
Kid-pitch in innings 3 and 4 only. One inning per pitcher; one pitch counts as a full inning. A pitcher who hits 3 batters is removed from pitching.
Bats
USA Baseball or USSSA stamp. Wood is fine.
Team
6 players minimum. No substitutes and no borrowed players.
Fielding
10 fielders allowed. If 10, four must be outfielders.

Different from Little League

  • Innings 1, 2, 5 and 6 are coach-pitch; 3 and 4 are kid-pitch. In the fall a team may decline to pitch, so ask both coaches before the game which it is.
  • There are no walks at all. Coach-pitch is 6 pitches and then the batter is out, unless the last one is a foul. In kid-pitch, 4 balls brings the coach in for 3 more pitches.
  • A batter hit by a kid's pitch chooses first base or carrying on with the at-bat. Hit by a coach's pitch, there is no base.
  • No bunting.
  • On a ball that stays in the infield the batter gets first only, and every other runner gets one base. No extra base on an overthrow, even out of play.
  • On a ball that reaches the outfield grass, play stops once a player controls it in the pitcher's circle. A runner two thirds of the way gets the base, less than two thirds goes back.
  • Bat thrown once is a warning. Thrown twice, the batter is out.
  • You may call balls and strikes from behind the mound or from behind the plate.
  • USSSA and BPF 1.15 bats are legal here. Little League Rule 1.10 prohibits them and caps the barrel at 2 5/8 inches.
  • Six players is a game. Little League Rule 4.17 will not continue one below nine, or eight by local option.

11u

Minors and Majors, CSYBA A Division

RulebookThe Official Rules of Major League Baseball cover anything the CSYBA local rules do not.

Game
7 innings. No new inning after 2 hours. If it is tied when time expires, it stays a tie.
Runs
No limit. 12 ahead after 4 innings ends it, or 10 after 5.
Official game
4 innings.
Field
70 foot bases. Pitching 48 to 50 feet, set by the home community.
Pitching
3 innings per pitcher; one pitch counts as a full inning. Balks are called with one warning. 3 hit batters and the pitcher is removed. A second mound visit in an inning also removes the pitcher.
Bats
USA Baseball, USSSA 1.15 BPF or BBCOR. Barrel up to 2 3/4 inches.
Team
Continuous batting order, everybody bats. Free substitution in the field except the pitcher.
Gear
Rubber spikes or gym shoes only. No player in a soft or hard cast may play, no exceptions.

Different from Little League

  • Leadoffs and stealing are allowed. Little League Rule 7.13 keeps runners on the base until the pitch reaches the batter. This is the one most likely to cost you an inning.
  • Infield fly and dropped third strike are both in effect. Kill play is not, at 11u and 12u.
  • Balks are called here, with one warning. Little League Rule 2.00 says a balk is not called at Major Division and below.
  • There is an on-deck batter. Little League Rule 1.00 does not permit an on-deck position at Major Division and below.
  • Pitching is capped in innings, not pitches, and no pitch count is kept. Little League Regulation VI caps 11 and 12 year olds at 85 pitches a day with required rest days.
  • USSSA and BPF 1.15 bats are legal, with barrels to 2 3/4 inches. Little League Rule 1.10 prohibits BPF 1.15 and caps the barrel at 2 5/8 inches.
  • Courtesy runner is for the catcher only, with two outs, and it must be the player who made the last out.
  • A fake bunt followed by a full swing is an out, and runners hold.
  • A runner is out for failing to slide or failing to avoid a fielder holding the ball. A fielder may not block the path without it.
  • Forfeits are yours to declare: a no-show, no 9 rostered players within 10 minutes of the start, a cancellation inside 24 hours, or an ejected person who will not leave. A forfeit is recorded 7-0.
  • On an ejection, name the person to the manager. They then have 5 minutes to get out of your field of vision or the game is forfeited.

14u

Juniors, CSYBA B Division

RulebookNational Federation of State High School Associations (NFHS) rules, the same book as IHSA high school ball, supplemented by the CSYBA local rules.

Game
7 innings. No new inning after 2 hours 15 minutes. Extra innings if time allows.
Runs
No limit, though both managers may agree on a 7 run cap before the game. 10 ahead after 5 innings ends it.
Official game
5 innings, or 4 1/2 if the home team is ahead.
Field
80 foot bases, 54 foot mound.
Pitching
In the fall, 4 innings per game AND 4 innings total across a three-day weekend. One pitch counts as a full inning. The league keeps no pitch count.
Hit batters
3 and the pitcher is removed. You may waive this if the batter could or should have moved.
Bats
USA Baseball, USSSA or BBCOR.
Team
7 players minimum. Continuous batting order, late arrivals bat last, a player who leaves is scratched with no penalty.
Playing time
Every player present fields 4 complete innings, 3 of them before the 6th starts.

Different from Little League

  • The rulebook is NFHS high school ball, not Little League.
  • Leadoffs and stealing at every base. Head-first slides are allowed. Little League Rule 7.08 makes sliding head first while advancing an out at Major Division and below.
  • Intentionally initiating contact at a base is an out, in your judgment.
  • Slash bunting is banned. Squaring, pulling back, then swinging is a dead ball and the batter is out.
  • Bat thrown once is a warning. Thrown twice, the batter is out.
  • A pitcher taken off the mound may not return to it. A reliever coming in cold gets at least 7 warm-up pitches.
  • USSSA and BPF 1.15 bats are legal. Little League Rule 1.10 prohibits them.
  • Seven players is a game. Little League Rule 4.17 will not continue one below nine, or eight by local option.

16u and 18u

Seniors, CSYBA high school divisions

RulebookNational Federation of State High School Associations (NFHS) rules, the same book as IHSA high school ball, supplemented by the CSYBA local rules.

Game
7 innings. No new inning after 2 hours 15 minutes. Extra innings if time allows.
Runs
15 ahead after 4 innings ends it, or 10 after 5.
Official game
5 innings, or 4 1/2 if the home team is ahead.
Field
90 foot bases, 60 feet 6 inches pitching.
Pitching
7 innings per pitcher per game. One pitch counts as a full inning. The league keeps no pitch count.
Hit batters
3 and the pitcher is removed. You may waive this if the batter could or should have moved.
Bats
BBCOR or wood only. USA stamped bats are allowed in the fall for incoming freshmen.
Team
7 players minimum. Teams may borrow a player in the regular season.

Different from Little League

  • The rulebook is NFHS high school ball, not Little League.
  • Metal spikes are allowed, but never on turf. Local park rules win.
  • Nobody has to slide, and a head-first slide into home is legal. Little League Rule 7.08 makes sliding head first while advancing an out at Major Division and below.
  • Slash bunting is banned. Squaring, pulling back, then swinging is a dead ball and the batter is out.
  • Bat thrown once is a warning. Thrown twice, the batter is out.
  • A pitcher taken off the mound may not return to it. A reliever coming in cold gets at least 7 warm-up pitches.
  • The batting order and the fielding lineup are independent, so a player can pitch or field without batting at all.
  • Pitching is capped in innings, not pitches, and no pitch count is kept.
  • Seven players is a game. Little League Rule 4.17 will not continue one below nine, or eight by local option.

Before every game

  • Take two new game balls from the home team. That is their job at 8u, 14u, 16u and 18u.
  • Go over the ground rules with both managers. At 11u the CSYBA rules require it, and it is worth doing everywhere.
  • At 8u, ask both coaches whether they are doing kid-pitch innings today. In the fall a team is allowed to decline, and then it is coach-pitch throughout.
  • Note the time you actually start. Every division ends on a time limit and the clock is yours to keep.

Good to know

  • Under Alsip's bylaws, umpires are appointed by the President or Umpire in Chief with the approval of the Board.
  • Once someone has signed up for a game, nobody else can take it from the page. If a game needs to change hands, contact the Umpire in Chief.
  • We identify you by your mobile number, so use the same one every time. If you use a different number we have no way to tell it is still you, and the page will treat you as somebody else.
  • You can cancel your own sign-up from this page using the number you signed up with. To fix a typo in your name, cancel and sign up again.
  • Once the league has confirmed a crew, the page stops letting anyone change it. Contact the Umpire in Chief instead.

What we do with your details

Alsip Little League collects your name and phone number so we can staff umpire slots for this season.

Your name is public on this page so other umpires can see which games are covered. Your phone number is not shown here and is not public. Board members can see it so someone can reach you about a game.

We only keep your name and number for future games if you tick the box on the form. Leave it alone and we use your details for this game only.

Sign-ups and changes are recorded and are visible to the board.

To have your information removed, email baseball@alsiplittleleague.org. Removal clears your name and number from our list. It cannot reach copies already sent in an email.

Not settled yet

Games come from the CSYBA published team schedules for Alsip's five entered teams. That scrape is unofficial. Re-check the posted schedule before each weekend, because CSYBA can move games.
Umpire counts follow the June 13 Board Record, which raised only the high school fee because high school fall ball uses two umpires per game.
Who makes the rain-out call is not settled on the league record and has not been guessed here.
The division rules above are summarized from the CSYBA division documents dated August 15 to August 18, 2026. They are a summary and not the rule book. Where a summary and the CSYBA document disagree, the CSYBA document wins. Check the current published version before a game.
