Juniors Baseball Rules


  • Field Dimensions:  Games typically on diamonds with 60’6" pitching rubber and 90’ bases, but some games (especially earlier in the year) may be played on fields with slightly shorter dimensions to ease the transition to the 60/90 diamond for players.  Games will be 6 innings in length or time limits specified by the League.  In the event of inclement weather, a game is complete if 4 innings have been completed or if the home team is winning after 3½ innings.  If a game is tied following the end of the last inning, the game is recorded as a tie.  Games must start no later than 15 minutes past their scheduled start time.
  • Batting:  All players present at a game will bat in the batting order.  This allows for free substitution on defense (except pitching).  If a player is injured or becomes ill after the game begins, spot in the line-up becomes dead and no out(s) are recorded when that player's spot comes up.  Injured/ill players are not typically allowed to re-enter, but may do so with mutual agreement by both coaches, re-entry in same place in batting order.
  • On-Deck Batters/Equipment:  Only the first batter of each half-inning will be permitted outside the dugout between half-innings.  One on-deck hitter is permitted otherwise, as well.
  • Pitching:  Pitcher is allowed to pitch 3 innings per game with 1 pitch considered an inning.  Once a pitcher is removed from pitching, player is not allowed to re-enter as pitcher.  Balk rule is in effect; each team issued a warning before a runner can advance.
  • Warming Up Pitchers:  Players warming up pitchers are required to wear a mask.  If you are warming up a pitcher not currently in the game, please have a player with a helmet on protecting the bullpen pitcher and catcher from a batted ball, or have an adult age 18+ providing such protection.  League exception:  Coaches warming up pitchers do not have a mask requirement -- any such coaches must be at least age 18.
  • Catching Equipment/Mitt:  League exception:  Catchers do not have a catcher's mitt requirement, though it is suggested.  A glove of any shape, size, or weight, consistent with protecting the hand, is acceptable.  All catching masks worn must meet accepted safety standards.
  • Baseball Cleats:  Any/All types of baseball cleats are allowed.  Note that the portable mound used at Sacred Hearts may be slippery if metal cleats are used on it, so plastic should be considered for Sacred Hearts.
  • Umpires:  League provides paid umpires.  Balls/strikes called from behind catcher. Umpires will bring game balls, and each team then may keep one after the game for practice, we ask those go back in the bags at end of year.
  • Base Running:  The base runner has the right-of-way within the base paths (3’ either side).  Runner is awarded the base he is headed for if obstructed, unless fielder is playing the base or fielding the ball.  If runner obstructs a fielder who is playing the base or fielding the ball, runner is out.  Leading off is allowed.  Runner must slide if a play is being made on him.  Failure to slide results in an out and possible ejection.  Head-first sliding is allowed.
  • Courtesy Runners:  Allowed for catcher if reaches base or is on base when out #2 is recorded.  If any other player is injured during the game, courtesy runner may be used.  Player who made last out is the courtesy runner.
  • Stealing:  Unlimited stealing is allowed. Discretion & sportsmanship is encouraged in games.
  • Bunting:  No limitations on bunting.  Again, discretion & sportsmanship is encouraged in games.
  • Run Rule:  There is a 10 run rule after 4 innings completed.  If the visiting team is leading by 10 or more runs after the home team has batted in the 4th inning, the game is considered completed.  If the home team is ahead by 10 or more runs after the visitor has batted in the top of the 4th inning or is ahead by 10 or more runs after batting in the 4th inning the game is considered completed. 
  • Infield Fly Rule Applies:  If runners on 1st & 2nd or bases are loaded with less than 2 outs, and batter hits a fair fly ball (not a line drive or bunt) that could be caught with ordinary effort by a defensive player stationed in the infield, Infield Fly should be called.  Is the fielder comfortable under the ball?  If so, you’ve got “ordinary effort.”  As soon as umpires says “Infield Fly”, batter is out and force is removed from runners.  Runners do not have to run if umpire says "Infield Fly."  Runners are subject to rules regarding tagging up – if ball is caught, they must tag up before they advance.  But if ball is not caught, they do not have to tag.
  • 3rd Strike:  If the catcher does not catch the 3rd strike, the ball is live and the batter becomes a base runner (provided that 1st base is unoccupied; or if 1st base is occupied, there are 2 outs).  Other base runners can advance.
  • Interference:  If a batter interferes with the catcher’s throwing or fielding, batter is out and runners cannot advance.  If the catcher interferes with the batter, the batter is awarded 1st base.
  • Bat Size:  For the 2020 season, SPYBAS has decided to use the following guidelines for our baseball leagues:
    • 2 1/4” diameter bats that do not fit the 2018 USABat standards can be used at all levels, regardless of drop weight.
    • 2 5/8” diameter bats must meet the 2018 USABat standards and have the appropriate stamp of approval, regardless of drop weight.
    • 2 5/8” bats that fit BBCOR standards are allowed.
    • It is important to recognize that tournament teams will only be allowed to use bats that meet the new USABat standards during tournament play.
  • Sacred Hearts Field:  All balls hit into fair territory remain in play and live at all times (no dead ball applies if hit into brush or sloped area in deep center and right fields).

CHUMS Field:  All balls hit into fair territory remain in play and live at all times.
