Next scheduled game Tuesday, August 27th.

Start Spreading the Rules

General Guidelines

ALL Parks - Melas Park, Schaumburg and Rosemont

Gates/doors are typically open at 8:30AM. Please show up for batting practice from 9:00AM thru 9:45AM as games start at 10:00AM. Lineups are fairly established between 9:45AM and 9:55AM. If you are not signed in by that time it creates lineup decisions that impact everyone and often delay game starts. If circumstances delay your arrival until after 9:45AM, please be considerate and contact a fellow ballplayer and ask him to sign you in (advise how late you will be). Failure to sign in (or be signed in) by 9:45AM will result in you being slotted as the last batter, as a rover and/or even assigned to a diamond other than your usual diamond. 

Arlington Heights wants us to remind all that alcohol is prohibited on their premises - including parking lot.


The Rules


  • Games are generally 7 innings in length. Exceptions are made for different circumstances where they are 9 innings. If 7 innings a double header is usually played. If 9 innings, one game is played.


  • The maximum number of runs allowed per inning is four with the exception of the last inning  in which runs are unlimited. 


  •  The pitcher’s zone is two feet wide with quick access to pitching screen. The ball must be slowpitched, and the arc of the ball must be between six and twelve feet. The pitcher must keep at least one foot on the pitching rubber (at Melas Park it is the closer of the 2 painted pitching rubbers) until the ball is released. Hesitation moves are not permitted. Spinning or knuckling is permitted. 
  • The pitching screen is employed to protect the pitcher - not as an extra fielder. To ensure pitcher protection the screen must be positioned so that at least some part of the base of the screen touches or is in line with the pitching rubber, not to exceed 3 feet in front of pitching rubber.
  •  We use a wood strike zone mat that includes home plate. A legal pitch that hits any part of the strike zone mat is a strike. 
  •  If a pitch is illegal, the umpire will call “illegal” before the pitch crosses the plate. The batter may swing at an illegal pitch. If there is no swing, the pitch is called a ball. 
  •  Pitchers are encouraged to wear a face mask. 

Base Running 

  • All player safety is of paramount importance. With that in mind:
  •  A base runner must do everything possible to avoid colliding with a fielder. If the runner makes little or no effort to avoid colliding with a fielder, the umpire will call the runner out, the play will be called dead, and all runners will return to the last occupied base. If it happens a second time in a game, the player may be ejected. 
  •  Home plate to first base: If a play is contested at first base, the batter must use the safety base located in foul territory next to the regular first base. If there is no play at first base, the batter may use the regular first base. Violation of this rule is an out unless the batter did so to avoid colliding with the first baseman (for example, the first baseman is off first base fielding a ball and blocks the batter’s path to first base.)
  • First base to second base to third base: The runner may overrun second or third base in a straight line and return to the overrun base. The runner does not have to touch second or third base when overrunning the base. Force-outs at second and third base are determined by whether the fielder catches the ball before the runner reaches the base. Runners must run to the non-fielder side of the base to avoid interfering with the fielder. When overrunning second or third base, the runner must return to the overrun base before advancing to the next base. If the runner does not return, the runner is in play and may be called out. The runner cannot be called for interfering with a fielder’s throw as long as the runner is in the three foot wide base lane and does not raise hands to make contact with the ball.  
  • All bases: With the intent to avoid injuries, plays at all bases are treated as force-outs; a runner can be tagged out between bases. For safety, there is a second home plate adjacent to the regular home plate. Runners step on the second base to run through the base at first base and run wide at second and third. A runner scores by stepping on the second home plate. The wood strike zone mat is for the catcher, who may step on any part of the strike zone mat to force out the runner. If a runner steps on any part of the strike zone mat, he is out.  
  • A marker placed perpendicular to the third base line and twenty feet from home plate is the commitment line. Once a runner crosses this line, he must continue to home plate. Violation of this rule is an out. 
  • Sliding and diving are not allowed. A runner who slides or dives will be called out - an exception is allowed if the slide or dive is made solely to avoid injury/contact. 
  • If a runner continues to play on after making a turn toward or taking a few steps toward the next base, he may be tagged out. When returning to a base, a runner may not overrun the base. 
  •  A base runner cannot leave his base until the batter makes contact with the ball. Leaving a base early is an out. There is no rule violation if a runner leaves the base when the ball crosses home plate and is not hit.  
  • Metal cleats are not permitted. 


  • A legal bat is an official softball bat that is no more than 34” in length, no more than 38 oz. in weight, and no greater than 2.25” in diameter at its largest part. If a player is discovered using a bat that exceeds these dimensions, the umpire will instruct him to remove the bat from play. If a player violates the rule a second time, he will be ejected from the game, and his at bat will be ruled a strike out. 
  •  High performance and/or altered bats at not permitted in games or in batting practice.  Single wall and composite aluminum bats or wood bats are permitted.  
  • There is no marked batter’s box. A reasonable area will be considered the batter’s box. A batter will be called out if he steps on the strike zone mat when hitting a pitch, whether it is hit fair or foul, or if all of his back foot is completely in front of the strike zone mat when he hits the pitch.  
  • Each batter begins with a 0-1 count, no balls and one strike. (An exception is made for a game with three teams where the count starts 1-1.) The batter is out on any third strike. This includes a foul ball after two strikes.  
  • A batter must take a full swing at a pitch. Bunting or chopping is an out.  
  • A batter who hits a ground or fly ball into the outfield is automatically awarded first base (unless the fly ball is caught). Rovers are considered as outfielders.  
  • If a batter hits a foul ball and the catcher catches it, the batter is out.  
  • If a batter throws or releases a bat and it hits another player or the umpire, the player is out. If the batter throws a bat and it does not hit anyone, the player will receive a warning; a second occurrence in a game is an automatic out. A player throwing a bat in anger may be ejected from a game, and his at bat in the lineup will count as an out. 

Live and Dead Balls 

  •  If an overthrown ball hits the fence and remains on the field, the ball remains live and in play.  
  • If an overthrown ball hits any dugout equipment or goes out of play, the ball is dead and the runners take their appropriate bases: two bases from where they were at the time of the thrown ball’s release.  
  • If an overthrown ball hits a coach on the offensive team, the ball is dead and no extra bases are awarded.
