The League is organized, conducted and administered by a volunteer staff with expertise in Softball , on which our Fastpitch variation is based. These volunteers make up an Executive Board which will govern the implementation and execution of our league strategy. The key distinction between the league as it is being run and other leagues currently available is in the rules format which exists, the absence of team registration, and the openly competitive nature of the games; most notably the changes from the slow-pitch variation of softball to a fastpitch variation.

4.0 Miscellaneous & Other Important Things

4.1 Dropped 3rd Strike: On an uncaught third strike with
(1) no runner on first base, or
(2) with a runner on first base and two outs, the batter immediately becomes a runner. The strike is called, but the umpire does not call the batter out. The batter may then attempt to reach first base and must be tagged or forced out. An “uncaught” strike includes not only pitches dropped by the catcher, but also pitches that hit the ground before the catcher attempts to catch it

4.2 Infield Fly: A fair fly ball (not including a line drive or an attempted bunt) that can be caught by an infielder with ordinary effort when first and second, or first, second, and third bases are occupied before two are out. The pitcher, catcher, and any outfielder who positions themselves in the infield on the play will be considered infielders for the purpose of this rule.
(a) On an infield fly the umpire shall identify it immediately by calling out “Infield Fly, Batter is out, IF fair.
(b) Other base-runners may advance at their own discretion.

4.3 Strike zone: The space over any part of home plate between the batter’s armpits and the bottom of the batter’s knee cap, when they assume their natural batting stance. The natural batting stance is the stance the batter takes after the release of the pitch when deciding to swing or not swing at the pitch.

 4.4 Interference: On a batted ball, the first defensive player to play the ball has right of way over a base-runner/batter-runner.

Also, the runner is not out when more than one fielder attempts to field a batted ball and the runner comes in contact with the one who, in the umpire’s judgment, was not entitled to field the ball.
Note: Contact does not have to occur for interference to have occurred. Any action by a base-runner/batter-runner that negatively affects the defender’s ability to field a batted ball is considered interference.

4.5 Obstruction: On a thrown ball, a base-runner/batter-runner has the right of way over any defender attempting to catch a thrown ball.

4.6 Obstruction: Fake Tag: A fake tag (an attempt to tag a runner/batter-runner while not in possession of the ball) is obstruction. Note: Contact does not always mean interference or obstruction occurred. There is such a thing as incidental contact - 2 players both unsure of where to go and contact is made.

4.7 Overrunning First Base: The batter runner may turn in any direction after overrunning first base as long as they return to the base immediately. If an attempt is made to go to second base, the runner can be tagged out. This is a judgment made by the umpire.

4.8 Strike: A strike is an attempt to hit the ball. Simply holding the bat over the plate is not an attempt. A bunt is a batted ball not swung at, but INTENTIONALLY met with the bat and tapped slowly. If no attempt is made to make contact with the ball outside the strike zone, it should be called a ball.

4.9 Bunting: Permitted

4.10 Slap Hit/Slap Bunt: A slap hit/slap bunt is not a bunt. With 2 strikes, a slap hit/slap bunt going foul is not considered strike 3.

4.11 Check swing: If it is the plate umpire’s judgment that the batter made an attempt to swing at appealed to the base umpire - use the guiding principle that the plate umpire does not call it a strike unless they see the attempted swing - therefore no need for an appeal of what the plate umpire saw.

4.12 Safety Bag - On any live ball play made from first base foul territory, the batter runner and the defensive player may use either base.
(a) When the defensive player uses the foul portion of the double base, the batter-runner can run in fair territory and if hit by a throw from the foul side of first base, it would not be interference.

 (b) If the fielder uses the orange base in this situation and the runner makes contact with the fielder it is interference on the runner. If both players use the white portion and the fielder causes the runner to hold up or change direction it is obstruction on the fielder.

4.13 Thrown ball goes out of play:
(a) all runners, including the batter-runner shall be awarded two bases from the last base legally touched based on their position at the time that the thrown ball left the fielder’s hand.
(b) if there are two runners between the same bases, the award is based on the position of the lead runner.

4.14 Fair ball bouncing out of play or off a defensive player.
(a) When a fair ball bounces out of play, including if it deflects off a defensive player, the umpire shall declare “Dead Ball” as soon as the ball goes out of play.
(b) All runners shall be awarded two bases.
(c) The award is based on their position at the time of the pitch - not at the time that the ball went out of play.
(d) The award is the same regardless of where the ball actually goes out of play.

4.15 Lead-off (Pitcher’s Circle)
(a) The common misconception is that if the ball is thrown back to the pitcher and they have it in their position in the pitcher’s circle before the batter-runner reaches first base that the batter-runner must stop at first base.
(b) Even though the ball may be in the pitcher’s possession in the pitcher’s circle, the batter-runner may:
1. continue past first base.
2. is entitled to run toward second base, as long as they don’t not stop at first base.
3. Once the runner makes a stop, they must immediately proceed to the next base or return to their base UNLESS the pitcher makes a play (including a fake throw) on the runner or another runner.
(c) The RUNNER is OUT IF: the runner stops and simply stands there off the base while the pitcher has possession of the ball in the pitcher’s circle and no play is made - “DEAD BALL - RUNNER IS OUT - LEAD-OFF” If the runner stops and then makes a move in more than one direction immediately after the stop while the pitcher has possession of the ball in the pitcher’s circle and no play is made “DEAD BALL - RUNNER IS OUT - LEAD-OFF”
(d) Points of Emphasis: The pitcher cannot force the first stop by a runner merely by having possession of the ball in the pitcher’s circle. Put another way - the runner is allowed one stop - as soon as they stop they must make a decision immediately to either advance or return.
(e) A play on the runner (including a fake throw) nullifies any penalty - put another way, every fake throw allows the runner one more stop.

4.16 Courtesy Runner:
(a) Allowed, and shall be the last out, or if no one has been declared out, the player furthest from coming to bat (and is not on base).
(b) Courtesy runners are not permitted to steal bases nor advance on a passed ball. Unless a fielder attempts to make a play at that base.

4.17 Playing equity Rules: During the regular season

(a) Outfielders may not set up any closer than 20 feet from the infield skin.
(b) Infielders may not set up closer to home plate closer than the pitching rubber.

4.18 Optional base running on home run:
(a) While all players are encouraged to run all bases after hitting a home run, if a player wishes not to run the bases, it is not required for the runs to count.

(a) At the start of the pitch, one (1) foot is required to be on (touching) the rubber (Drive leg).
(b) The other foot (stride leg) may be behind the rubber.
(c) Prior to delivering a pitch there MUST be a pause (Entire Body Motionless) with both hands together in front of the body for a minimum of 2 to a maximum of 5 seconds.
(d) The next motion constitutes the start of the pitch, (once the hands separate they may not come together again),

(e) The drive leg foot must remain in contact with the pitcher’s plate prior to the start of the pitch. Lifting the pivot foot off the pitcher’s plate and returning it to the plate, creating a rocking motion is an illegal act. This foot must stay in contact with the ground. Dragging is ok. Replanting is not 
(f) Leaping and crow hopping are not permitted
(g) The Pitcher MUST immediately deliver the ball to the batter and all movement from this point shall be forward. It is illegal to step behind the rubber AFTER the pause. EXCEPTION: IF the Pitcher wishes to call time they must step off to the rear of the rubber first, and call for “Time”.
(h)  Ball must be released prior to loss of contact with the pitching plate.

(i) The delivery must be an underhand motion, with the hand below the hip, the wrist not further from the body than the elbow and with no stop or reversal of the forward motion.
(j) Windmill pitching is prohibited.
(k) Pitchers MUST deliver the pitch in an underhand motion.
(l) Pitchers arm may not be extended above the shoulder, the ball remaining  around the head on the the backswing.   Arm  may not extend vertically above the head.
