1. Pitching Rules (Modified Fast-Pitch “Chata”)

1.1. The official pitching style for this league is Modified Fast-Pitch (“Chata”). All pitchers must deliver the ball using a controlled, legal underhand motion consistent with modified standards.

​

1.2. The delivery must follow a legal Modified (“Chata”) motion, as determined by the umpire. A legal pitch may include a natural hump, as long as it remains within modified legal limits.

​

1.3. Windmill, Sling, Arc, and Sidearm deliveries are strictly prohibited. Any motion that violates Modified (“Chata”) standards will be ruled illegal.

​

1.4. Pitchers may begin with either: Both feet in contact with the pitching rubber, or One foot on the rubber and the other positioned behind, stepping forward during release.

​

1.5. Pitch speed is not restricted, provided the motion remains within the legal Modified (“Chata”) form.

​

1.6. A legal pitch must cross the strike zone to be called a strike. Any illegal delivery will be declared a ball, unless the batter swings.

​

1.7. The umpire has full authority to determine whether a delivery meets the Modified (“Chata”) legal standard. Repeated illegal motions may result in warnings, pitcher replacement, or other league penalties.

When the lineup is given to the umpire, all listed players must be physically on the field. If a listed player is not present, she must be removed immediately.

​

9.3. Mandatory Participation in Doubleheaders

During the regular season, each player must participate in at least one full 6-inning game in a doubleheader, only if present for both games. Players present for only one game: The manager is required to play them only 3 defensive innings in that game. The manager will not be penalized if the player only plays 3 innings. Players present for both games: Minimum participation of 6 innings applies, distributed at the manager’s discretion (for example: 2 and 4 innings, 1 and 5 innings, or 3 and 3 innings).

​

9.4. Clarification of Participation (Updated) There was previously a rule stating that every player must play 6 innings. Some players expressed concern that if they were only batting, they were not considered as 'playing.' CORRECTION: Batting, serving as an EH/DH, or running for a teammate DOES count as participation, even if the player is not defensively on the field. This is a TEAM SPORT, and all roles contribute to the game. Managers must now follow the adjustment below:

• Every player must play at least 3 defensive innings on the field.

• Every player must participate in at least 6 total innings within 2 games. If a player only attends the 2nd game of a doubleheader, the manager is required to play her only 3 defensive innings in that game. Every player will have the opportunity to participate — whether fielding, batting (EH/DH), or running for a teammate. Managers may use their discretion to ensure this rule is met fairly and in good faith
