3. Rosters must be presented to the opposing coach at the 1st scheduled game with that team. Players may be added to a

4. Final rosters must contain a minimum of (8) players and a maximum of (20).
5. No boys are permitted to play in the Marysville League games or tournaments.
• A player may steal 2nd and 3rd base only. A player may only steal (1) base at a time per pitched ball. No player is permitted to
steal while the coach is pitching. A batter hit while the coach is pitching will not be awarded first base. Home base may be
stolen ONLY if the catcher throws to anyone but the pitcher. No stealing ever on an overthrow to the pitcher.
• Bunting is permitted, except off of the coach pitching.
• A runner may advance (1) base only on an overthrow from a ball that is in play by an infield player. Advance at your own risk.
No additional bases will be granted on any additional overthrows per play.
• The batter is out on a dropped 3rd strike. The ball is live and the runners on 1st and 2nd may advance at their own risk.
• A maximum of two walks per innning per team will be in play for 2022. A batter cannot be walked after two walks are issued in the inning. After two walks are issued when the player throws the fourth ball to a batter, the coach comes in to pitch. The coach is then given up to 3 pitches to finish the count, regardless of the count. That means if the count is full, and the coach throws a pitch called by the umpire as not a strike, and the batter does not swing that the coach still has up to 2 more pitches. If the 2nd pitch is also not a strike, and the batter does not swing, then the coach has one more pitch. On that last pitch, the at bat is over regardless of the outcome unless the batter fouls that pitch off. If however in this situation with a full count from the player pitcher, the umpire calls a strike on the 1st or 2nd pitch, or the batter swings and misses on the 1st or 2nd pitch, then the at bat is over and an out is recorded. If there are no strikes on the batter, the coach still gets 3 pitches. It does not matter in this situation if they are balls or strikes; the coach pitcher is limited to 3 pitches. The coach must throw a flat pitch from the pitching rubber that is consistent in speed with the pitches thrown by the players in the league. Each illegal pitch will count as one of the 3 pitches for each batter. When the coach comes in to pitch, the player pitcher must have one foot inside the
8ft pitching circle. If the offensive coach is hit by, or inadvertently catches a batted ball, that ball will be called a foul ball.
• Runners may not leave their base until the ball crosses home plate.
• The 4 outfielders must be in a normal playing position. Depending on the size of the field it can be defined as the edge of the
grass or an approximation of 20 ft. beyond the base paths.
• If a player gets hurt on a batted ball, play stops and runner is awarded the next base.
