Mountain Home Recreational Youth Baseball Ground Rules
The following rules apply to ALL leagues.
Revised 2/4/2020 9:23 AM
ANY rule not specifically covered here or in the rules for each individual age group will be governed by USSSA.
- There will be no profanity, obscene gestures, or throwing of any equipment. This can result in automatic ejection from the game in which it occurs and suspension from the net game. The second time one of these violations occurs, the person or persons involved will meet with the Mountain Home Youth Baseball Board. At this meeting it will be decided if the person or persons involved will be allowed to continue in the Mountain Home Youth Baseball League.
- In case of a discussion, only the manager or head coach will speak to the chief umpire. All other coaches or players will either stay at their positions or in the dug-out. If this is violated, the person or persons involved may be ejected and suspended for one game. If it happens a second time, the person or persons involved will have to meet with the board where it will be decided if the party involved can remain in the Mountain Home Youth Baseball League.
- A player, coach, or a fan ejected from the game must leave the park.
- There will be no yelling of personal or personal pronoun names. There will be no banging of bats against the dug-out fencing, floor, or bench. There will be nothing done to distract players from the other team. If any of the above violations take place, the umpire will warn the person or persons involved. A second warning means automatic ejection from the game. If the umpire is unable to tell who the guilty party is, the head coach will be ejected from the game. Managers should remember whatever their players do - good or bad - reflects directly on them. Again, managers are expected to have control of their players.
- No smoking or chewing tobacco will be allowed in the confines of the playing field. Alcoholic beverages and drugs are not permitted anywhere in the ballparks.
- There will be no soft toss allowed against a fence at any ballpark during practice or before a game.
- Home team can be in either dug-out.
- Before the start of each game, the managers will meet with the umpires at home plate to discuss the ground rules and anything else important for the game.
- All equipment shall be kept in the dug-outs during the game. All players, unless they are on the field playing a position, on base, in coach's box, up at bat, or in the on-deck circle, will be in the dug-out.
- Managers should have their players in uniform with their shirts tucked in.
- Batting helmets: When a player is at bat, in the on-deck circle, being used as a coach, or a base runner, they must wear a helmet. This includes the team bat-boy. Helmets must be worn.
- Catchers mask and helmet: Any player warming up a pitcher must have on a helmet. This applies for both practices and games. Managers are to make sure a catcher has on a protective cup. If the catcher is not wearing a protective cup, they will be prevented from catching until they are wearing one.
- All on deck batters will use the third base on deck circle when a right-handed hitter is at the plate and will use the first base on deck circle when a left-handed batter is at he plate.
- All players will be listed in the batting order at the start of the game and bat in turn throughout the game. If the player arrives after the start of the game, their name is to be added to the end of the batting order.
- Free substitution on defense. However, each player will play at least two innings on defense unless prevented by injury or illness. If he/she does not, the player will start the next game in the field and play at least two innings on defense before being substituted for. Failure to do so can result in forfeiture.
- Due to a possible shortage of players, teams will be allowed to play a game with only seven (7) players. The team will be charged with only one (1) automatic out, not two (2), for the 8th and 9th spots.
- When playing with seven (7) players, a team may leave one infield position (other than the pitcher or catcher) open so the team may have two (2) outfielders.
- No team will be assessed an automatic out for the vacant 10th or later batting position.
- A line-up card must be turned in to the umpire ten (10) minutes before the game starts. All line-up changes are to be communicated directly to the home plate umpire by the team manager.
- Delaying of the game by runners will not be tolerated. The runner will receive one (1) warning by the umpire when a delay occurs. He will be called out if another infraction occurs.
- Stalling: If in the opinion of the umpire, a team exhibits stalling tactics, the umpire will give the team a warning. If in the opinion of the umpire, the team exhibits further stalling, the umpire shall stop the game and award a forfeit to the other team.
- All bats that meet any Baseball Organizations standards are legal unless they have been altered.
- The batter must not throw the bat after hitting the ball. If, in the umpire's judgement, the batter has thrown the bat, the batter will be called out and any baserunners go back to their original base.
- Between Innings Time Limit: For ages 9 - 15, there will be a one (1) and a half (1/2) minute time limit between innings. The umpire will have a stop watch to keep the time. Please have your pitcher and catcher ready to start warming up as soon as the other teams at-bat is over. A pitcher gets a maximum of five (5) pitches to warmup unless it's a new pitcher then they will be given the normal eight (8) pitches. Your catcher should have their gear on and ready to go when the inning is over.
- Courtesy Runners. A courtesy runner is required for a catcher that's on-base once there are two (2) outs in the inning. A courtesy runner is recommended, but not required, for the pitcher on-base once there are two (2) outs in the inning. The courtesy runner is the last batted out.
