Team Rosters
- To be eligible to participate, a player must sign the team roster, acknowledging the liability waiver and code of conduct. A complete roster is required for all teams. All team managers must submit their team roster via TeamSideline before the first game.

- Fall Season: fourth scheduled week.
- Players may not appear on 2 rosters within the same division. Dual registration is permitted; however, they cannot be in the same league. Schedules will not be adjusted in league play, make-up, or playoffs to accommodate players participating in more than one league.
- All players must be 18 years of age.
- Protest of eligible players must be done before a player bats for the first time. Players must have a legally accepted picture ID (i.e., driver’s license) at the complex for all games. In league play, players who are protested for eligibility must be able to produce a picture ID. If no proof of picture ID is presented, the player is ineligible to continue participating in that game. If no proof of ID is presented to league officials within 24 hours, the game is forfeited. If a team is reduced to less than eight players because of eligibility, the game is a forfeit.
- Men may only play in men’s or coed leagues. Women may only play in women’s or coed leagues.
Weather Cancellations
The city of Arvada determines field playability. Field condition decisions are made by 1 pm.
The umpire and field supervisor are empowered to call a game at any time because of darkness, rain, lightning, or any other unsafe conditions that might arise. In this event, if four innings have been played, the games will be considered completed regardless of the score.
League Classification
We do our best to appropriately place teams into leagues; however, we reserve the right to place teams and merge leagues as we see fit. The league supervisors and the athletics department will monitor teams and players, and if it is deemed a team and players are incorrectly classified, they may move teams or players up or down accordingly in future leagues. To help determine the proper classification for your team, please use the following guidelines:
- Class Competitive (2 home runs (HRs) + 1 up to a total of 3): This league is geared towards the tournament teams.
- Class Upper (2 HRs): Teams play at a high level. At least 75% of players have above-average skills, with the remaining players having average skills. All players have a solid understanding of the game. These teams want to win.
- Class Lower (1 HR): Teams have no more than 50% of players that have above-average skills. The remaining players are average or less skilled. Teams want to win but are not competitive enough to play in the upper league.
Note: Leagues may be combined into an open division (1 HR +1 up to a total of 2), but there are not enough teams to run independently.
Season Formats
- Spring: 6-game season. No tournament.
- Summer:
- 12-game season. The top four teams playoff for the overall winner. Tuesday, Wednesday and Thursday
- 10-game season. The top four teams playoff for the overall winner. Monday and Friday

- Picking up players the night of the game: With the permission of the other team, players may be picked up to prevent forfeiture. Once a team gives permission for the opposing team to pick up players, they are committed to the result of the game and cannot protest.
- Additional Player
- A team may insert additional players into their lineup of up to 14 players.
- The batting order must remain consistent; however, any 10 players can play defensive positions.
- Any player in the lineup must be present at the beginning of the game. If the lineup has less than 10 players at the beginning of the game, you can add additional players up to 10 when players arrive. Any other players arriving after the start of the game will become substitutes.
- Any player withdrawn from the game for a substitute may re-enter the game once for the same player that they were pulled for.
- They must bat in the same place in the batting order from the beginning of the game.
- Pitching Arc is 6 ft to 10 ft from the ground. No fake pitches, quick pitches, or herky-jerky motions in any league. The pitcher must present the ball and release it while having one foot touching the mound.
- Batter's Count: Each batter will start with one ball and one strike count when they step into the batter’s box. There will be one courtesy foul ball on two strikes. The strike mat will not be used.
- Home Run (HR): “Hit and Sit” on home runs hit over the fence. All runners may clear the bases. All runs will count.
- Home runs must be retrieved by the team who hit the ball by the end of the inning. The game clock will not stop if the umpire runs out of balls.
- The first HR after a team’s allotted HR will be considered an out.
- If a team hits a second HR over the allotted HRs, it will end the inning.
- If a team hits a third HR over the allotted HRs, it will result in an offensive ejection. The player will be able to play defensively, but an out will be recorded very time their spot comes to bat.
- Double First Base: When a ball is hit in such a manner that there is going to be a play at first base, the batter must run to the orange base, and the defender must use the white base. If the runner hits the white base, they will be called out. If the fielder hits the orange base, the runner will be called safe. The orange base is only live the first time the runner runs past the base.
- Courtesy Runner: With the agreement of the opposing manager, the team may use a courtesy runner. The proceeding batter, who is not a base runner, will be the courtesy runner. Courtesy runners must be the same sex of the runner they are replacing. If the courtesy runner is on base when their spot in the lineup comes up to bat, an out will be recorded at the plate.
- Base Running: With the various skill levels in our league, we cannot enforce a “slide rule.” However, it is mandatory that the runner gets down, gets out of the way, or gives yourself up. Intent will be a judgment call from the umpire and staff. Although wild overthrows are part of the game and accidents happen, this rule is in place to prevent injuries and collisions.
- Fielders: Do not block the base. Stay to the side of the base. Runners have the right of way to the base. Being safe is more important than getting the out.
- Extra Inning Play: All tied games at the end of regulation game time will go to a one-pitch per batter inning.
- The first extra inning, the last batter from regulation play will start on second base.
- If games go into more extra innings, the last batter of the previous inning will start on third base.
- Each batter will only get 1 pitch to hit. If the ball isn’t hit in play, the result of the pitch is:
- Ball = walk
- Strike = out
- Foul = out
