All World Wiffle® Ball Championship events will utilize the same rules used in Major League Baseball, with the following exceptions:
1. Sportsmanship - All teams engaging in any behavior that the tournament director deems to be “unsportsmanlike conduct” will be removed from the tournament immediately at the director’s discretion. Because of the confined nature of the game and unique umpiring setup (see rule 2), fans and players watching games must refrain from commenting on calls. Failure to comply will result in a team, and or a fan’s removal from the park or facility. Captains are responsible for monitoring fan behavior. If that monitoring becomes difficult, the captain shall seek the assistance of a tournament official.
2. Umpiring - Teams will umpire their own games. Captains will settle all disputes over calls. Tournament officials will not rule on judgment calls. The home team will be decided by a coin toss or “the bat thing,” unless designated by the tournament schedule.
3. Equipment - All bats used in league play must be regulation, yellow Wiffle® bats. They may not be altered in any way; however they may have one layer of plastic or thin cloth tape on the handle. Balls must be baseball size Wiffle® brand. All shoes will be flat-soled (no cleats, turf shoes, spikes, etc.).
4. Rosters - All teams will have five players on their roster. Each team will have four or five players in the game at all times. (See rule 5.) No roster changes will be allowed under any circumstances, after tournament play begins.
5. Players in a game/optional designated hitters - Teams unable to field four rostered players, at any time, for any reason, will forfeit any games scheduled at that time. At the beginning of a game, teams may choose to play four players – or to utilize their fifth player as a designated hitter. When utilizing five players, if a player is removed for any reason during a game, that player may not re-enter the game (see rule 7) and that player’s at-bat in the order will become an automatic out for the remainder of that game. (See rule 18.)
6. Positions & Switches – Outfielders may play anywhere in the field. Catchers must be utilized behind the plate. Players may switch defensive positions at any time, including pitchers and catchers. Designated hitters will not play the field, however they may switch their DH position with any defensive player at any time. Regardless of position switches, batting orders will stay the same for the duration of games.
7. Substitutions may be made, however once a player leaves a game, that player may not return to the same game. Exception: If a player suffers a tournament-ending injury, a player who has previously left the game may re-enter that game as a sub.
8. Innings and slow play – All games will be six innings (also see rule 19. Unless a game is tied, after 50 minutes, new innings will not be initiated. In the event of a tie game after both 50 minutes and the end of any inning, extra inning rules will commence. (See rule 19.) Teams suspected of stalling will be cited by the director for “unsportsmanlike conduct” under rule 1 and removed from the tournament.
9. Pitching - All pitches must be slow and have an arc on them. (An arc is defined as: The ball, after release, reaching a point higher than the point of the pitcher’s release.) No sidearm pitching will be allowed. The batter will be the sole judge of all pitches and their proper speed and may demand legal and/or slower pitches. A pitcher who deliberately refuses to throw legal, hittable pitches after a reasonable period of time may be cited for "stalling" by the tournament director, which will be treated as a sportsmanship violation. (See enforcement under rule 1.) Balks are legal. The pitcher must have one foot on, and one foot in front of the rubber when the ball is released. No backpedaling will be allowed until the ball is released."
10. At bats - There will be no balls, walks (see rule 11), or called strikes. Batters may strike out swinging (including fouls before the third strike). Batters may choose not to swing at any pitch. Hit batters will not advance. One-handed batting will not be allowed for non-ADA players. Batters must have both feet entirely inside of the lines of the batter's box through the conclusion of each pitch.
11. Intentional walks - Each team may intentionally walk one batter per game (including any extra innings). The batter will go to first on the command of the pitcher.
12. Pitcher's Hand - All force plays on the batter going to first base may be made to the pitcher, who may be anywhere in fair or foul territory. The runner may also be put out by force at first base. All other force plays must be made to the bases or to home plate.
13. No infield fly rule will be in effect.
14. “Stealing” first base - Batters may not steal first base after the catcher drops strike three.
15. Stealing and leading off - Base runners may not lead off of first or second; nor may they steal second or third. Runners may lead off of third and, or steal home at any time. (See the extra inning exception in rule 19.) Runners on first and second may not leave their base during or immediately after plays on a runner attempting to steal home. Runners on first and second leaving their base before the batter makes contact with the ball will be out.
16. Pegging - Fielders may throw the ball at runners. Runners struck below the neck will be out. Runners hit below the neck with a thrown ball which first hits any player, a base, or the ground, will be out.
17. Runner/ball contact - Base runners in contact with a base that are hit with a batted or thrown ball will be safe. Base runners between bases hit with a batted or thrown ball will be out.
18. Home runs - All balls hit over the designated home run fence, fair or foul, will be home runs. (Exception: no foul ball home runs will be allowed where there is limited or irregular fencing in foul territory.) The batter and all base runners must touch all bases — in order — after a home run.
19. Extra innings – Unlike in the first six innings, runners on third may not lead off or steal. Each team will begin its half of all extra innings with two outs. The batter who made the last out in the previous inning will go to third base and the next batter will bat first.
5-Batter Teams: In the event that a 5-batter team is down a player (see rule 5) and subject to an automatic out, that missing batter’s at-bat will be an out, immediately ending that team’s half extra inning. Likewise, a removed player scheduled to take third at the beginning of a team’s half extra inning, will force that team to begin the inning with no base runners and two outs.
20. Mercy rule - If after the third inning, or at the end of any subsequent inning, a team leads by 15 runs or more, the game will be over. (If the home team leads by 15 or more runs after the top of the third or any later inning, the game will be over.)
21. The tournament director may resolve any and all conflicts regarding the interpretation of the above rules – or any loopholes therein – at his or her discretion. The director will not rule on judgment calls.
