Download the official NJWA rule book. The PDF includes the rules of: The Playing Field, The Playing Equipment, Teams, The Game, Game Situations, Base Runners, The Batter, The Pitcher, The Fielder(s), Officiating and Score Keeping, and Tournament Play.
The NJWA's strikezone, shown above, is 12 inches of the ground and 20 inches wide x 30 inches high. The target itself is made of sheet metal and the base is a five gallon bucket filled with cement.Behind the target is the PVC backstop which measures 8 ft x 8 ft and has green plastic snow fencing twist tied to it. The backstop helps speed up the games and makes it easier for both the pitcher and the batter. Chasing the ball around all game is not fun.
To start a league you'll have to have some Wiffle®Ball interest in your town. A good idea would be to go to your local newspaper(s) and give them a “Press Release” about a Wiffle®Ball league. Make sure to have your phone #, e-mail address and website (if you have one) included in the press release. You also have to have a good location. A local Babe Ruth field or a softball field is perfect. A field of this size can easily set up four or five Wiffle®Ball fields. Once you start getting interest set up a schedule dividing the teams into two divisions, American League and National League.
In 1953 the Wiffle Ball Inc. was founded by David N. Mullany. The first year there was not a bat for the game, only a broom stick was used to hit this funny plastic ball that curved and swirled when it was thrown. In 1954 the first Wiffle®Ball bat was made. It was made out of wood and was called the “Official Wiffle®King.” From 1954 to 1972 bats were made under the name “Official Wiffle®Bat.” In 1958 a two piece plastic bat was made that snapped together. This bat was never marketed. In 1959-1999 a one piece yellow plastic bat was made with “Official Wiffle®Bat” stamped on the side. This is the bat you see in the stores today.
The straight fastball is the easiest pitch to throw in the game of Wiffle®Ball. Holes should face home plate and the tips of the index and middle fingers should be placed over the top holes with the thumb on the bottom seem of the ball. The ring finger and pinky finger are together along the seem of the ball. Throwing the ball with a straight over hand motion will create the ball to go straight towards the target, even on a windy day. This grip is the same for a right handed pitcher and left handed pitcher. Do not grip the ball too tight, a nice loose grip is more effective.
