Wall

The "wall" sometimes referred to as the "1-3-3" involves four players in the close defense. One player is the marker, also called the "rabbit", "chaser" or "puke" because they often have to run quickly between multiple handlers spread out across the field. The other three defenders form a horizontal "wall" or line across the field in front of the handler to stop throws to short in-cuts and prevent forward progress. The players in the second group of a zone defense, called "mids" and "deeps", position themselves further out to stop throws that escape the cup and fly upfield. Because a zone defense focuses defenders on stopping short passes, it leaves a large portion of the field to be covered by the remaining mid and deep players. Assuming that there are seven players on the field, and that a cup is in effect, this leaves four players to cover the rest of the field. In fact, usually only one deep player is used to cover hucks (the "deep-deep"), with two others defending the sidelines and possibly a single "mid-mid". A variation of the 1-3-3 is to have two markers: The "rabbit" marks in the middle third and strike side third of the field. The goal is for the "rabbit" to trap the thrower and collapse a cup around him. If the rabbit is broken for large horizontal yardage, or if the disc reaches the break side third of the field, the break side defender of the front wall marks the throw. In this variation the force is directed one way. This variation plays to the strength of a superior marking "rabbit".
Alternately, the mids and deeps can play a one-to-one defense on the players who are outside of the cup or cutting deep, although frequent switching might be necessary.
