Abstract A vertically suspended loop to which a flexible net is attached serves to judge if a pitched ball approximately passes through the strike zone above the batter''s plate in the game of baseball (or a related game). A pitched ball, not swung at by the batter, which passes through the loop and is subsequently retained by the net shall be called a ''''strike,'''' whereas a pitched ball, not swung at, and not passing into the net shall be ruled a ''''ball.'''' The loop is suspended by suspension members between a pair of vertical, spaced apart posts such that the posts and loop all be substantially in the same vertical. The loop being suspended at a height above a support surface which is substantially the height of the strike zone of a batter.
