16 inches

16-inch softball (sometimes called clincher, mushball, cabbageball, puffball, blooperball, smushball and Chicago ball) is a variant of softball, but using a bigger, squishy ball with no gloves or mitts on the fielders. Although it most closely resembles the original game as developed in the 19th century by George Hancock, today it remains popular almost exclusively in Chicago and New Orleans but is also popular in Portland, Oregon, where mushball has had leagues since the 1960s, and Atlanta, Georgia. The first set of rules were published in 1937 by the Amateur Softball Association, in the same manual as the rules for fastpitch softball.
