A fungo bat is specially designed bat used by baseball and softball coaches for practice purposes. The bat is designed to hit not thrown or pitched balls, but rather balls tossed up in the air. Typical fungo bats are 35–37 inches long and weigh 17–22 ounces. Coaches hit many balls during fielding practice, and the weight and length allow the coach to hit balls repeatedly with high accuracy. The small diameter also allows coaches to easily hit pop ups to catchers and infielders. Wikipedia definition of Fungo Bat
