Fungo, e.g. is a term used to describe a type of BAT used in baseball training. It is a lightweight BAT with a long handle and a large, round barrel. The term is derived from the Italian word 'fungo', which means 'SPINDLE'. Fungo bats are used by coaches to hit ground balls and fly balls to their players during practice sessions. They are also used to hit pop-ups to infielders and outfielders during defensive drills.
