The fungo is used by a coach to hit balls for defense practice. It is lighter weight, so less fatiguing to hit ball after ball. The fungo sheds its weight above the hands. The severely tapered barrel to drops weight and maintains a high moment of inertia. While the bat would be at greater risk of breaking if used in a live batting exercise, it is safe to use in practice because there are much fewer mis-hits.
Fungo bats are typically only used by coaches, to consistently place grounders and pop flies to their fielders for practice purposes. And with a fungo bat in their hands, some coaches can pull off wicked accuracy – as one story goes, the late California Angels player and coach Jimmie Reese once shot an 82 on an 18-hole golf course using nothing but a putter and a fungo bat.
Secondly, the first base fungo hits balls to the third baseman, who turns a double play with the second baseman to the normal first baseman, while the third base fungo hits balls to the shortstop, who throws to a shortened deep firstbaseman (this means that the deep firstbaseman stands closer to the shortstop than normal, so that the throw across this infield is the correct distance - this does NOT mean that the deep man stands any closer to the normal first base position - this length should always be sufficient)
