For starters, we should clarify just what we’re talking about when we say fungo bat. Longer, lighter and thinner than a regulation bat (but a larger barrel), a fungo bat is typically 35 to 37 inches long, and weighs between 17 and 22 ounces. As David Allison wrote in the June 1978 edition of Country Journal, “A fungo bat looks to be a cross between a baseball bat and a broomstick.”
Next, third base fungo hits to left, who throw to second, SS cuts (make a few of these the "cut off a double on a ball hit into the corner" variety - timing becomes important here, as the other fungo needs to hit many fewer balls than the fungo hitting to left). First base fungo hits to right, who come home, first baseman is cutoff, 60' from home (about pitchers mound - this postitioning puts him out of harms way should the SS overthrow second). On the throws home from right, make sure that they are the "normal" kind - hit the cutoff man, and don't hit too many. The right fielders will get to go again, as they're last throws will be the "do-or die" variety.
The bat's form has become more refined over time. In the mid-19th century, baseball batters were known to shape or whittle their own bats by hand. This allowed there to be a wide variety in shape, size, and weight. For example, there were flat bats, round bats, short bats, and fat bats. Earlier bats were known to be much heavier and larger than today's regulated ones. During the 19th century, many shapes were experimented with, as well as handle designs. Today, bats are much more uniform in design.
The most obvious reasons to utilize a fungo bat is the fact that it’s lightweight. It’s handy to coaches when conducting fielding practice since he or she has to hit plenty of balls to warm up his or her players. What is for sure is that hitting countless balls during practice can be tiring. Consequently, having a bat that’s lighter weight is magical at preventing the coach and/or players from getting tired.
A fungo bat's size and weight make it easier to operate with one hand or two. Coaches can toss a ball up with one hand and hit pop flies or ground balls farther and with greater accuracy with a fungo bat than with a regular bat. According to an article by LJWorld, high school baseball coach Brad Stoll said fungo bats allow him to hit more balls because heavier regular bats would "wear you out." Fungo bats should be used as a practice tool only and should not be used to hit a pitched ball.
