Even in those formative years, authorities on the game warned the practice of hitting fungoes should be limited to coaches. Henry Chadwick, one of baseball’s earliest proponents, claimed “The weakest batting is shown when the batsmen indulges in fungo hitting,” according to the Art of Batting. Others agreed that the practice was bad for training a batter’s reflexes: “While watching some of our freshmen practicing ‘fungo’ batting the other afternoon it occurred to me that it was about the worst kind of practice a batsman could imagine in training his eye in batting,” a writer claimed in the March 3, 1886 edition of The Sporting Life. “It trains the eye to meet the ball in batting it in a manner which never occurs in actual play. It ought to be prohibited on every well regulated ball field.”
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.”
A fungo bat is used by the coach to hit ground balls or fly balls to his team. All throughout high school and college many players use fungo bats to play fungo golf. This is when each person has a fungo bat and a baseball and they pick out targets around their field or complex and basically play it in the same manner as golf. Fungo bats should not be used to hit a pitched baseball because they are much weaker than normal bats and will break much much easier.
Fungo bats aren’t typical bats like the ones Mike Trout takes with him to a game situation. Rather, they’re more of practice bats. The bats are specially made for coaches to utilize when testing the fielding of their players. For example, a coach would break out his or her fungo bat when he or she is looking to hit his or her shortstop a couple of ground balls or when he/she hits pop flies to the centerfielder.
There are limitations to how much and where a baseball player may apply pine tar to a baseball bat. According to Rule 1.10(c) of the Major League Baseball Rulebook, it is not allowed more than 18 inches up from the bottom handle. An infamous example of the rule in execution is the Pine Tar Incident on July 24, 1983. Rules 1.10 and 6.06 were later changed to reflect the intent of Major League Baseball, as exemplified by the league president's ruling. Rule 1.10 now only requires that the bat be removed from the game if discovered after being used in a game; it no longer necessitates any change to the results of any play which may have taken place. Rule 6.06 refers only to bats that are "altered or tampered with in such a way to improve the distance factor or cause an unusual reaction on the baseball. This includes, bats that are filled, flat-surfaced, nailed, hollowed, grooved or covered with a substance such as paraffin, wax, etc." It no longer makes any mention of an "illegally batted ball". In 2001, MLB approved the use of Gorilla Gold Grip Enhancer in major and minor league games as an alternative to pine tar.
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.
Do this for about three minutes, then collect the balls and work on 5-3, 6-4, and 4-6 plays for another three minutes. This is followed by hitting balls to the 5-6 hole. If the third baseman doesn’t get it, he retreats back to third, and the shortstop flips to third for a force-out, rather than throwing across or turn a long double play. The other fungo batter hits balls to the second baseman, who works on throwing to first.
