Fungo bats are, simply put, a long, skinny, and lightweight baseball bat used for fielding practice. Typically, they are around 34 to 37 inches in length and between 17 and 24 ounces in weight, give or take a couple of ounces. They will also almost always feature a 2 1/4 inch barrel diameter to allow for more control during a swing. As you can tell, fungo bats are longer than a normal baseball bat and much more lightweight in comparison. Most fungo bats are going to be made up of ash wood while there are some maple and bamboo wood fungo bats, some composite wood fungo bats, and very few aluminum alloy fungo bats. Almost all of these designs will be under $100 with very few eclipsing that mark. 

While many people view the fungo bat more as an antique piece of baseball’s history, there’s no doubt that it still has a special place in the modern game. Actually, the bat is starting to enjoy some revival all-round the game. Regardless of minimal production of fungo bats, you can rest assured that they’re here to stay. The bats are too beneficial to both coaches and players on a daily basis.
Baseball bats are made of either wood, or a metal alloy (typically aluminum). Most wooden bats are made from ash. Other woods include maple, hickory, and bamboo. Hickory has fallen into disfavor over its greater weight, which slows down bat speed, while maple bats gained popularity[5] following the introduction of the first major league sanctioned model in 1997. The first player to use one was Joe Carter of the Toronto Blue Jays.[6] Barry Bonds used maple bats the seasons he broke baseball's single-season home run record in 2001, and the career home run record in 2007.[6] In 2010, the increased tendency of maple bats to shatter has caused Major League Baseball to examine their use, banning some models in minor league play.[7][8]

A rounded, solid wooden or hollow aluminum bat. Wooden bats are traditionally made from ash wood, though maple and bamboo is also sometimes used. Aluminum bats are not permitted in professional leagues, but are frequently used in amateur leagues. Composite bats are also available, essentially wooden bats with a metal rod inside. Bamboo bats are also becoming popular.
Manufacturers position each bat's label over the mechanically weaker side of the wood.[9] To reduce chance of fracture,[9] and maybe deliver more energy to the ball,[10] a bat is intended to be held so the label faces sky or ground when it strikes the ball during a horizontal swing.[9] In this orientation, the bat is considered stiffer and less likely to break.[11]
Break your team up into 2 or 3 teams. If you do 2 teams you’ll need 8 or 9 on a team with a player for each defensive position. If you only have 8 on a team you can eliminate either the pitcher, catcher, or one outfielder based on what is a priority for your team that day.  If  you only have 12-15 players on your team break it up into 3 teams of 4-5. Then place two of the teams on defense and one team hitting fungoes. No matter what, have the teams and batting orders pre-made before practice. This will eliminate unnecessary downtime during practice.
The main goal of the game is to hit it to the pin in the least amount of strokes, similar to golf. Holes can consist of a certain sign in the outfield, in the tarp tunnel, off of the foul pole, onto the pitchers mound or off of a yardage marker on the outfield wall; it can really be anything on the field that can be hit without breaking. There can even be 2 part holes such as: First you have to hit the ball off of the scoreboard, then you have to hit the ball off of the right field foul pole.
