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.”
In 1990, Bruce Leinert came up with the idea of putting an axe handle on a baseball bat. He filed a patent application for the 'Axe Bat' in 2007 and the bat started being used in the college and pro ranks over the following years. In 2012, the Marietta College Pioneers baseball team won the NCAA Division III World Series using axe handled bats. Several Major League Baseball players have adopted the bat handle including Mookie Betts, Dustin Pedroia, George Springer, Kurt Suzuki and Dansby Swanson.
Many players "bone" their bats, meaning that before games, they rub their bats repeatedly with a hard object, believing this closes the pores on the wood and hardens the bat. Animal bones are a popular boning material, but rolling pins, soda bottles and the edge of a porcelain sink have also been used. Pete Rose had his own way of hardening his bats: he soaked them in a tub of motor oil in his basement then hung them up to dry.
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.
Maple bats in particular were once known (circa 2008) to potentially shatter in a way that resulted in many sharp edges, sometimes creating more dangerous projectiles when a bat broke. Maple bat manufacture evolved significantly, in cooperation with Major League Baseball, paying special attention to grain slope, and including an ink spot test to confirm safest wood grain orientation.
To figure out who shoots first, players usually throw or roll a baseball to a certain object (usually at close range) and whoever is closest shoots first. The first person then gets to choose the first hole and tees off. To tee off (and for most shots) players hit the ball like they were playing baseball, but depending on the distance from the hole the player may choose to ‘putt’ the ball instead of hitting it. To putt the ball, the player places the ball on the cup (the end of the fungo bat), and can toss the ball from the cup in hopes of getting a more accurate shot. In shooting or putting, the player must have one foot where the ball landed during the entire duration of their swing or putt, failure to keep the foot planted results in a loss of a stroke. Scorekeeping is identical to traditional golf; the player with the fewest strokes essentially wins the hole. Players traditionally play nine or eighteen holes of fungo golf, and at the end the person with the fewest strokes in the set number of holes wins the game.
