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.
Fungo golf is a game involving two or more players in which they use fungo bats and baseballs and their object is to hit certain objects at a field. Fungo golf is played very similar to golf, where the player with the fewest strokes after a certain number of holes (typically nine or eighteen) wins the game. While there is no concrete history of how fungo golf was created, it has spread throughout America as a popular game especially with baseball players and coaches.
