The fungo is used by a coach to hit balls for defense practice. It is lighter weight, so less fatiguing to hit ball after ball. The fungo sheds its weight above the hands. The severely tapered barrel to drops weight and maintains a high moment of inertia. While the bat would be at greater risk of breaking if used in a live batting exercise, it is safe to use in practice because there are much fewer mis-hits.
Players can be very particular about their bats. Ted Williams cleaned his bats with alcohol every night and periodically took them to the post office to weigh them. "Bats pick up condensation and dirt lying around on the ground," he wrote, "They can gain an ounce or more in a surprisingly short time." Ichiro Suzuki also takes great care that his bats do not accumulate moisture and thus gain weight: he stores his bats in humidors, one in the club house and another, a portable one, for the road. Rod Carew fought moisture by storing his bats in a box full of sawdust in the warmest part of his house. "The sawdust acts as a buffer between the bats and the environment," he explained, "absorbing any moisture before it can seep into the wood."
The Wright & Ditsons Lajoie baseball bat. This bat had a normal size barrel but had two knobs on the handle. The lowest knob was at the bottom of the handle and the other knob was roughly two inches above the lowest knob. This was designed to have better spacing between the hands due to the knob being in the middle of the grip. This also gave batters an advantage when they choked up on the bat, because the second knob provided a better grip.
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.
“They’re not moving, their feet are apart, their gloves are on the ground, backs are flat, and they’re working down to up, out to in, basically a steady roll back and forth probably 15 to 20 each,” Bates said. “Then they’ll turn their body, work glove side for another 15 to 20, and backhand 15 to 20. No movement, really, just making sure we’re watching the ball roll into our glove, fielding it, and doing all the things fundamentally correct.”
