Once in a while, veteran managers revive it. The Giants took infield occasionally in 2008 and 2013 under Bruce Bochy, and Jim Leyland instituted infield drills before batting practice late in his tenure in Detroit. Molitor, for one, misses it. He took infield even as a designated hitter late in his career because he hated sitting around for almost two hours waiting to play.
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.
