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.
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 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. 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. 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.
This sounds like a lot of information, but with a little practise on the coaches part, it runs quite smoothly. Two to three reps per player in the field per section is quite adequate, and with 14 men on the field, this whole routine should take about 7 minutes. It's quite snappy, and quite impressive. I had many a parent marvel to me after witnessing it - "you look like a professional team!" I wouldn't try the routine with anything less than a 14 yr old select team, but with the talent to do it right, it's fantastic.
Even in those formative years, authorities on the game warned the practice of hitting fungoes should be limited to coaches. Henry Chadwick, one of baseball’s earliest proponents, claimed “The weakest batting is shown when the batsmen indulges in fungo hitting,” according to the Art of Batting. Others agreed that the practice was bad for training a batter’s reflexes: “While watching some of our freshmen practicing ‘fungo’ batting the other afternoon it occurred to me that it was about the worst kind of practice a batsman could imagine in training his eye in batting,” a writer claimed in the March 3, 1886 edition of The Sporting Life. “It trains the eye to meet the ball in batting it in a manner which never occurs in actual play. It ought to be prohibited on every well regulated ball field.”
Fungo bats typically weigh between 17 to 22 ounces and may be as long as 37 inches, making them longer than most bats used for hitting. According to Pro Bats, a typical professional baseball player uses a bat that is about 34 inches long and weighs about 32 ounces, although there is considerable variation. Fungo bats not only are longer than regular bats, they also are skinnier. Like regular bats, fungo bats can be made of metal or wood.
A fungo bat's size and weight make it easier to operate with one hand or two. Coaches can toss a ball up with one hand and hit pop flies or ground balls farther and with greater accuracy with a fungo bat than with a regular bat. According to an article by LJWorld, high school baseball coach Brad Stoll said fungo bats allow him to hit more balls because heavier regular bats would "wear you out." Fungo bats should be used as a practice tool only and should not be used to hit a pitched ball.
