This is the drill we ran all through high school. It is the most time effective and skill intensive way to warm up a team, but your boys must be able to play catch! Fungo-ers stand in the "fungoe circles" that any good field has (and if it doesn't, you know where they're supposed to be - just outside of the home-plate dirt circle, towards the dugouts). The catch to this method is this - you have two first basemen, allowing both sides of the infield to throw across. Herein lies the only danger - one of the firstbasemen has a lengthy throw back to a shagger, so caution must be excersized (a catcher with a good head on his shoulders really helps).
Within league standards there is ample latitude for individual variation, many batters settling on their own bat profile, or one used by a successful batter. Formerly, bats were hand-turned from a template with precise calibration points; today they are machine-turned to a fixed metal template. Historically significant templates may be kept in a bat manufacturers' vault; for example, Babe Ruth's template, which became popular among major-league players, is R43 in the Louisville Slugger archives.
To practice throwing around the infield, Bates recommends several drills you can use. The first involves placing four fielders in a square, about 15 feet apart. The players flip the ball underhanded to each other, like in a double play. Keep their arms straight, using a stiff wrist, with gloves on their hips once the ball is out. Every fielder follows their flip, glove side first, rotating around the square. The idea is to have a sequence of catch, flip and follow. The ball should be caught with two hands, palms open. After about two minutes, repeat the process rotating the other way for another two minutes.
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.
