Break your team up into 2 or 3 teams. If you do 2 teams you’ll need 8 or 9 on a team with a player for each defensive position. If you only have 8 on a team you can eliminate either the pitcher, catcher, or one outfielder based on what is a priority for your team that day.  If  you only have 12-15 players on your team break it up into 3 teams of 4-5. Then place two of the teams on defense and one team hitting fungoes. No matter what, have the teams and batting orders pre-made before practice. This will eliminate unnecessary downtime during practice.
Before we get started, we have to define the word "fungo" or "fungoes." To summarize, fungo (fungoes for plural) is a ball tossed into the air by the batter and struck as it comes down during practice sessions.  If you are a coach, you are more than likely familiar with a fungo bat. Or, if you are a player who has ever worked on ground balls or pop-flys in practice, you should know what a fungo bat is, as well. For the rest of us, a fungo bat might as well be a foreign object. What is that oddly shaped, extra long practice bat? So, let's answer the most common fungo bat questions:
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.[citation needed]

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.
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."[25]
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 also create complex holes such as ‘two-part holes’ where the players must hit or reach one object before attempting to shoot at the hole. For example, a ‘two-part hole’ could consist of hitting the scoreboard first, and then once they have hit the scoreboard they must hit the ball back to home plate, that would be one hole with the player with the fewest strokes winning the hole. ‘Two-part holes’ are typically saved for the last hole in order to make things more complex and difficult on the leader.
