Here are two baseball drills I like.
For fielding, have the kids take off their cap and hold it in their mouth (biting on the bill of the cap) then roll or hit soft
grounders to them. This forces them to field the ball in front of them, and not wait until the ball gets between their legs to try
and stop it….works great.
For batting get a bag of uncooked beans (the little white ones) and toss them to the kids (about 10 feet away). The kids hit away at
the beans. Even though they are small, and don’t fly straight you’ll be suprised how fast the kids learn to hit them, developing
their “batter’s eye.”
