One of my favorite softball hitting drills is one that helps the batter learn to wait for the change up.
Soft Toss Drill
The batter is in their normal stance.
The tosser is directly behind home plate.
The batter must keep their eyes on on the “pitcher”.
The tosser tosses the pitch through the strike zone from behind
The batter who is still looking at the pitcher, sees the ball in their peripheral
vision, waits and swings trying to hit the back side of the ball and drive it towards second base or the center fielder.
It takes about 5-8 balls before the batter starts making contact. Once they get it they continue to improve.
Basketball Drill for Softball
A drill that I like doing is soft tossing deflated basketballs.
Because it teaches girls to stay thru a longer hitting zone and makes them gain power.
