What are some good baseball or softball drills that you can practice by yourself?

Throw a ball against a wall and practice fielding. Focus on your form. Stay low, keep your knees bent and bring the ball toward you as you field it.

Once you have that down, throw the ball at an angle and practice your forehand and backhand fielding. Each requires a drop-step in a different direction.

As you improve, throw the ball harder and harder.
