A Fielding-Bunts Drill:
Catcher will assume their stance.
Coach will stand behind the catcher with a ball.
The coach will toss the ball over the catchers shoulder.
The catcher will field it and throw to a base.
A variation can used by telling the catcher that the runner has great speed and they must hurry.
Also, the coach can throw it far enough that a throw to first would be late.
The catcher will execute a full arm fake and throw out the lead runner who may have drifted off a base.
