Egg throw/soft hands technique drill
Allow infielders to work on developing soft hands when catching the ball
Take a raw egg and have yourself and another coach stand about 2-3 meters apart.
As you toss the egg to the other coach, you show them that in order for him to catch the egg without breaking that he must have soft hands and catch it gently while at the same time he must sweep the egg in his hands into his belly.
The same as pulling the glove up from a grounder and sweeping the glove up into your belly before throwing.
To make your point even further, you make sure an egg breaks on you as you catch it showing how “hard hands” and “stiff arms” are the improper way to receive an egg/ball.
During practices and games remind them “to get set and have egg hands”.
