Batters dodging and weaving...congratulations, you get an A+ !
Of course, if you're putting guys on base that defeats the purpose. Without getting technical, let's keep it real simple to start...
Adjust your target.
Instead of aiming for the glove, you might try to aim for the catchers outside shoulder. Aim for the duggout if you have to, but don't continue to make the same mistakes ... learn from your prior pitch and adjust !
Never apologize for hitting a batter (accidentally) and don't be afraid to pitch inside. Throwing inside ? Bring it hard and bring it often !!
