When batting you need to have the batting stance. Elbows out, not to your side, non-dominant arm's elbow pointed at the pitcher. You should also be leaning backward on your dominant foot. You should also be horizontal to the pitcher. Afterthat, when the ball is in your sight and is out of the pitcher's hand, slide your dominant foot towards the pitcher, swing the bat and follow through. In offensive positions you usually have one foot on the base and one stepping off. You should be looking at the pitcher or batter and most of the time the catcher. Also, knees bent and hands on your knees can be very affective to get you ready to run.
