Setup a tee for hitting (soft-toss can also be used). When executing swings, the lead hand, you should concentrate on keeping the hand above the plane of the ball. If the lead hand drops under, a pop up, stike out or fly out will usually occur. The hitter must also turn the hips quickly for proper timing and power. The lead elbow should not extend fully before contact with the ball, since that will slow down the bat swing.
