It looks like I may be in the minority here, but to not throw a drop ball because the batter is up in the box is very short-sighted in my mind. While the batter's position in the box is certainly a factor in the decision on what pitch to throw, it is only one factor ... others include the count, the situation as to outs and base-runners, the batter's swing, what you've thrown them previously, what pitches are working that day, etc. Part (most?) of being a good pitcher is giving the batter different looks, spins and locations. My daughter was not a speed pitcher, but lived all the way through college on a good drop and a knuckle change. Had she not thrown the drop to batters who were up in the box on her, she never would have survived. As others have mentioned, you just need to keep it low and hit the location. And agree with Crystle that the drop need not and should not put any more torque on the arm.
