I guess I personally don't feel that chalk or dirt is a foreign substance. As soon as a ball touches the ground whether by pitch or hit, it's going to have dirt and/or chalk on it. Are you changing to a new ball after every pitch? Most players will have dirt/chalk in their gloves by just using them and that's going to get on the ball as well. If a pitcher puts some dirt/chalk on his/her hand, I'm not too concerned about it. Heck, I've had pitchers almost bury the ball in dirt before they pitched it. Playing in wet conditions, the ball gets wet, the pitcher dries it off with some infield dirt, I'm not saying anything. It's not giving them any advantage that I can see.
