I do not verbalize all calls ,if the whole world knows the ball is foul or the player is out or safe I will signal my thoughts on this are that on close ones when I shout out the call with the signal it has more authority and is easier to sell the call. On balls and strikes ,for strikes (called) I will stand up use the hammer and call strike ,same motion for strike for strike three. Swing strike just the hammer ,for balls that the whole world knows it is a ball say nothing for all others I say it loud enough for batter and catcher to hear. Your thoughts.
