I would be interested in seeing data on the at-bat results immediately following coaching visits to the mound. Obviously some visits are purely to allow time for the bullpen to get warm, but I would be interested in knowing the effectiveness of pitching coaches settling pitchers down and getting positive results from their visits to the mound. Would this be an effective measure of the ability of the pitching coach? Does the demeanor of the pitcher have more to do with the situations? Does anyone know if any data has been collected on this before?
