"…I can proudly say I've completed my 21 year career as a Major League Umpire and have worked three world series. I am now an MLB Umpire Supervisor. Without the influence of people like Bill McCallum, this would not be possible!"
Good umpires (new or experienced) have good mechanics, habits and patterns of behavior. It is not enough to acquire the proper information, but to learn to put it to practice. Proper development and continued reinforcement of knowledge and skills are essential to achieving high success on the field. If we are not constantly improving, then others are passing us by!
