Fix your eye on the ball from the moment the pitcher holds it in his glove. Follow it as he throws to the plate and stay with it until the play is completed. Action takes place only where the ball goes.

William Joseph Klem born William Joseph Klimm (February 22 1874 – September 16 1951) known as the "father of baseball umpires" was a National League umpire in Major League Baseball from 1905 to 1941. Finally he was the last umpire to work the plate exclusively (traditionally the crew chief always worked the plate; today umpire crews rotate base/plate assignments). He was the first to straddle foul lines and stand to the catcher's side for better perspective.
