If U3 starts on the shortstop side of second base, what should they avoid when the play develops?

When U3 starts on the shortstop side of second base, it is crucial to maintain a clear line of vision to effectively make calls regarding the play. Calling from a straight-lined position from first to second ensures that the umpire can accurately assess plays between those bases, reducing the chance of obstruction or compromising their angle of vision. This positioning allows for better visibility of potential plays, such as force-outs or tag plays at second base.

Other options, while they may seem relevant, do not align with the primary objective of ensuring clarity and visibility during the play. For example, moving towards home plate could obstruct the umpire's view of the critical actions occurring at second base. Positioning behind the shortstop might limit the umpire's sightlines and could lead to missed calls. Similarly, entering the outfield may remove the umpire further away from where the key actions are taking place, which can be detrimental to decision-making. Thus, maintaining a clear calling line while avoiding these other movements is essential for effective umpiring.
