re: "but doesn't it worry you that a varsity high school umpire even needed to ask for help on a play as simple as this."
Most high school officials are just that - high school officials, and not professional who work major league games.
More than likely most of these officials do it as a means of a "meager" secondary income.
One needs to be aware of the amount of mandatory training time required, length of travel time to and from game sites, game lengths, equipment costs, along with the all too common BS thrown at an officials, then balance all this against the financial returns.
When it is all said and done, you get what you pay for in most areas of life.
