Dropped 3K in Series

[sprivitor]

Did any of you see the Series game where Tennessee on Defense against (Mich I believe). Anyway, catcher dropped 3rd strike on a check swing by batter. PU did not call strike on the wild pitch that went to the fence. Batter stood there a moment then decided to run. BU called batter out at first when catcher made throw to first.

The Mich coach seemed upset about it... Why would the BU call the runner out if the PU did not request assistance from his partner in determining if the batter went?

Is this normal?
