Sci-Fi Saturday: The Courtside Chiller, Part V

Resolve, it sometimes falters, as does will,
And as the minutes passed, that eerie cry
Unsettled those who heard it. Soon its chill
Was too much even for the strong Coach Bly.
His incantation trailed off to a sob
Of guilt and failure. It seemed victory
Was going to the evil presence. Rob
A father of his pow'r to guard, to be
Protector, and he's easy to defeat.
But lo! From out the home team's locker room
Came figures, four, with gadgetry so neat
And knowledge so profound as would spell doom
For any haunting. Beams of searing light
That stank of ozone soon lit up the night!
