Category 215 has a lot of these too. Most of these don't fit my "left side" "right side" theory though... and one has it listed with a "to" in front:
TEXT_OBJECT id="8758" text="a single to [%game ball direction]...(nl)[%game fielder] with no chance..."
Plus another call, so now I have groundball, flyball, and just ball direction.
Certainly all encompassing.
