Field a throw (5)
I believe the answer is:
pitch
I believe this is a double definition.
'field' is the first definition.
(I know that pitch is a type of field)
'a throw' is the second definition.
(I know that fling is the is a more specific form of the action of pitch.)
(Other definitions for pitch that I've seen before include "Field of play" , "Timbre" , "Many games require it" , "Area for games" , "Toss onto the playing field" .)
