Tennis strategy (3)
I believe the answer is:
lob
'tennis strategy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lob that I've seen before include "Lofted ball" , "Shot of Murray" , "Throw in high, slow arc" , "Send in a high arc as in tennis or cricket" , "Hit a ball in a high arc" .)
