Catches for cricket practice (4)
I believe the answer is:
nets
I believe this is a double definition.
'catches' is the first definition.
(I know this)
'cricket practice' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for nets that I've seen before include "Cricket practice venue" , "Lacy curtains" , "(Period for) cricket practice" , "Meshes to catch fish, say" , "Captures" .)
