Where cricketers practise catches (4)

I believe the answer is:

nets

I'm a little stuck... Click here to teach me more about this clue!

'catches' is the definition.
(I know this)

I don't understand the rest of the clue.

(Other definitions for nets that I've seen before include "bags" , "Brings home" , "(Period for) cricket practice" , "Meshes to catch fish, say" , "Captures" .)

I've seen this clue in The Times and The Guardian.
