Bishop attending cricket club (3)
I believe the answer is:
bat
'cricket club' is the definition.
(I've seen this before)
'bishop attending' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'attending' becomes 'at' (e.g. at school means attending school).
'b'+'at'='BAT'
(Other definitions for bat that I've seen before include "The cricketer wields it" , "Wooden implement for cricket" , "Small mammal or cricket striker" , "Small flying mammal - like 11 Across" , "once wielded by 60 [GREIG]" .)
