Game involving line, net, bats (5,6)
I believe the answer is:
table tennis
'game' is the definition.
(I know that table tennis is a type of table game)
'involving line net bats' is the wordplay.
'involving' is an anagram indicator.
'line'+'net'+'bats'='linenetbats'
'linenetbats' with letters rearranged gives 'TABLE-TENNIS'.
(Other definitions for table tennis that I've seen before include "Ping pong" , "sport" , "Indoor game" , "Ping-pong" .)
