Sport that involves bats, net, and line (5,6)
I believe the answer is:
table tennis
'sport' is the definition.
(thesaurus)
'involves bats net and line' is the wordplay.
'involves' indicates an anagram.
'and' says to put letters next to each other (I've seen this in other clues).
'bats'+'net'='batsnet'
'batsnet' after 'line' is 'linebatsnet'.
'linebatsnet' with letters rearranged gives 'TABLE-TENNIS'.
'that' acts as a link.
(Other definitions for table tennis that I've seen before include "Ping pong" , "sport" , "Ping-pong" , "Indoor game" .)
