'interested' is the definition.
(thesaurus)

'know about player batting' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is found in the answer.
'player' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'know' could be 'ken' (Scottish term meaning to know) and 'ken' is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...

'to' acts as a link.
