The chap least wanted for his batting? (4,3)

'least wanted for his batting?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'the chap' is the wordplay.
I cannot really see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'chap' could be 'man' (chap can mean a man) and 'man' is found within the answer.
The remaining letters 'las' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
