I believe the answer is:

opener

I'm a little stuck... Click here to teach me more about this clue!

'batsman?' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for opener that I've seen before include "device for getting at the drink" , "Introductory remark" , "batsman facing the first ball?" , "Card player who starts the bidding" , "player, first to bat" .)

I've seen this clue in the Evening Standard.
