Small flap with stick raised (3)
I believe the answer is:
tab
'small flap' is the definition.
(I've seen this before)
'stick raised' is the wordplay.
'stick' becomes 'bat' (bat is a type of stick).
'raised' is a reversal indicator (going up in a down clue).
'bat' in reverse letter order is 'TAB'.
'with' is the link.
(Other definitions for tab that I've seen before include "Kind of label for bat" , "Check" , "Tally at bar (colloq.)" , "Till bill" , "ticket" .)
