Second team's swindle (5)
I believe the answer is:
screw
'swindle' is the definition.
(I know that swindle is a more specific form of the action screw)
'second team's' is the wordplay.
'second' becomes 's' (common abbreviation).
'team' becomes 'crew' (crew is a kind of team).
's'+'crew'='SCREW'
(Other definitions for screw that I've seen before include "con" , "Wood fastener" , "Tapered fastener with a slotted head" , "Propeller (sl.)" , "Fasten; propeller" .)
