Win back, as losses (6)
I believe the answer is:
recoup
'win back as losses' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for recoup that I've seen before include "Reimburse or compensate" , "Get back or recover - say losses" , "Get back one's losses" , "Regain (something lost)" , "recover money" .)
