Puppet winning fight (5-2)
I believe the answer is:
punch-up
'fight' is the definition.
(I know that punch-up is a type of fistfight)
'puppet winning' is the wordplay.
'puppet' becomes 'punch' (I've seen this before).
'winning' becomes 'up' (eg being up at half time in football).
'punch'+'up'='PUNCH-UP'
(Other definitions for punch-up that I've seen before include "Fisticuffs incident" , "An informal fist-fight or brawl - strike vertically?" , "Brawl (colloq.)" , "Fist fight" , "An informal brawl, a fight with fists" .)
