Begrudge losing set seventy played (4)
I believe the answer is:
envy
'begrudge' is the definition.
('envy' can be a synonym of 'begrudge')
'losing set seventy played' is the wordplay.
'losing' suggests deleting specific letters.
'played' indicates anagramming the letters.
'seventy' with 'set' taken out is 'veny'.
'veny' is an anagram of 'ENVY'.
(Other definitions for envy that I've seen before include "Desire as a rival" , "Deadly sin; sounds like two letters" , "Resentment at another's success" , "Begrudge, covet" , "grudging discontent" .)
