Yours truly in goal? Correct (5)
I believe the answer is:
emend
'correct' is the definition.
(thesaurus)
'yours truly in goal?' is the wordplay.
'yours truly' becomes 'me'.
'in' indicates putting letters inside.
'goal?' becomes 'end' ('end' can be a synonym of 'goal').
'me' placed inside 'end' is 'EMEND'.
(Other definitions for emend that I've seen before include "Polish" , "would appear better" , "Improve by altering" , "Rectify" , "Alter to improve (text)" .)
