Team out before close of play in friendly (5)
I believe the answer is:
matey
'friendly' is the definition.
('matey' can be similar in meaning to 'friendly')
'team out before close of play' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'before close of play' becomes 'y' (I've seen this in other clues**).
'team' anagrammed gives 'mate'.
'mate'+'y'='MATEY'
'in' is the link.
(Other definitions for matey that I've seen before include "Pirate's chum (colloq.)" , "Sunshine" , "china" , "Friendly, sociable" , "Chummy" .)
