Children's game, it could be golf! (3)

Ross

I believe the answer is:

tig

'children's game' is the definition.

'it could be golf' is the wordplay.
'could be' indicates anagramming the letters.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'it' is an anagram of 'ti'.
'ti'+'g'='TIG'

I've seen this clue in the Evening Standard.
