I'm a little stuck... Click here to teach me more about this clue!

'not from one of the big names?' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'over with new ball possibly' is the wordplay.
'over' becomes 'o' (cricket abbreviation**).
'with' says to put letters next to each other.
'possibly' indicates an anagram.
'new'+'ball'='newball'
'newball' is an anagram of 'wnlabel'.
'o'+'wnlabel'='OWN LABEL'

Can you help me to learn more?
