Spins googlies at both ends: unacceptable batting first (7)

'spins' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's an association between them I don't understand?

'googlies at both ends unacceptable batting first' is the wordplay.
'at both ends' says to hollow out the word (remove centre letters) (only the letters at the ends of the word).
'unacceptable' becomes 'out' (out can mean incorrect or inappropriate).
'batting' becomes 'in' (cricket term).
'first' says to put letters next to each other.
'googlies' with its centre removed is 'gs'.
'out'+'in'='outin'
'gs' after 'outin' is 'OUTINGS'.

Can you help me to learn more?
